Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements of Eaton Corporation plc (Eaton or the Company) have been prepared in accordance with generally accepted accounting principles for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by United States generally accepted accounting principles (US GAAP) for complete financial statements. However, in the opinion of management, all adjustments (consisting of normal recurring accruals) have been made that are necessary for a fair presentation of the condensed consolidated financial statements for the interim periods. This Form 10-Q should be read in conjunction with the consolidated financial statements and related notes included in Eaton’s 2017 Form 10-K. The interim period results are not necessarily indicative of the results to be expected for the full year. Management has evaluated subsequent events through the date this Form 10-Q was filed with the Securities and Exchange Commission. During the first quarter of 2018, Eaton re-segmented certain reportable operating segments due to a reorganization of the Company's businesses. The new reportable business segment is eMobility (which includes certain legacy Electrical Products and Vehicle product lines). See Note 14 for additional information related to these segments. Certain prior year amounts have been reclassified to conform to the current year presentation. Revenue Recognition Sales are recognized when control of promised goods or services are transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services. The majority of the Company’s sales agreements contain performance obligations satisfied at a point in time when control is transferred to the customer. Sales recognized over time are generally accounted for using an input measure to determine progress completed at the end of the period. Sales for service contracts generally are recognized as the services are provided. For agreements with multiple performance obligations, judgment is required to determine whether performance obligations specified in these agreements are distinct and should be accounted for as separate revenue transactions for recognition purposes. In these types of agreements, we generally allocate sales price to each distinct obligation based on the price of each item sold in separate transactions. Payment terms vary by the type and location of the customer and the products or services offered. Generally, the time between when revenue is recognized and payment is due is not significant. Eaton does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year. Sales, value added, and other taxes collected concurrent with revenue are excluded from sales. Shipping and handling costs are treated as fulfillment costs and are included in Cost of products sold. Eaton records reductions to sales for returns, and customer and distributor incentives, primarily comprised of rebates, at the time of the initial sale. Rebates are estimated based on sales terms, historical experience, trend analysis, and projected market conditions in the various markets served. The rebate programs offered vary across businesses due to the numerous markets Eaton serves, but the most common incentives relate to amounts paid or credited to customers for achieving defined volume levels. Returns are estimated at the time of the sale primarily based on historical experience and recorded gross on the Consolidated Balance Sheet. See Note 4 for additional information. Adoption of New Accounting Standards Eaton adopted Accounting Standard Update 2014-09, Revenue from Contracts with Customers, at the start of the first quarter of 2018 using the modified retrospective approach and recorded a cumulative effect adjustment to retained earnings based on the current terms and conditions for open contracts as of January 1, 2018. The adoption of the standard did not have a material impact on the Company’s Consolidated financial statements. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. Consolidated Balance Sheet Balance at December 31, 2017 Adjustments due to ASU 2014-09 Balance at January 1, 2018 Assets Accounts receivable - net $ 3,943 $ (99 ) $ 3,844 Prepaid expenses and other current assets 679 129 808 Deferred income taxes 253 1 254 Liabilities and shareholders' equity Other current liabilities $ 1,872 $ 33 $ 1,905 Eaton shareholders' equity 17,253 (2 ) 17,251 Eaton adopted Accounting Standards Update 2016-16, Intra-Entity Transfers of Assets Other Than Inventory (ASU 2016-16), at the start of the first quarter of 2018. This accounting standard requires companies to recognize the income tax effects of intercompany sales and transfers of assets other than inventory in the period in which the transfer occurs. The previous accounting standard required companies to defer the income tax effects of intercompany transfers of assets by recording a prepaid tax, until such assets were sold to an outside party or otherwise recognized. ASU 2016-16 requires companies to write off any income tax amounts that had been deferred as prepaid taxes from past intercompany transactions, and record deferred tax balances for amounts that have not been recognized, through a cumulative-effect adjustment to retained earnings. Upon adoption, the Company recorded a cumulative-effect adjustment of $199 to reduce retained earnings. Eaton adopted Accounting Standards Update 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (ASU 2017-07), at the start of the first quarter of 2018. The new standard requires companies to present service costs consistent with other employee compensation costs on the income statement and separate from all other elements of pension costs. The retrospective adoption of this standard resulted in an increase in selling and administrative expense with a corresponding decrease in Other expense - net of $2 for the nine months ended September 30, 2018 , and a reduction in selling and administrative expense with a corresponding increase in Other expense - net of $34 for the nine months ended September 30, 2017 . Recently Issued Accounting Pronouncement In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (Topic 842), (ASU 2016-02). This accounting standard requires that a lessee recognize a lease asset and a lease liability on its balance sheet for all leases, including operating leases, with a term greater than 12 months. ASU 2016-02 will require additional disclosures in the notes to the consolidated financial statements and is effective for annual and interim reporting periods beginning after December 15, 2018. The Company plans to adopt the standard, and related amendments, as of the first quarter of 2019 using the optional transition method that allows for a cumulative-effect adjustment to be recorded at adoption, and will not restate prior periods. A project team has been formed to evaluate and implement the new standard. The project team has been collecting and validating the data required to account for leases under the new standard, and continues to test the functionality of a new lease accounting system being developed by a third-party. In addition, the Company is in the process of identifying and implementing the appropriate changes to business processes and controls to support recognition and disclosure under the new standard. Eaton is evaluating the impact of ASU 2016-02 and expects to recognize a significant lease asset and lease liability for operating leases on the Consolidated Balance Sheet, but does not expect a material impact to the Consolidated Statements of Income or Cash Flows.

