Accounting Policies [Abstract]
Basis of Presentation and Responsibility for Interim Financial Statements	Basis of Presentation and Responsibility for Interim Financial Statements Business nVent Electric plc ("nVent," "we," "us," "our" or the "Company") is a leading global provider of electrical connection and protection solutions. The Company is comprised of three reporting segments: Enclosures, Thermal Management and Electrical & Fastening Solutions. The Company was incorporated in Ireland on May 30, 2017. Although our jurisdiction of organization is Ireland, we manage our affairs so that we are centrally managed and controlled in the United Kingdom (the "U.K.") and therefore have tax residency in the U.K. Separation from Pentair On April 30, 2018, Pentair plc ("Pentair" or "former Parent") completed the separation of its Water business and its Electrical business into two independent, publicly-traded companies (the "separation"). To effect the separation, Pentair distributed to its shareholders one ordinary share of nVent for every ordinary share of Pentair held as of the record date of April 17, 2018. As a result of the distribution, nVent is an independent publicly-traded company and began "regular way" trading under the symbol "NVT" on the New York Stock Exchange on May 1, 2018. Except where indicated, references below to transactions completed by nVent prior to April 30, 2018 refer to transactions completed by or on behalf of the Electrical reporting segment of Pentair that are reflected on the condensed consolidated and combined financial statements of nVent. Basis of presentation The accompanying unaudited condensed consolidated and combined financial statements of nVent have been prepared following the requirements of the Securities and Exchange Commission ("SEC") for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America ("GAAP") can be condensed or omitted. We are responsible for the unaudited condensed consolidated and combined financial statements included in this document. The financial statements include all normal recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. As these are condensed financial statements, one should also read our consolidated and combined financial statements and notes thereto, which are included in our Annual Report on Form 10-K/A for the year ended December 31, 2018. Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year. The financial statements for periods prior to April 30, 2018 were prepared on a stand-alone basis derived from the consolidated financial statements and records of Pentair as if nVent were operated on a stand-alone basis. These condensed consolidated and combined financial statements have been prepared in U.S. dollars and in accordance with GAAP. Cost allocations For periods prior to the separation, the condensed consolidated and combined financial statements of nVent include general corporate expenses of the former Parent for certain support functions that were provided on a centralized basis, such as expenses related to executive management, finance, audit, legal, information technology, human resources, communications, facilities and employee benefits and compensation. These general corporate expenses are included in the Condensed Consolidated and Combined Statements of Income and Comprehensive Income within Selling, general and administrative expense and Other expense . The amount allocated was $42.5 million for the nine months ended September 30, 2018 , of which $10.3 million was historically recorded to the Electrical segment in Pentair’s consolidated financial statements. These expenses were allocated to nVent on the basis of direct usage when identifiable, with the remainder allocated based on a proportional basis of net sales, headcount or other measures. The Company considers the allocation methodology regarding general corporate expenses of the former Parent to be reasonable for all periods presented. Nevertheless, the condensed consolidated and combined financial statements of nVent for periods prior to the separation may not reflect the actual expenses that would have been incurred and may not reflect nVent’s condensed consolidated and combined results of operations, financial position and cash flows had it been a stand-alone company during the periods presented. Actual costs for periods prior to the separation that would have been incurred if nVent had been a stand-alone company would depend on multiple factors including organization structure, capital structure and strategic decisions made in various areas, including information technology and infrastructure. Transactions between nVent and the former Parent have been included in related party transactions in these unaudited condensed consolidated and combined financial statements and were considered to be effectively settled at the time the transaction was recorded. The total net effect of the settlement of