Organization, Consolidation and Presentation of Financial Statements [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The unaudited financial statements of Encore Wire Corporation (the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete annual financial statements. In the opinion of management, all adjustments, consisting only of normal recurring adjustments considered necessary for a fair presentation, have been included. Results of operations for interim periods presented do not necessarily indicate the results that may be expected for the entire year. These financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. In March 2020, the World Health Organization declared COVID-19 a global pandemic and recommended containment and mitigation measures worldwide. The Company has not experienced a material impact on its business or its liquidity on account of COVID-19 and is unable to predict any reemergence of any outbreak or its potential long-term impact on our business. Revenue Recognition Our revenue is derived by fulfilling customer orders for the purchase of our products, which include electrical building wire and cable. We recognize revenue at the point in time that control of the ordered products is transferred to the customer, which is typically upon shipment to the customer from our manufacturing facilities and based on agreed upon shipping terms on the related purchase order. Amounts billed and due from our customers are classified as accounts receivables on the balance sheet and require payment on a short-term basis through standard payment terms. Revenue is measured as the amount of consideration we expect to receive in exchange for fulfilling product orders. The amount of consideration we expect to receive and revenue we recognize includes estimates for trade payment discounts and customer rebates which are estimated using historical experience and other relevant factors and is recorded within the same period that the revenue is recognized. We review and update these estimates regularly and the impact of any adjustments are recognized in the period the adjustments are identified. The adjustments resulting from updated estimates of trade payment discounts and customer rebates were not material. Recent Accounting Pronouncements The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the sole source of authoritative U.S. GAAP, along with the Securities and Exchange Commission (“SEC”) and Public Company Accounting Oversight Board (“PCAOB”) issued rules and regulations that apply only to SEC registrants. The FASB issues an Accounting Standard Update (“ASU”) to communicate changes to the codification. The Company considers the applicability and impact of all ASUs. No new standards have been adopted in 2023.

Inventory Disclosure [Abstract]
Inventories	INVENTORIES Inventories are stated at the lower of cost, determined by the last-in, first-out (LIFO) method, or market. Inventories consist of the following: In Thousands March 31, 2023 December 31, 2022 Raw materials $ 74,455 $ 69,567 Work-in-process 68,458 42,611 Finished goods 152,779 138,943 Total Inventory at FIFO cost 295,692 251,121 Adjust to LIFO cost (121,814) (97,934) Inventory, net $ 173,878 $ 153,187 Inventories are stated at the lower of cost, using the last-in, first out (“LIFO”) method, or market. The Company maintains two inventory pools for LIFO purposes. As permitted by U.S. GAAP, the Company maintains its inventory costs and cost of goods sold on a first-in, first-out (“FIFO”) basis and makes a monthly adjustment to adjust total inventory and cost of goods sold from FIFO to LIFO. The Company applies the lower of cost or market (“LCM”) test by comparing the LIFO cost of its raw materials, work-in-process and finished goods inventories to estimated market values, which are based primarily upon the most recent quoted market price of copper and other material prices as of the end of each reporting period. The Company performs a lower of cost or market calculation quarterly. As of March 31, 2023, no LCM adjustment was required. However, decreases in copper and other material prices could necessitate establishing an LCM reserve in future periods. Additionally, future reductions in the quantity of inventory on hand could cause copper or other raw materials that are carried in inventory at costs different from the cost of copper and other raw materials in the period in which the reduction occurs to be included in costs of goods sold for that period at the different price.

In all periods, the differences between the provisions for income taxes and the income taxes computed using the federal income tax statutory rate are due primarily to the incremental taxes accrued for state and local taxes and the Section 162(m) limitation on executive compensation.

Debt Disclosure [Abstract]
Debt	DEBT On February 9, 2021, the Company terminated its previous credit agreement and entered into a new Credit Agreement (the “2021 Credit Agreement”) with two banks, Bank of America, N.A., as administrative agent and letter of credit issuer, and Wells Fargo Bank, National Association, as syndication agent. The 2021 Credit Agreement extends through February 9, 2026 and provides for maximum borrowings of $200.0 million. At our request, and subject to certain conditions, the commitments under the 2021 Credit Agreement may be increased by a maximum of up to $100.0 million as long as existing or new lenders agree to provide such additional commitments. The 2021 Credit Agreement contains provisions to replace LIBOR with a replacement rate as described in the 2021 Credit Agreement. On October 20, 2022, the Company entered into the First Amendment to the 2021 Credit Agreement (the "Amended 2021 Credit Agreement") which replaced LIBOR with BSBY as permitted under the 2021 Credit Agreement. Borrowings under the line of credit bear interest, at the Company’s option, at either (1) BSBY plus a margin that varies from 1.000% to 1.875% depending upon the Leverage Ratio (as defined in the 2021 Credit Agreement), or (2) the base rate (which is the highest of the federal funds rate plus 0.5%, the prime rate, or BSBY plus 1.0%) plus 0% to 0.375% (depending upon the Leverage Ratio). A commitment fee ranging from 0.200% to 0.325% (depending upon the Leverage Ratio) is payable on the unused line of credit. As of March 31, 2023, there were no borrowings outstanding under the Amended 2021 Credit Agreement, and letters of credit outstanding in the amount of $0.4 million left $199.6 million of credit available under the Amended 2021 Credit Agreement. Obligations under the Amended 2021 Credit Agreement are the only contractual borrowing obligations or commercial borrowing commitments of the Company. The foregoing description of the Amended 2021 Credit Agreement is not complete and is qualified in its entirety by reference to the full text of the Amended 2021 Credit Agreement (filed as Exhibit 10.1 to the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2022, and incorporated herein by reference). Obligations under the Amended 2021 Credit Agreement are unsecured and contain customary covenants and events of default. The Company was in compliance with the covenants as of and for the period ended March 31, 2023.