Equity Method Investments and Joint Ventures [Abstract]
SALE OF A BUSINESS	Note 2. SALE OF A BUSINESS Sale of heavy-duty and medium-duty commercial vehicle automated transmission business On July 31, 2017, Eaton sold a 50% interest in its heavy-duty and medium-duty commercial vehicle automated transmission business for $600 in cash to Cummins, Inc. The new joint venture is named Eaton Cummins Automated Transmission Technologies (ECATT). In 2017, the Company recognized a pre-tax gain of $1,077 , of which $533 related to the pre-tax gain from the $600 proceeds from the sale and $544 related to the Company’s remaining 50% investment in the joint venture being remeasured to fair value. The after-tax gain was $843 . The fair value is based on the price paid to Eaton for the 50% interest sold to Cummins, Inc. and further supported by a discounted cash flow model. Eaton accounts for its investment on the equity method of accounting.

REVENUE RECOGNITION

REVENUE RECOGNITION	9 Months Ended

Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	REVENUE RECOGNITION Sales are recognized when obligations under the terms of the contract are satisfied and control of promised goods or services have transferred to our customers. Sales are measured at the amount of consideration the Company expects to be paid in exchange for these products or services. The majority of the Company’s sales agreements contain performance obligations satisfied at a point in time when title and risk and rewards of ownership have transferred to the customer. Sales recognized over time are less than 5% of Eaton’s Consolidated Net Sales. Sales recognized over time are generally accounted for using an input measure to determine progress completed at the end of the period. Sales for service contracts generally are recognized as the services are provided. For agreements with multiple performance obligations, judgment is required to determine whether performance obligations specified in these agreements are distinct and should be accounted for as separate revenue transactions for recognition purposes. In these types of agreements, we generally allocate sales price to each distinct obligation based on the price of each item sold in separate transactions. Due to the nature of the work required to be performed for obligations recognized over time, Eaton estimates total costs by contract. The estimate of total costs are subject to judgment. Estimated amounts are included in the recognized sales price to the extent it is not probable that a significant reversal of cumulative sales will occur. Additionally, contracts can be modified to account for changes in contract specifications, requirements or sale price. The effect of a contract modification on the sales price or adjustments to the measure of completion under the input method are recognized as adjustments to revenue on a cumulative catch-up basis. Payment terms vary by the type and location of the customer and the products or services offered. Generally, the time between when revenue is recognized and when payment is due is not significant. Eaton does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year. Sales, value added, and other taxes collected concurrent with revenue are excluded from sales. Shipping and handling costs are treated as fulfillment costs and are included in Cost of products sold. Eaton records reductions to sales for returns, and customer and distributor incentives, primarily comprised of rebates, at the time of the initial sale. Rebates are estimated based on sales terms, historical experience, trend analysis, and projected market conditions in the various markets served. The rebate programs offered vary across businesses due to the numerous markets Eaton serves, but the most common incentives relate to amounts paid or credited to customers for achieving defined volume levels. Returns are estimated at the time of the sale primarily based on historical experience and are recorded gross on the Condensed Consolidated Balance Sheet. Sales commissions are expensed when the amortization period is less than a year and are generally not capitalized as they are typically earned at the completion of the contract when the customer is invoiced or when the customer pays Eaton. Sales of products and services varies by segment and are discussed in Note 15 of Eaton’s 2017 Form 10-K and in Note 14. In the Electrical Products segment, sales contracts are primarily for electrical components, industrial components, residential products, single phase power quality, emergency lighting, fire detection, wiring devices, structural support systems, circuit protection, and lighting products. These sales contracts are primarily based on a customer’s purchase order followed by our order acknowledgement, and may also include a master supply or distributor agreement. In this segment, performance obligations are generally satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility. In the Electrical Systems and Services segment, sales contracts are primarily for power distribution and assemblies, three phase power quality, hazardous duty electrical equipment, intrinsically safe explosion-proof instrumentation, utility power distribution, power reliability equipment, and services. The majority of the sales contracts in this segment contain performance obligations satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility; however, certain power distribution and power quality services are recognized over time. Many of the products and services in power distribution and