these transactions is reflected in the Condensed Consolidated and Combined Statements of Cash Flows as a financing activity. For periods prior to the separation, certain nVent operations were included in the former Parent’s U.S. federal and state income tax returns, and substantially all income taxes on those operations have been paid by the former Parent. Income tax expense and other income tax related information contained in these condensed consolidated and combined financial statements for periods prior to the separation are presented on a separate return approach as if nVent filed its own tax returns. Under this approach, the provision for income taxes represented income tax paid or payable (or received or receivable) plus the change in deferred taxes during the year calculated as if nVent was a stand-alone taxpayer filing hypothetical income tax returns where applicable. Adoption of new accounting standards On January 1, 2019, we adopted ASU No. 2016-02, “Leases” and did not recast comparative periods in transition to the new standard. In addition, we elected the package of practical expedients permitted under the transition guidance, which among other things, allowed us to carry forward the historical lease classification. We also elected the practical expedient to not separate non-lease components from lease components for all leases. Accordingly, all costs associated with a lease contract are accounted for as lease cost. In addition, we did not elect to apply the hindsight practical expedient. We implemented internal controls and key system functionality to enable the preparation of financial information upon adoption. Refer to Note 13 for more information regarding leases. On January 1, 2018, we adopted ASU No. 2014-09, "Revenue from Contracts with Customers" and the related amendments ("ASC 606" or "the new revenue standard") using the modified retrospective method. As a result of adoption, the cumulative impact to our beginning equity at January 1, 2018 was $1.8 million . The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. We expect the impact of the adoption of the new standard to be immaterial to our net income on an ongoing basis. The adoption of the new standard had an impact on our accounting for certain custom products manufactured by our Enclosures segment. Prior to the adoption of the standard revenue was recognized for these custom products upon shipment. However, as these products have no alternative use to the Company and we have an enforceable right to payment for our performance completed to date, revenue related to these custom products will be recognized over time. Additionally, the new revenue standard resulted in reclassifications on the Condensed Consolidated Balance Sheets related to accounting for sales returns. On January 1, 2018, we adopted ASU No. 2016-16, "Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory" using the modified retrospective method. The ASU requires the tax effects of all intra-entity sales of assets other than inventory to be recognized in the period in which the transaction occurs. The adoption resulted in a $174.5 million cumulative-effect adjustment recorded in equity as of the beginning of 2018 that reflects a $201.5 million reduction of non-current prepaid income tax assets, partially offset by the establishment of $27.0 million of deferred tax assets. The cumulative effect of the changes made to our January 1, 2018 Condensed Combined Balance Sheets from the modified retrospective adoption of ASU 2016-16 and ASU 2014-09 was as follows: Condensed Combined Balance Sheets In millions Balance at December 31, 2017 Adjustments due to ASU 2016-16 Adjustments due to ASU 2014-09 Balance at January 1, 2018 Assets Accounts and notes receivable, net $ 349.3 $ — $ 3.8 $ 353.1 Inventories 224.1 — (1.8 ) 222.3 Other current assets 132.3 — 1.8 134.1 Other non-current assets 251.8 (174.5 ) — 77.3 Liabilities Other current liabilities 141.3 — 3.8 145.1 Deferred tax liabilities 279.4 — 0.4 279.8 Equity Net Parent investment 3,848.4 (174.5 ) 1.8 3,675.7

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Revenue recognition Revenue is recognized when control of the promised goods or services are transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for transferring those goods or providing services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. When determining whether the customer has obtained control of the goods or services, we consider any future performance obligations. Generally, there is no post-shipment obligation on product sold other than warranty obligations in the normal and ordinary course of business. In the event significant post-shipment obligations were to exist, revenue recognition would be deferred until nVent has substantially accomplished what it must do to be entitled to the benefits represented by the revenues. Performance obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. For