THHN is a thermoplastic high-heat-resistant nylon-coated building wire rated for 600 volts and 90 degrees C in both dry and wet environments. The 19-strand configuration provides greater flexibility compared to solid conductors, making it easier to pull through conduit on longer runs. Licensed electricians install this wire in commercial and residential branch circuit wiring, feeder runs, and panel connections where a durable, code-compliant conductor is required.\u003c\/p\u003e\n\u003cp\u003eThis wire is suited for use in conduit installations in residential, commercial, and light industrial settings. Its 8 AWG size carries up to 40 amps at 60 degrees C, 50 amps at 75 degrees C, or 55 amps at 90 degrees C, making it a common choice for branch circuits serving HVAC equipment, subpanels, and similar loads. The 2500-foot reel format reduces the number of splices needed on large jobs and is practical for contractors stocking a service vehicle or supply room.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8 AWG copper conductor with 19-strand configuration for flexible pulling through conduit\u003c\/li\u003e\n  \u003cli\u003e600-volt rating suitable for standard branch circuit and feeder applications\u003c\/li\u003e\n  \u003cli\u003e90 degrees C temperature rating in both dry and wet locations\u003c\/li\u003e\n  \u003cli\u003eBlack PVC insulation with nylon jacket for abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e2500-foot reel reduces job-site splicing on long runs\u003c\/li\u003e\n  \u003cli\u003eAmpacity of 40 amps at 60 degrees C, 50 amps at 75 degrees C, and 55 amps at 90 degrees C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard THHN building wire for use in conduit or raceway installations per NEC requirements for 8 AWG copper branch circuit and feeder wiring.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\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 before making any connections. THHN wire must be installed in conduit or a recognized raceway — it is not rated for direct burial or open-air use without a conduit system. Verify ampacity derating factors when bundling multiple conductors in a single conduit, as required by NEC ampacity tables.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 8 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStranding\u003c\/strong\u003e: 19 Strand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpacity\u003c\/strong\u003e: 40 amps at 60 degrees C, 50 amps at 75 degrees C, 55 amps at 90 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 90 degrees C (Dry\/Wet)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: Nylon\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: 2500 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.216 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 66 pounds per 1000 feet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: thhn8strblk2500r\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51268390814002,"sku":"THHN8STRBLK2500R","price":1054.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908608.jpg?v=1780703756","url":"https:\/\/voomisupply.com\/products\/thhncu-generic-thhn8strblk2500r-thhn-8-awg-copper-wire-2500ft","provider":"Voomi Supply","version":"1.0","type":"link"}