power quality services meet the definition of continuous transfer of control to customers and are recognized over time. These products are engineered to a customer’s design specifications, have no alternative use to Eaton, and are controlled by the customer as evidenced by the customer’s contractual ownership of the work in process or our right to payment for work performed to date plus a reasonable margin. As control is transferring over time, sales are recognized based on the extent of progress towards completion of the obligation. Eaton generally uses an input method to determine the progress completed and sales are recorded proportionally as costs are incurred. Incurred cost represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. In the Hydraulics segment, sales contracts are primarily for hydraulic components and systems for industrial and mobile equipment. These sales contracts are primarily based on a customer’s purchase order. In this segment, performance obligations are generally satisfied at a point in time when we ship the product from our facility. In the Aerospace segment, sales contracts are primarily for aerospace fuel, hydraulics, and pneumatic systems for commercial and military use. These sales contracts are primarily based on a customer’s purchase order, and frequently covered by terms and conditions included in a long-term agreement. In this segment, performance obligations are generally satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility. Our military contracts are primarily fixed-price contracts that are not subject to performance-based payments or progress payments from the customer. In the Vehicle segment, sales contracts are primarily for drivetrains, powertrain systems and critical components that reduce emissions and improve fuel economy, stability, performance, and safety of cars, light trucks and commercial vehicles. These sales contracts are primarily based on a customer’s purchase order or a blanket purchase order subject to firm releases, frequently covered by terms and conditions included in a master supply agreement. In this segment, performance obligations are generally satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility. In the eMobility segment, sales contracts are primarily for electronic and mechanical components and systems that improves the power management and performance of both on-road and off-road vehicles. These sales contracts are primarily based on a customer’s purchase order. In this segment, performance obligations are generally satisfied at a point in time either when we ship the product from our facility, or when it arrives at the customer’s facility. In limited circumstances, primarily in the Electrical and Vehicle segments, Eaton sells separately-priced warranties that extend the warranty coverage beyond the standard coverage offered on specific products. Sales for these separately-priced warranties are recorded based on their stand-alone selling price and are recognized as revenue over the length of the warranty period. The Company’s six operating segments and the following tables disaggregate sales by lines of businesses, geographic destination, market channel or end market. Three months ended September 30, 2018 Net sales United States Rest of World Total Electrical Products $ 1,055 $ 734 $ 1,789 Electrical Systems and Services 1,000 519 1,519 Hydraulics 301 369 670 Original Equipment Manufacturers Aftermarket, Distribution and End User Aerospace $ 269 $ 209 478 Commercial Passenger and Light Duty Vehicle $ 451 $ 425 876 eMobility 80 Total $ 5,412 Nine months ended September 30, 2018 Net sales United States Rest of World Total Electrical Products $ 3,048 $ 2,279 $ 5,327 Electrical Systems and Services 2,877 1,536 4,413 Hydraulics 907 1,196 2,103 Original Equipment Manufacturers Aftermarket, Distribution and End User Aerospace $ 799 $ 600 1,399 Commercial Passenger and Light Duty Vehicle $ 1,333 $ 1,335 2,668 eMobility 240 Total $ 16,150 The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (revenue recognized exceeds amount billed to the customer), and deferred revenue (advance payments and billings in excess of revenue recognized). Accounts receivables from customers were $3,566 and $3,399 at September 30, 2018 and December 31, 2017, respectively. Amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. These assets and liabilities are reported on the Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period. Unbilled receivables were $91 and $117 at September 30, 2018 and January 1, 2018, respectively, and are recorded in Prepaid expenses and other current assets. The decrease in unbilled receivables was primarily due to billings to customers for amounts previously recognized as revenue, partially offset by revenue recognized and not yet billed. Changes in the deferred revenue liabilities are as follows: Deferred Revenue Balance at January 1, 2018 $ 227 Customer deposits and billings 696 Revenue recognized in the period (676 ) Translation (6 ) Balance at September 30, 2018 $ 241 A significant portion of open orders placed with Eaton are by original equipment manufacturers or distributors. These open orders are not considered firm as they have been historically subject to releases by customers. In measuring backlog of unsatisfied or partially satisfied obligations, only the amount of orders to which customers are firmly committed are included. Using this criterion, total backlog at September 30, 2018 was approximately $5.4 billion . Eaton expects to recognize approximately 88% of this