contracts with multiple performance obligations, stand-alone selling price is generally readily observable. Our performance obligations are satisfied at a point in time or over time as work progresses. Revenue from products and services transferred to customers at a point in time accounted for 74% and 73% of our revenue for the three-month periods ended September 30, 2019 and 2018 , respectively, and 73% and 72% of our revenue for the nine-month periods ended September 30, 2019 and 2018 , respectively. Revenue on these contracts is recognized when obligations under the terms of the contract with our customer are satisfied; generally this occurs with the transfer of control upon shipment. Revenue from products and services transferred to customers over time accounted for 26% and 27% of our revenue for the three-month periods ended September 30, 2019 and 2018 , respectively, and 27% and 28% of our revenue for the nine-month periods ended September 30, 2019 and 2018, respectively. For the majority of our revenue recognized over time, we use an input measure to determine progress towards completion. Under this method, sales and gross profit are recognized as work is performed generally based on the relationship between the actual costs incurred and the total estimated costs at completion ("the cost-to-cost method") or based on efforts for measuring progress towards completion in situations in which this approach is more representative of the progress on the contract than the cost-to-cost method. Contract costs include labor, material, overhead and, when appropriate, general and administrative expenses. Changes to the original estimates may be required during the life of the contract and such estimates are reviewed on a regular basis. Sales and gross profit are adjusted using the cumulative catch-up method for revisions in estimated total contract costs. These reviews have not resulted in adjustments that were significant to our results of operations. For performance obligations related to long-term contracts, when estimates of total costs to be incurred on a performance obligation exceed total estimates of revenue to be earned, a provision for the entire loss on the performance obligation is recognized in the period the loss is determined. We use an output method to measure progress towards completion for certain of our Enclosures businesses, as this method appropriately depicts performance towards satisfaction of the performance obligation. Under the output method, revenue is recognized based on number of units produced. On September 30, 2019 , we had $92.0 million of remaining performance obligations on contracts with an original expected duration of one year or more. We expect to recognize the majority of our remaining performance obligations on these contracts within the next 12 to 18 months. Sales returns The right of return may exist explicitly or implicitly with our customers. Our return policy allows for customer returns only upon our authorization. Goods returned must be product we continue to market and must be in salable condition. When the right of return exists, we adjust the transaction price for the estimated effect of returns. We estimate the expected returns based on historical sales levels, the timing and magnitude of historical sales return levels as a percent of sales, type of product, type of customer and a projection of this experience into the future. Pricing and sales incentives Our sales contracts may give customers the option to purchase additional goods or services priced at a discount. Options to acquire additional goods or services at a discount can come in many forms, such as customer programs and incentive offerings including pricing arrangements, promotions and other volume-based incentives. We reduce the transaction price for certain customer programs and incentive offerings including pricing arrangements, promotions and other volume-based incentives that represent variable consideration. Sales incentives given to our customers are recorded using either the expected value method or most likely amount approach for estimating the amount of consideration to which nVent shall be entitled. The expected value is the sum of probability-weighted amounts in a range of possible consideration amounts. An expected value is an appropriate estimate of the amount of variable consideration when there are a large number of contracts with similar characteristics. The most likely amount is the single most likely amount in a range of possible consideration amounts (that is, the single most likely outcome of the contract). The most likely amount is an appropriate estimate of the amount of variable consideration if the contract has limited possible outcomes (for example, an entity either achieves a performance bonus or does not). Pricing is established at or prior to the time of sale with our customers, and we