The conductor is made from bare copper with 19-strand construction for flexibility during pull-through and termination. Insulation is PVC with a nylon jacket, meeting the THHN designation for thermoplastic high heat-resistant nylon-coated wire. The brown color coding supports standard circuit identification on multi-wire branch circuits. This wire is rated at 600 volts and carries a 20-amp current rating across the 60, 75, and 90 degree C temperature ranges in dry applications.\u003c\/p\u003e\u003cp\u003eThis wire is suited for branch circuit wiring, feeder runs, and control wiring in conduit installations across residential, commercial, and light industrial settings. It is commonly pulled through EMT, rigid metal conduit, PVC conduit, and wireways. The 500-foot spool format supports full branch circuit runs and panel feeder work without mid-run splices. Electricians use brown THHN 12 AWG for the second or third hot leg identification in multi-wire branch circuits and three-phase applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12 AWG bare copper conductor with 19-strand construction for pull flexibility\u003c\/li\u003e\n\u003cli\u003ePVC insulation with nylon outer jacket meeting THHN specifications\u003c\/li\u003e\n\u003cli\u003eRated 600 volts and 20 amps across 60, 75, and 90 degrees C temperature ranges\u003c\/li\u003e\n\u003cli\u003e90 degrees C dry rating and 75 degrees C wet rating for versatile conduit use\u003c\/li\u003e\n\u003cli\u003eBrown insulation color for standard hot-leg circuit identification\u003c\/li\u003e\n\u003cli\u003e500-foot spool length reduces splice points on longer runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in conduit or raceway installations where THHN or THWN-2 dual-rated building wire is required per NEC guidelines for branch circuit and feeder wiring.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit or panel before making any connections. Wire must be installed in a listed conduit or raceway system — THHN is not rated for direct burial or exposed outdoor use without conduit protection. Verify ampacity derating requirements when bundling multiple current-carrying conductors in a single conduit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Size\u003c\/strong\u003e: 12 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStranding\u003c\/strong\u003e: 19 Strand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: PVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 20 amps (60\/75\/90 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 90 degrees C dry, 75 degrees C wet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: THHN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 500 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 26 pounds per 1000 feet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: THHNCU-GENERIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: thhn12strbrn500r\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51268134764850,"sku":"THHN12STRBRN500R","price":345.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908354.jpg?v=1780699979","url":"https:\/\/voomisupply.com\/products\/thhncu-generic-thhn12strbrn500r-thhn-12-awg-copper-wire-500-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