backlog in the next twelve months and the rest thereafter. Impact of new accounting standard In accordance with the new revenue accounting requirements, the impact of the adoption on the financial statement line items within the accompanying financial statements was as follows: Three months ended September 30, 2018 Consolidated Statements of Income As Reported Adjustment Balances without Adoption of ASC 606 Net sales $ 5,412 $ (5 ) $ 5,407 Cost of products sold 3,597 (4 ) 3,593 Income before income taxes 439 (1 ) 438 Income tax expense 23 — 23 Net income 416 (1 ) 415 Net income attributable to Eaton ordinary shareholders $ 416 $ (1 ) $ 415 Nine months ended September 30, 2018 Consolidated Statements of Income As Reported Adjustment Balances without Adoption of ASC 606 Net sales $ 16,150 $ (23 ) $ 16,127 Cost of products sold 10,841 (14 ) 10,827 Income before income taxes 1,698 (9 ) 1,689 Income tax expense 184 (2 ) 182 Net income 1,514 (7 ) 1,507 Net income attributable to Eaton ordinary shareholders $ 1,514 $ (7 ) $ 1,507 September 30, 2018 Condensed Consolidated Balance Sheets As Reported Adjustment Balances without Adoption of ASC 606 Assets Accounts receivable - net $ 4,027 $ 58 $ 4,085 Inventory 2,835 13 2,848 Prepaid expenses and other current assets 500 (105 ) 395 Deferred income taxes 241 (1 ) 240 Liabilities and shareholders’ equity Other current liabilities $ 2,167 $ (30 ) $ 2,137 Eaton shareholders' equity $ 16,789 $ (5 ) $ 16,784

Commitments and Contingencies Disclosure [Abstract]
LEGAL CONTINGENCIES	LEGAL CONTINGENCIES Eaton is subject to a broad range of claims, administrative and legal proceedings such as lawsuits that relate to contractual allegations, tax audits, patent infringement, personal injuries, antitrust matters, and employment-related matters. Eaton is also subject to asbestos claims from historic products which may have contained asbestos. Insurance may cover some of the costs associated with these claims and proceedings. Although it is not possible to predict with certainty the outcome or cost of these matters, the Company believes they will not have a material adverse effect on the consolidated financial statements. In December 2011, Pepsi-Cola Metropolitan Bottling Company, Inc. (“Pepsi”) filed an action against (a) Cooper Industries, LLC, Cooper Industries, Ltd., Cooper Holdings, Ltd., Cooper US, Inc., and Cooper Industries plc (collectively, “Cooper”), (b) M&F Worldwide Corp., Mafco Worldwide Corp., Mafco Consolidated Group LLC, and PCT International Holdings, Inc. (collectively, “Mafco”), and (c) the Pneumo Abex Asbestos Claims Settlement Trust (the “Trust”) in Texas state court. Pepsi alleged that it was harmed by a 2011 settlement agreement (“2011 Settlement”) among Cooper, Mafco, and Pneumo Abex, LLC (“Pneumo,” which prior to the 2011 Settlement was a Mafco subsidiary), which settlement resolved litigation that Pneumo had previously brought against Cooper involving, among other things, a guaranty related to Pneumo’s friction products business. In November 2015, after a Texas court ruled that Pepsi's claims should be heard in arbitration, Pepsi filed a demand for arbitration against Cooper, Mafco, the Trust, and Pneumo. Pepsi subsequently dropped claims against all parties except Cooper. An arbitration under the auspices of the American Arbitration Association commenced in October 2017. Pepsi’s experts opined, among other things, that the value contributed to the Trust for a release of the guaranty was below reasonably equivalent value, and that an inability of Pneumo to satisfy future liabilities could result in plaintiffs suing Pepsi under various theories. Cooper submitted various expert reports and, among other things, Cooper’s experts opined that Pepsi had no basis to seek any damages and that Cooper paid reasonably equivalent value for the release of its indemnity obligations under the guaranty. The arbitration proceedings closed in December 2017. On July 11, 2018, the arbitration panel made certain findings and concluded that the value contributed to the Trust did not constitute reasonably equivalent value, but ordered the parties to recalculate the amount that should have been contributed to the Trust as of the date of the 2011 transaction. Based on the findings made by the panel and the recalculation ordered by the panel, Cooper believed that no additional amount should be contributed. Pepsi argued that an additional $347 should be contributed. Cooper and its expert disagreed with Pepsi’s argument and believed that Pepsi’s recalculation was flawed and failed to comply with the instructions of the panel. On August 23, 2018, the panel issued its final award and ordered Cooper to pay $293 to Pneumo Abex. On August 30, 2018, Pepsi sought to confirm the award in Texas state court, which Cooper opposed on October 9, 2018. Cooper further requested that the court vacate the award on various grounds, including that Cooper was prejudiced by the conduct of the proceedings, the panel exceeded its powers, and because the panel denied Cooper a full and fair opportunity to present certain evidence. The court confirmed the award at the confirmation hearing, which was held on October 12, 2018. The Company is considering its options, including an appeal.