record sales at the agreed-upon net selling price. However, certain of our businesses allow customers to apply for a refund of a percentage of the original purchase price if they can demonstrate sales to a qualifying end customer. We use the expected value method to estimate the anticipated refund to be paid based on historical experience and reduce sales for the probable cost of the discount. The cost of these refunds is recorded as a reduction of transaction price. Volume-based incentives involve rebates that are negotiated at or prior to the time of sale with the customer and are redeemable only if the customer achieves a specified cumulative level of sales or sales increase. Under these incentive programs, at the time of sale, we estimate the anticipated rebate to be paid based on forecasted sales levels. These forecasts are updated at least quarterly for each customer and the transaction price is reduced for the anticipated cost of the rebate. If the forecasted sales for a customer changes, the accrual for rebates is adjusted to reflect the new amount of rebates expected to be earned by the customer. Shipping and handling costs Amounts billed to customers for shipping and handling activities after the customer obtains control are treated as a promised service performance obligation and recorded in Net sales in the accompanying Condensed Consolidated and Combined Statements of Income and Comprehensive Income. Shipping and handling costs incurred by nVent for the delivery of goods to customers are considered a cost to fulfill the contract and are included in Cost of goods sold in the accompanying Condensed Consolidated and Combined Statements of Income and Comprehensive Income. Contract assets and liabilities Contract assets consist of unbilled amounts resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, such as when the customer retains a small portion of the contract price until completion of the contract. We typically receive interim payments on sales under long-term contracts as work progresses, although for some contracts, we may be entitled to receive an advance payment. Contract liabilities consist of advanced payments and billings in excess of costs incurred and deferred revenue. Contract assets are recorded within Other current assets and contract liabilities are recorded within Other current liabilities in the Condensed Consolidated Balance Sheets. Contract assets and liabilities consisted of the following: In millions September 30, 2019 December 31, 2018 $ Change % Change Contract assets $ 65.5 $ 74.4 $ (8.9 ) (12.0 )% Contract liabilities 15.0 13.2 1.8 13.6 % Net contract assets $ 50.5 $ 61.2 $ (10.7 ) (17.5 )% The $10.7 million decrease in net contract assets from December 31, 2018 to September 30, 2019 was primarily the result of timing of milestone payments. The majority of our contract liabilities at December 31, 2018 were recognized in revenue during the nine months ended September 30, 2019 . There were no impairment losses recognized on our contract assets for the three months or nine months ended September 30, 2019 . Practical expedients and exemptions We generally expense incremental costs of obtaining a contract when incurred because the amortization period would be less than one year. These costs primarily relate to sales commissions and are recorded in Selling, general and administrative expense in the Condensed Consolidated and Combined Statements of Income and Comprehensive Income. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. Further, we do not adjust the promised amount of consideration for the effects of a significant financing component if we expect, at contract inception, that the period between when we transfer a promised good or service to a customer and when the customer pays for that good or service will be one year or less. Revenue by category We disaggregate our revenue from contracts with customers by geographic location and vertical for each of our segments, as we believe these best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors.

Acquisitions	Acquisitions On August 30, 2019 , as part of our Enclosures segment, we completed the acquisition of Eldon Holding AB ("Eldon") for $127.8 million , net of cash acquired. Eldon is an innovative European based manufacturer of enclosures that protect sensitive electrical, electronic and data and telecommunications components. The purchase price was funded primarily through borrowings under our Revolving Credit Facility (as defined in Note 9). The excess purchase price over tangible net assets and identified intangible assets acquired has been preliminarily allocated to goodwill in the amount of $54.2 million , none of which is expected to be deductible for income tax purposes. Identifiable intangible assets acquired included $46.7 million of definite-lived customer relationships with an estimated useful life of 17 years. The preliminary purchase price allocation is subject to further refinement and may require significant adjustments to arrive at the final purchase price allocation. Eldon's net sales for the period from the acquisition date to September 30, 2019 were $7.7 million . The pro forma impact of the acquisition is not material.