Basis of Presentation and Responsibility for Interim Financial Statements	3 Months Ended

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 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. Basis of presentation The accompanying unaudited condensed consolidated 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 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 for the year ended December 31, 2019. Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Additionally, in March 2020, the World Health Organization declared novel coronavirus 2019 (“COVID-19”) a pandemic. The broader implication of COVID-19 on our results of operations and overall financial performance remains uncertain. We may experience constrained supply or reduced customer demand that could materially adversely impact our business, financial condition, results of operations and overall financial performance in future periods. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year. Adoption of new accounting standards In March 2020, the SEC amended Rule 3-10 of Regulation S-X regarding financial disclosure requirements for registered debt offerings involving subsidiaries as either issuers or guarantors. This amended rule narrows the circumstances that require separate financial statements or summarized financial disclosures of subsidiary issuers and guarantors and simplifies the summarized disclosures required in lieu of those statements. As a result of this amended rule, we have included narrative disclosures in lieu of separate financial statements and summarized financial disclosures

Restructuring and Related Activities [Abstract]

Restructuring

During the three months ended March 31, 2020 and the year ended December 31, 2019, we initiated and continued execution of certain business restructuring initiatives aimed at reducing our fixed cost structure and realigning our business. Specifically in the first three months of 2020, the initiatives were executed primarily in response to the decrease in expected demand attributed to the effect of the COVID-19 pandemic and significant decline in oil and gas prices. Initiatives during the three months ended March 31, 2020 included the reduction in hourly and salaried headcount of approximately 100 employees.

Restructuring related costs included in Selling, general and administrative expense in the Condensed Consolidated Statements of Income and Comprehensive Income included costs for severance and other restructuring costs as follows:

Business Combinations [Abstract]
Acquisitions	On August 30, 2019, we completed the acquisition of Eldon Holding AB ("Eldon") for $127.8 million, net of cash acquired. Eldon, now part of our Enclosures segment, is an innovative European based manufacturer of enclosures that protect sensitive electrical, electronic and data and telecommunications components. The excess purchase price over tangible net assets and identified intangible assets acquired has been preliminarily allocated to goodwill in the amount of $45.6 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, primarily related to the impacts associated with income taxes and other accruals, and may require significant adjustments to arrive at the final purchase price allocation. Eldon's net sales for the quarter ended March 31, 2020 were $26.2 million. On February 10, 2020, we acquired substantially all of the assets of WBT LLC ("WBT") for approximately $30.0 million in cash, subject to purchase price adjustments and a holdback. The U.S. based WBT business manufactures high-quality cable tray systems that will be marketed as part of the nVent CADDY product line within our Electrical & Fastening Solutions segment and nVent HOFFMAN product line within our Enclosures segment. The excess purchase price over tangible net assets and identified intangible assets acquired has been preliminarily allocated to goodwill in the amount of $13.9 million, substantially all of which is expected to be deductible for income tax purposes. Identifiable intangible assets acquired included $11.3 million of definite-lived customer relationships with an estimated useful life of 12 years. The pro forma impact of these acquisitions is not material.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Financial Instruments

Derivative financial instruments

We are exposed to market risk related to changes in foreign currency exchange rates. To manage the volatility related to this exposure, we periodically enter into a variety of derivative financial instruments. Our objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. 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

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 in net earnings and cash flows associated with changes in foreign currency rates. The majority of our foreign currency contracts have an original maturity date of less than one year.

At March 31, 2020 and December 31, 2019, we had outstanding foreign currency derivative contracts with gross notional U.S. dollar equivalent amounts of $27.4 million and $34.5 million, respectively. The impact of these contracts on the Condensed Consolidated Statements of Income and Comprehensive Income was not material for any period presented.

Cross currency swaps

At both March 31, 2020 and December 31, 2019, we had outstanding cross currency swap agreements with a combined notional amount of $303.5 million. The agreements are accounted for as either cash flow hedges, to hedge foreign currency fluctuations on certain intercompany debt, or as net investment hedges, to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. At March 31, 2020 and December 31, 2019, we had deferred foreign currency gains of $18.9 million and $1.9 million, respectively, in Accumulated other comprehensive loss associated with our cross currency swap activity.

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 valued at net asset value ("NAV"), which is based on the fair value of underlying securities owned by the fund divided by the number of shares outstanding.

The recorded amounts and estimated fair values of total debt, excluding unamortized issuance costs and discounts, were as follows:


	March 31, 2020						December 31, 2019
In millions	Recorded Amount		Fair Value		Recorded Amount		Fair Value

Senior notes

In March 2018, nVent Finance S.à r.l. (“nVent Finance” or "Subsidiary Issuer"), a 100-percent owned subsidiary of nVent, issued $300.0 million aggregate principal amount of 3.950% senior notes due 2023 (the "2023 Notes") and $500.0 million aggregate principal amount of 4.550% senior notes due 2028 (the "2028 Notes" and, collectively with the 2023 Notes, the "Notes"). Interest on the Notes is payable semi-annually in arrears on April 15 and October 15 of each year.

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. None of the assets of nVent or its subsidiaries represents 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.

In March 2020, as a proactive measure to maximize our liquidity in response to the effect of the COVID-19 pandemic, we drew down $150.0 million on our Revolving Credit Facility. The proceeds will be available to be used for working capital, general corporate or other purposes. Total availability under the Revolving Credit Facility was $315.4 million as of March 31, 2020.

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 March 31, 2020, we were in compliance with all financial covenants in our debt agreements, and there is no material uncertainty about our ongoing ability to meet those covenants.

Debt outstanding, excluding unamortized issuance costs and discounts, at March 31, 2020 matures on a calendar year basis as follows:

Income Taxes	Mar. 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	The effective income tax rate for the three months ended March 31, 2020 was 62.5%, compared to 14.7% for the three months ended March 31, 2019. The liability for uncertain tax positions was $19.5 million and $17.0 million at March 31, 2020 and December 31, 2019, respectively. We record penalties and interest related to unrecognized tax benefits in Provision for income taxes and Net interest expense, respectively, on the Condensed Consolidated Statements of Income and Comprehensive Income, which is consistent with our past practices. Valuation allowances are recorded to reduce the amount of deferred tax assets in jurisdictions where, based on the weight of information available to us, we determine that it is more likely than not the related tax benefits will not be realized. In the three-month period ended March 31, 2020, as a result of the assessment of the available information, we established a valuation allowance of $19.4 million on certain foreign deferred tax assets. In April 2020, the U.S. Treasury finalized regulations which limit the availability of certain tax deductions we currently claim related to interest expense (the “Regulations”), and those Regulations have retroactive effect to January 1, 2019. Based on the effective timing of the Regulations, we expect to record a non-recurring tax expense of approximately $6 million during the second quarter (period of enactment) to account for the retrospective impact of the Regulations.

Leases [Abstract]

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 months ended March 31, 2020 and March 31, 2019, rent expense was $5.1 million and $4.2 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 were as follows:

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 March 31, 2020 and December 31, 2019 was not 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 March 31, 2020 and December 31, 2019, the outstanding value of bonds, letters of credit and bank guarantees totaled $67.5 million and $70.0 million, respectively.