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The effective income tax rate for the third quarter and the first nine months of 2018 was expense of 5.2% and 10.8% compared to expense of 17.3% and 13.9% for the third quarter and first nine months of 2017. The tax rate for the third quarter and first nine months of 2018 includes $69 of tax benefit on the arbitration decision expense which was recorded during the third quarter and is discussed in Note 8. The tax rate for the third quarter and first nine months of 2017 includes $234 of tax expense on the gain related to the sale of a business discussed in Note 2, which closed during the third quarter of 2017. Excluding the one -time impacts of the 2018 arbitration decision and the 2017 sale of a business, the effective income tax rate for both the third quarter and first nine months of 2018 was expense of 12.8% compared to expense of 9.6% and 8.9% for the third quarter and first nine months of 2017. The increase in the effective tax rate in the third quarter and first nine months of 2018 was due to greater levels of income in higher tax jurisdictions. The U.S. Tax Cuts and Jobs Act (“TCJA”) was enacted on December 22, 2017 and the Company recorded a provisional tax benefit amount of $62 in the fourth quarter of 2017 for the remeasurement of deferred tax balances, including valuation allowances related to the realization of deferred tax assets, and the one-time transition tax. The Company continues to analyze aspects of the TCJA, including additional regulations and guidance which may impact the provisional amounts recorded for the remeasurement of deferred tax balances and related valuation allowances, and the one-time transition tax. The Company recorded a $17 tax expense adjustment to the 2017 provisional tax amounts in the third quarter of 2018, primarily related to the one-time transition tax, resulting in a cumulative provisional tax benefit amount of $45 related to the enactment of the TCJA. The Company will finalize its accounting for the 2017 tax impact of the TCJA in the fourth quarter of 2018. During the third quarter of 2018, the United States Internal Revenue Service (“IRS”) completed its examination of the consolidated income tax returns of the Company’s United States subsidiaries for tax years 2011 through 2013 and has proposed adjustments to certain transfer pricing tax positions, including adjustments similar to those proposed and previously disclosed for prior audit periods for products manufactured in the Company’s facilities in Puerto Rico and the Dominican Republic and sold to affiliated companies located in the U.S. The IRS also proposed adjustments involving the recognition of income for several of the Company’s controlled foreign corporations, which is the same issue that has been previously disclosed and is currently in litigation for tax years 2007-2010. The Company intends to pursue its administrative appeals alternatives with respect to each of the IRS adjustments and believes that final resolution of the proposed adjustments will not have a material impact on its consolidated financial statements. During 2010, the Company received a tax assessment of $42 (translated at the September 30, 2018 exchange rate), plus interest and penalties, in Brazil for the tax years 2005 through 2008 that relates to the amortization of certain goodwill generated from the acquisition of third-party businesses and corporate reorganizations. On August 31, 2018, the Company received an unfavorable result at the final tax administrative appeals level, resulting in an alleged tax deficiency of $42 plus $128 of interest and penalties (translated at the September 30, 2018 exchange rate). The Company plans to challenge the assessment in the judicial system, which is expected to take up to 10 years to resolve. During 2014, the Company received a tax assessment of $32 (translated at the September 30, 2018 exchange rate), plus interest and penalties, for the 2009 through 2012 tax years (primarily relating to the same issues concerning the 2005 through 2008 tax years), which the Company is also contesting and remains under review at the final tax administrative appeals level. The Company continues to believe that final resolution of both of the assessments will not have a material impact on its consolidated financial statements.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair value is measured based on an exit price, representing the amount that would be received to sell an asset or paid to satisfy a liability in an orderly transaction between market participants. Fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a fair value hierarchy is established, which categorizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. A summary of financial instruments recognized at fair value, and the fair value measurements used, follows: Total Level 1 Level 2 Level 3 September 30, 2018 Cash $ 327 $ 327 $ — $ — Short-term investments 178 178 — — Net derivative contracts (59 ) — (59 ) — December 31, 2017 Cash $ 561 $ 561 $ — $ — Short-term investments 534 534 — — Net derivative contracts 36 — 36 — Eaton values its financial instruments using an industry standard market approach, in which prices and other relevant information is generated by market transactions involving identical or comparable assets or liabilities. No financial instruments were measured using unobservable inputs. Other Fair Value Measurements Long-term debt and the current portion of long-term debt had a carrying value of $7,163 and fair value of $7,137 at September 30, 2018 compared to $7,745 and $8,048 , respectively, at December 31, 2017 . The fair value of Eaton's debt instruments were estimated using prevailing market interest rates on debt with similar creditworthiness, terms and maturities, and are considered a Level 2 fair value measurement.