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Financial Instruments	Derivatives and Financial Instruments Derivative financial instruments We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. We manage our economic and transaction exposure to certain market-based risks through the use of foreign currency derivative financial instruments. Our objective in holding these derivatives is to reduce the volatility of net earnings and cash flows associated with changes in foreign currency exchange rates. The majority of our foreign currency contracts have an original maturity date of less than one year. The derivative contracts contain credit risk to the extent that our bank counterparties may be unable to meet the terms of the agreements. The amount of such credit risk is generally limited to the unrealized gains, if any, in such contracts. Such risk is minimized by limiting those counterparties to major financial institutions of high credit quality. Foreign currency contracts At September 30, 2019 and December 31, 2018 , we had outstanding foreign currency derivative contracts with gross notional U.S. dollar equivalent amounts of $250.7 million and $129.0 million , respectively. The impact of these contracts on the Condensed Consolidated and Combined Statements of Income and Comprehensive Income was not material for any period presented. In August 2019, we designated a cross-currency swap with a gross notional U.S. dollar equivalent amount of $133.9 million as a cash flow hedge to offset foreign currency risk associated with financing the Eldon acquisition. The gross notional U.S. dollar equivalent amount of the cash flow hedge is included in the total amount of foreign currency derivative contracts outstanding as of September 30, 2019 , reflected in the preceding paragraph. Gains or losses on foreign currency contracts designated as hedges are reclassified out of Accumulated Other Comprehensive Loss and into Selling, general and administrative expense in the Condensed Consolidated and Combined Statements of Income and Comprehensive Income when the hedged transactions affect earnings. Such reclassifications during the three and nine months ended September 30, 2019 and 2018 were not material. Net investment hedge We have net investments in foreign subsidiaries that are subject to changes in the foreign currency exchange rate. In October 2018, we designated a cross-currency swap with a gross notional U.S. dollar equivalent amount of $69.1 million as a net investment hedge for a portion of our net investment in our Euro denominated subsidiaries. Gains or losses resulting from the change in fair value of the net investment hedge are included as a component of the cumulative translation adjustment account within Accumulated Other Comprehensive Loss and offset gains and losses on the underlying foreign currency exposures. As of September 30, 2019 and December 31, 2018 , the deferred foreign currency activity in Accumulated Other Comprehensive Loss associated with the net investment hedge was not material. Fair value of financial instruments The following methods were used to estimate the fair values of each class of financial instruments: • short-term financial instruments (cash and cash equivalents, accounts and notes receivable, accounts and notes payable and variable-rate debt) — recorded amount approximates fair value because of the short maturity period; • long-term fixed-rate debt, including current maturities — fair value is based on market quotes available for issuance of debt with similar terms, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance; • foreign currency contract agreements — fair values are determined through the use of models that consider various assumptions, including time value, yield curves, as well as other relevant economic measures, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance; and • deferred compensation plan assets (mutual funds, common/collective trusts and cash equivalents for payment of certain non-qualified benefits for retired, terminated and active employees) — fair value of mutual funds and cash equivalents are based on quoted market prices in active markets that are classified as Level 1 in the valuation hierarchy defined by the accounting guidance; fair value of common/collective trusts are based on observable inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance. The recorded amounts and estimated fair values of total debt, excluding unamortized issuance costs and discounts, were as follows: September 30, December 31, In millions Recorded Amount Fair Value Recorded Amount Fair Value Variable rate debt $ 355.8 $ 355.8 $ 147.5 $ 147.5 Fixed rate debt 800.0 861.2 800.0 793.5 Total debt $ 1,155.8 $ 1,217.0 $ 947.5 $ 941.0 Financial assets and liabilities measured at fair value on a recurring basis were as follows: September 30, 2019 In millions Level 1 Level 2 Level 3 Total Recurring fair value measurements Foreign currency contract liabilities $ — $ (0.8 ) $ — $ (0.8 ) Foreign currency contract assets — 13.0 — 13.0 Deferred compensation plan assets 11.8 4.2 — 16.0 Total recurring fair value measurements $ 11.8 $ 16.4 $ — $ 28.2 December 31, 2018 In millions Level 1 Level 2 Level 3 Total Recurring fair value measurements Foreign currency contract liabilities $ — $ (2.6 ) $ — $ (2.6 ) Deferred compensation plan assets 19.1 4.0 — 23.1 Total recurring fair value measurements $ 19.1 $ 1.4 $ — $ 20.5

The Notes are fully and unconditionally guaranteed as to payment by nVent Electric plc ("Parent Company Guarantor"). There are no subsidiaries that guarantee the Notes. The Parent Company Guarantor has no independent assets or operations unrelated to its investments in its consolidated subsidiaries. The Parent Company Guarantor’s only direct subsidiary is the Subsidiary Issuer. The Subsidiary Issuer has no independent assets or operations unrelated to its investments in its consolidated subsidiaries and the issuance of the Notes and other external debt. The Notes constitute general unsecured senior obligations of the Subsidiary Issuer and rank equally in right of payment with all existing and future unsubordinated and unsecured indebtedness and liabilities of the Subsidiary Issuer. The guarantees of the Notes by the Parent Company Guarantor constitute general unsecured obligations of the Parent Company Guarantor and rank equally in right of payment with all existing and future unsubordinated and unsecured indebtedness and liabilities of the Subsidiary Issuer. Subject to certain qualifications and exceptions, the indenture pursuant to which the Notes were issued contains covenants that, among other things, restrict nVent’s, nVent Finance’s and certain subsidiaries’ ability to merge or consolidate with another person, create liens or engage in sale and lease-back transactions. There are no significant restrictions on the ability of nVent to obtain funds from its subsidiaries by dividend or loan and no material assets of nVent or its subsidiaries which represent restricted net assets pursuant to the guidelines established by the SEC. Senior credit facilities In March 2018, nVent Finance entered into a credit agreement with a syndicate of banks providing for a five-year $200.0 million senior unsecured term loan facility (the "Term Loan Facility") and a five-year $600.0 million senior unsecured revolving credit facility (the "Revolving Credit Facility" and, together with the Term Loan Facility, the "Senior Credit Facilities"). We have the option to request to increase the Revolving Credit Facility in an aggregate amount of up to $300.0 million , subject to customary conditions, including the commitment of the participating lenders. As of September 30, 2019 , we had $216.5 million of outstanding borrowings under the Revolving Credit Facility. Total availability under the Revolving Credit Facility was $383.5 million as of September 30, 2019 . Our debt agreements contain certain financial covenants, the most restrictive of which are in the Senior Credit Facilities, including that we may not permit (i) the ratio of our consolidated debt (net of our consolidated unrestricted cash in excess of $5.0 million but not to exceed $250.0 million ) to our consolidated net income (excluding, among other things, non-cash gains and losses) before interest, taxes, depreciation, amortization and non-cash share-based compensation expense ("EBITDA") on the last day of any period of four consecutive fiscal quarters to exceed 3.75 to 1.00 and (ii) the ratio of our EBITDA to our consolidated interest expense for the same period to be less than 3.00 to 1.00 . In addition, subject to certain qualifications and exceptions, the Senior Credit Facilities also contain covenants that, among other things, restrict our ability to create liens, merge or consolidate with another person, make acquisitions and incur subsidiary debt. As of September 30, 2019 , we were in compliance with all financial covenants in our debt agreements. Debt outstanding, excluding unamortized issuance costs and discounts, at September 30, 2019 matures on a calendar year basis as follows: Q4 In millions 2019 2020 2021 2022 2023 2024 Thereafter Total Contractual debt obligation maturities $ 4.3 $ 17.5 $ 20.0 $ 20.0 $ 594.0 $ — $ 500.0 $ 1,155.8

Leases [Abstract]