DERIVATIVE FINANCIAL INSTRUMENT

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES In the normal course of business, Eaton is exposed to certain risks related to fluctuations in interest rates, currency exchange rates and commodity prices. The Company uses various derivative and non-derivative financial instruments, primarily interest rate swaps, currency forward exchange contracts, currency swaps and, to a lesser extent, commodity contracts, to manage risks from these market fluctuations. The instruments used by Eaton are straightforward, non-leveraged instruments. The counterparties to these instruments are financial institutions with strong credit ratings. Eaton maintains control over the size of positions entered into with any one counterparty and regularly monitors the credit rating of these institutions. Such instruments are not purchased and sold for trading purposes. Derivative financial instruments are accounted for at fair value and recognized as assets or liabilities in the Condensed Consolidated Balance Sheets. Accounting for the gain or loss resulting from the change in the fair value of the derivative financial instrument depends on whether it has been designated, and is effective, as part of a hedging relationship and, if so, as to the nature of the hedging activity. Eaton formally documents all relationships between derivative financial instruments accounted for as designated hedges and the hedged item, as well as its risk-management objective and strategy for undertaking the hedge transaction. This process includes linking derivative financial instruments to a recognized asset or liability, specific firm commitment, forecasted transaction, or net investment in a foreign operation. These financial instruments can be designated as: • Hedges of the change in the fair value of a recognized fixed-rate asset or liability, or the firm commitment to acquire such an asset or liability (a fair value hedge); for these hedges, the gain or loss from the derivative financial instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in income during the period of change in fair value. • Hedges of the variable cash flows of a recognized variable-rate asset or liability, or the forecasted acquisition of such an asset or liability (a cash flow hedge); for these hedges, the effective portion of the gain or loss from the derivative financial instrument is recognized in Accumulated other comprehensive loss and reclassified to income in the same period when the gain or loss on the hedged item is included in income. • Hedges of the currency exposure related to a net investment in a foreign operation (a net investment hedge); for these hedges, the effective portion of the gain or loss from the derivative financial instrument is recognized in Accumulated other comprehensive loss and reclassified to income in the same period when the gain or loss related to the net investment in the foreign operation is included in income. The gain or loss from a derivative financial instrument designated as a hedge that is effective is classified in the same line of the Consolidated Statements of Income as the offsetting loss or gain on the hedged item. The change in fair value of a derivative financial instrument that is not effective as a hedge is immediately recognized in income. The cash flows resulting from these financial instruments are classified in operating activities on the Condensed Consolidated Statements of Cash Flows. For derivatives that are not designated as a hedge, any gain or loss is immediately recognized in income. The majority of derivatives used in this manner relate to risks resulting from assets or liabilities denominated in a foreign currency and certain commodity contracts that arise in the normal course of business. Gains and losses associated with commodity hedge contracts are classified in Cost of products sold. Eaton uses certain of its debt denominated in foreign currency to hedge portions of its net investments in foreign operations against foreign currency exposure (net investment hedges). Foreign currency denominated debt designated as non-derivative net investment hedging instruments on an after-tax basis was $88 at September 30, 2018 and $88 at December 31, 2017 , and designated on a pre-tax basis was $631 at September 30, 2018 and $652 at December 31, 2017 . Derivative Financial Statement Impacts The fair value of derivative financial instruments recognized in the Condensed Consolidated Balance Sheets follows: Notional amount Other current assets Other noncurrent assets Other current liabilities Other noncurrent liabilities Type of hedge Term September 30, 2018 Derivatives