Leases	Leases We have operating leases for office space, production facilities, distribution centers, warehouses, sales offices, fleet vehicles and equipment. In accordance with our accounting policy, leases with an initial term of 12 months or less are not recognized on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. We elected the practical expedient for all leases to include both lease and non-lease components within our lease assets and lease liabilities. Our lease agreements do not contain any material residual value guarantees, any material bargain purchase options or material restrictive covenants. We have no material sublease arrangements with third parties or lease transactions with related parties. During the three and nine months ended September 30, 2019 , rent expense was $5.0 million and $14.1 million , respectively, primarily related to operating lease costs. Costs associated with short-term leases, variable rent and subleases were immaterial. Our leases have remaining lease terms of one to ten years, some of which include options to extend the leases for up to five years. Renewal options that are reasonably certain to be exercised are included in the lease term. The incremental borrowing rate is used in determining the present value of lease payments, unless an implicit rate is specified. Incremental borrowing rates on a collateralized basis are determined based on the economic environment in which leases are denominated and the lease term. The weighted average remaining lease term and weighted average discount rate as of September 30, 2019 were as follows: September 30, 2019 Weighted average remaining lease term Operating leases 5 years Weighted average discount rate Operating leases 4.1 % Future lease payments under non-cancelable operating leases as of September 30, 2019 were as follows: In millions Remainder of 2019 $ 4.8 2020 16.4 2021 11.0 2022 7.3 2023 4.1 2024 3.3 Thereafter 10.9 Total lease payments 57.8 Less imputed interest (7.1 ) Total reported lease liability $ 50.7 As of September 30, 2019 , we have no material additional operating leases that have not yet commenced. Future minimum lease commitments under non-cancelable operating leases based on accounting standards applicable as of December 31, 2018 were as follows: In millions 2019 $ 16.2 2020 12.6 2021 8.0 2022 5.6 2023 2.7 Thereafter 9.6 Total $ 54.7 Supplemental cash flow information related to operating leases for the nine months ended September 30, 2019 was as follows: Nine months ended In millions September 30, 2019 Cash paid for amounts included in the measurement of lease liabilities: $ 12.9 Lease right-of-use assets obtained in exchange for new lease liabilities: 12.8 Supplemental balance sheet information related to operating leases was as follows: In millions Classification September 30, 2019 January 1, 2019 Assets Lease right-of-use assets Other non-current assets $ 46.5 $ 44.2 Liabilities Current lease liabilities Other current liabilities $ 15.4 $ 13.6 Non-current lease liabilities Other non-current liabilities 35.3 34.8 Total lease liabilities $ 50.7 $ 48.4

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Warranties and guarantees In connection with the disposition of our businesses or product lines, we may agree to indemnify purchasers for various potential liabilities relating to the sold business, such as pre-closing tax, product liability, warranty, environmental, or other obligations. The subject matter, amounts and duration of any such indemnification obligations vary for each type of liability indemnified and may vary widely from transaction to transaction. Generally, the maximum obligation under such indemnifications is not explicitly stated and as a result, the overall amount of these obligations cannot be reasonably estimated. Historically, we have not made significant payments for these indemnifications. We believe that if we were to incur a loss in any of these matters, the loss would not have a material effect on our financial position, results of operations or cash flows. We recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. We provide service and warranty policies on our products. Liability under service and warranty policies is based upon a review of historical warranty and service claim experience. Adjustments are made to accruals as claim data and historical experience warrant. Our liability for service and product warranties as of September 30, 2019 and December 31, 2018 was no t material. Stand-by letters of credit, bank guarantees and bonds In the ordinary course of business, we are required to commit to bonds, letters of credit and bank guarantees that require payments to our customers for any non-performance. The outstanding face value of these instruments fluctuates with the value of our projects in process and in our backlog. In addition, we issue financial stand-by letters of credit primarily to secure our performance to third parties under self-insurance programs. As of September 30, 2019 and December 31, 2018 , the outstanding value of bonds, letters of credit and bank guarantees totaled $63.0 million and $75.8 million , respectively.

Accounting Policies [Abstract]
Cost Allocations	For periods prior to the separation, the condensed consolidated and combined financial statements of nVent include general corporate expenses of the former Parent for certain support functions that were provided on a centralized basis, such as expenses related to executive management, finance, audit, legal, information technology, human resources, communications, facilities and employee benefits and compensation. These general corporate expenses are included in the Condensed Consolidated and Combined Statements of Income and Comprehensive Income within Selling, general and administrative expense and Other expense . The amount allocated was $42.5 million for the nine months ended September 30, 2018 , of which $10.3 million was historically recorded to the Electrical segment in Pentair’s consolidated financial statements. These expenses were allocated to nVent on the basis of direct usage when identifiable, with the remainder allocated based on a proportional basis of net sales, headcount or other measures. The Company considers the allocation methodology regarding general corporate expenses of the former Parent to be reasonable for all periods presented. Nevertheless, the condensed consolidated and combined financial statements of nVent for periods prior to the separation may not reflect the actual expenses that would have been incurred and may not reflect nVent’s condensed consolidated and combined results of operations, financial position and cash flows had it been a stand-alone company during the periods presented. Actual costs for periods prior to the separation that would have been incurred if nVent had been a stand-alone company would depend on multiple factors including organization structure, capital structure and strategic decisions made in various areas, including information technology and infrastructure. Transactions between nVent and the former Parent have been included in related party transactions in these unaudited condensed consolidated and combined financial statements and were considered to be effectively settled at the time the transaction was recorded. The total net effect of the settlement of these transactions is reflected in the Condensed Consolidated and Combined Statements of Cash Flows as a financing activity. For periods prior to the separation, certain nVent operations were included in the former Parent’s U.S. federal and state income tax returns, and substantially all income taxes on those operations have been paid by the former Parent. Income tax expense and other income tax related information contained in these condensed consolidated and combined financial statements for periods prior to the separation are presented on a separate return approach as if nVent filed its own tax returns. Under this approach, the provision for income taxes represented income tax paid or payable (or received or receivable) plus the change in deferred taxes during the year calculated as if nVent was a stand-alone taxpayer filing hypothetical income tax returns where applicable.
New accounting standards	Adoption of new accounting standards On January 1, 2019, we adopted ASU No. 2016-02, “Leases” and did not recast comparative periods in transition to the new standard. In addition, we elected the package of practical expedients permitted under the transition guidance, which among other things, allowed us to carry forward the historical lease classification. We also elected the practical expedient to not separate non-lease components from lease components for all leases. Accordingly, all costs associated with a lease contract are accounted for as lease cost. In addition, we did not elect to apply the hindsight practical expedient. We implemented internal controls and key system functionality to enable the preparation of financial information upon adoption. Refer to Note 13 for more information regarding leases. On January 1, 2018, we adopted ASU No. 2014-09, "Revenue from Contracts with Customers" and the related amendments ("ASC 606" or "the new revenue standard") using the modified retrospective method. As a result of adoption, the cumulative impact to our beginning equity at January 1, 2018 was $1.8 million . The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. We expect the impact of the adoption of the new standard to be immaterial to our net income on an ongoing basis. The adoption of the new standard had an impact on our accounting for certain custom products manufactured by our Enclosures segment. Prior to the adoption of the standard revenue was recognized for these custom products upon shipment. However, as these products have no alternative use to the Company and we have an enforceable right to payment for our performance completed to date, revenue related to these custom products will be recognized over time. Additionally, the new revenue standard resulted in reclassifications on the Condensed Consolidated Balance Sheets related to accounting for sales returns. On January 1, 2018, we adopted ASU No. 2016-16, "Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory" using the modified retrospective method. The ASU requires the tax effects of all intra-entity sales of assets other than inventory to be recognized in the period in which the transaction occurs. The adoption resulted in a $174.5 million cumulative-effect adjustment recorded in equity as of the beginning of 2018 that reflects a $201.5 million reduction of non-current prepaid income tax assets, partially offset by the establishment of $27.0 million of deferred tax assets. The cumulative effect of the changes made to our January 1, 2018 Condensed Combined Balance Sheets from the modified retrospective adoption of ASU 2016-16 and ASU 2014-09 was as follows: Condensed Combined Balance Sheets In millions Balance at December 31, 2017 Adjustments due to ASU 2016-16 Adjustments due to ASU 2014-09 Balance at January 1, 2018 Assets Accounts and notes receivable, net $ 349.3 $ — $ 3.8 $ 353.1 Inventories 224.1 — (1.8 ) 222.3 Other current assets 132.3 — 1.8 134.1 Other non-current assets 251.8 (174.5 ) — 77.3 Liabilities Other current liabilities 141.3 — 3.8 145.1 Deferred tax liabilities 279.4 — 0.4 279.8 Equity Net Parent investment 3,848.4 (174.5 ) 1.8 3,675.7