designated as hedges Fixed-to-floating interest rate swaps $ 2,550 $ 1 $ 16 $ 1 $ 62 Fair value 9 months to 16 years Currency exchange contracts 954 12 2 21 5 Cash flow 1 to 36 months Total $ 13 $ 18 $ 22 $ 67 Derivatives not designated as hedges Currency exchange contracts $ 7,616 $ 33 $ 33 1 to 12 months Commodity contracts 13 — 1 1 to 12 months Total $ 33 $ 34 December 31, 2017 Derivatives designated as hedges Fixed-to-floating interest rate swaps $ 2,965 $ 1 $ 41 $ — $ 17 Fair value 6 months to 17 years Currency exchange contracts 924 7 7 22 2 Cash flow 1 to 36 months Total $ 8 $ 48 $ 22 $ 19 Derivatives not designated as hedges Currency exchange contracts $ 3,719 $ 39 $ 19 1 to 12 months Commodity contracts 13 1 — 1 to 12 months Total $ 40 $ 19 The currency exchange contracts shown in the table above as derivatives not designated as hedges are primarily contracts entered into to manage currency volatility or exposure on intercompany receivables, payables and loans. While Eaton does not elect hedge accounting treatment for these derivatives, Eaton targets managing 100% of the intercompany balance sheet exposure to minimize the effect of currency volatility related to the movement of goods and services in the normal course of its operations. This activity represents the great majority of these currency exchange contracts. For the nine months ended September 30, 2018, $122 of cash outflow resulting from the settlement of these derivatives has been classified in investing activities on the Condensed Consolidated Statement of Cash Flows. The cash flow from the settlement of these derivatives has been presented in operating activities in prior periods and have not been restated as such amounts are not material. The impact of derivative instruments to the Consolidated Statement of Income and Comprehensive Income follow: Gain (loss) recognized in other comprehensive (loss) income Location of gain (loss) reclassified from Accumulated other comprehensive loss Gain (loss) reclassified from Accumulated other comprehensive loss Three months ended Three months ended 2018 2017 2018 2017 Derivatives designated as cash flow hedges Forward starting floating-to-fixed interest rate swaps $ — $ (10 ) Interest expense - net $ — $ — Interest rate locks — (9 ) Interest expense - net — — Currency exchange contracts (12 ) (6 ) Cost of products sold (4 ) (7 ) Total $ (12 ) $ (25 ) $ (4 ) $ (7 ) Gain (loss) recognized in Location of gain (loss) Gain (loss) reclassified Nine months ended Nine months ended 2018 2017 2018 2017 Derivatives designated as cash Forward starting floating-to-fixed $ — $ (15 ) Interest expense - net $ — $ — Interest rate locks — (9 ) Interest expense - net — — Currency exchange contracts (14 ) (5 ) Cost of products sold (12 ) (12 ) Total $ (14 ) $ (29 ) $ (12 ) $ (12 ) Amounts recognized in net income follow: Three months ended Nine months ended 2018 2017 2018 2017 Derivatives designated as fair value hedges Fixed-to-floating interest rate swaps $ (12 ) $ (4 ) $ (71 ) $ (7 ) Related long-term debt converted to floating interest rates by interest rate swaps 12 4 71 7 $ — $ — $ — $ — Gains and losses described above were recognized in Interest expense - net.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	The accompanying unaudited condensed consolidated financial statements of Eaton Corporation plc (Eaton or the Company) have been prepared in accordance with generally accepted accounting principles for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by United States generally accepted accounting principles (US GAAP) for complete financial statements. However, in the opinion of management, all adjustments (consisting of normal recurring accruals) have been made that are necessary for a fair presentation of the condensed consolidated financial statements for the interim periods. This Form 10-Q should be read in conjunction with the consolidated financial statements and related notes included in Eaton’s 2017 Form 10-K. The interim period results are not necessarily indicative of the results to be expected for the full year. Management has evaluated subsequent events through the date this Form 10-Q was filed with the Securities and Exchange Commission. During the first quarter of 2018, Eaton re-segmented certain reportable operating segments due to a reorganization of the Company's businesses. The new reportable business segment is eMobility (which includes certain legacy Electrical Products and Vehicle product lines). See Note 14 for additional information related to these segments.
Reclassifications	Certain prior year amounts have been reclassified to conform to the current year presentation.
Revenue Recognition, Policy	Revenue Recognition Sales are recognized when control of promised goods or services are transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services. The majority of the Company’s sales agreements contain performance obligations satisfied at a point in time when control is transferred to the customer. Sales recognized over time are generally accounted for using an input measure to determine progress completed at the end of the period. Sales for service contracts generally are recognized as the services are provided. For agreements with multiple performance obligations, judgment is required to determine whether performance obligations specified in these agreements are distinct and should be accounted for as separate revenue transactions for recognition purposes. In these types of agreements, we generally allocate sales price to each distinct obligation based on the price of each item sold in separate transactions. Payment terms vary by the type and location of the customer and the products or services offered. Generally, the time between when revenue is recognized and payment is due is not significant. Eaton does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year. Sales, value added, and other taxes collected concurrent with revenue are excluded from sales. Shipping and handling costs are treated as fulfillment costs and are included in Cost of products sold. Eaton records reductions to sales for returns, and customer and distributor incentives, primarily comprised of rebates, at the time of the initial sale. Rebates are estimated based on sales terms, historical experience, trend analysis, and projected market conditions in the various markets served. The rebate programs offered vary across businesses due to the numerous markets Eaton serves, but the most common incentives relate to amounts paid or credited to customers for achieving defined volume levels. Returns are estimated at the time of the sale primarily based on historical experience and recorded gross on the Consolidated Balance Sheet. See Note 4 for additional information.
Adoption of ASU 2014-09	Adoption of New Accounting Standards Eaton adopted Accounting Standard Update 2014-09, Revenue from Contracts with Customers, at the start of the first quarter of 2018 using the modified retrospective approach and recorded a cumulative effect adjustment to retained earnings based on the current terms and conditions for open contracts as of January 1, 2018. The adoption of the standard did not have a material impact on the Company’s Consolidated financial statements. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. Consolidated Balance Sheet Balance at December 31, 2017 Adjustments due to ASU 2014-09 Balance at January 1, 2018 Assets Accounts receivable - net $ 3,943 $ (99 ) $ 3,844 Prepaid expenses and other current assets 679 129 808 Deferred income taxes 253 1 254 Liabilities and shareholders' equity Other current liabilities $ 1,872 $ 33 $ 1,905 Eaton shareholders' equity 17,253 (2 ) 17,251
Adoption of ASU 2016-16	Eaton adopted Accounting Standards Update 2016-16, Intra-Entity Transfers of Assets Other Than Inventory (ASU 2016-16), at the start of the first quarter of 2018. This accounting standard requires companies to recognize the income tax effects of intercompany sales and transfers of assets other than inventory in the period in which the transfer occurs. The previous accounting standard required companies to defer the income tax effects of intercompany transfers of assets by recording a prepaid tax, until such assets were sold to an outside party or otherwise recognized. ASU 2016-16 requires companies to write off any income tax amounts that had been deferred as prepaid taxes from past intercompany transactions, and record deferred tax balances for amounts that have not been recognized, through a cumulative-effect adjustment to retained earnings. Upon adoption, the Company recorded a cumulative-effect adjustment of $199 to reduce retained earnings.
Adoption of ASU 2017-07	Eaton adopted Accounting Standards Update 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (ASU 2017-07), at the start of the first quarter of 2018. The new standard requires companies to present service costs consistent with other employee compensation costs on the income statement and separate from all other elements of pension costs. The retrospective adoption of this standard resulted in an increase in selling and administrative expense with a corresponding decrease in Other expense - net of $2 for the nine months ended September 30, 2018 , and a reduction in selling and administrative expense with a corresponding increase in Other expense - net of $34 for the nine months ended September 30, 2017 .
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncement In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (Topic 842), (ASU 2016-02). This accounting standard requires that a lessee recognize a lease asset and a lease liability on its balance sheet for all leases, including operating leases, with a term greater than 12 months. ASU 2016-02 will require additional disclosures in the notes to the consolidated financial statements and is effective for annual and interim reporting periods beginning after December 15, 2018. The Company plans to adopt the standard, and related amendments, as of the first quarter of 2019 using the optional transition method that allows for a cumulative-effect adjustment to be recorded at adoption, and will not restate prior periods. A project team has been formed to evaluate and implement the new standard. The project team has been collecting and validating the data required to account for leases under the new standard, and continues to test the functionality of a new lease accounting system being developed by a third-party. In addition, the Company is in the process of identifying and implementing the appropriate changes to business processes and controls to support recognition and disclosure under the new standard. Eaton is evaluating the impact of ASU 2016-02 and expects to recognize a significant lease asset and lease liability for operating leases on the Consolidated Balance Sheet, but does not expect a material impact to the Consolidated Statements of Income or Cash Flows.
