Constructed with a 19-strand copper conductor, PVC thermoplastic insulation, and an outer nylon jacket, this wire is sized for branch circuit and feeder runs where a reliable, code-compliant conductor is required. Current capacity is 40 amps at 60 degrees C, 50 amps at 75 degrees C, and 55 amps at 90 degrees C. Electricians use this wire in conduit for residential, commercial, and light industrial wiring applications. It is sold cut to length to reduce waste on the job.\u003c\/p\u003e\u003cp\u003eThis wire is suited for installation inside conduit systems in residential and commercial construction, service panels, subpanel feeders, motor circuits, and general branch circuit wiring. The black insulation color is standard for hot conductors in single-phase and three-phase systems. Cut-to-length purchasing is practical for service calls, panel work, or smaller conduit runs where a full reel is not warranted. A licensed electrician should pull, terminate, and inspect all installations per applicable NEC requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8 AWG stranded copper conductor with 19-strand configuration for flexibility in conduit pulls\u003c\/li\u003e\n\u003cli\u003ePVC thermoplastic insulation with nylon jacket meets THHN designation requirements\u003c\/li\u003e\n\u003cli\u003eRated 600 volts for standard branch circuit and feeder applications\u003c\/li\u003e\n\u003cli\u003e90 degrees C dry temperature rating with ampacity up to 55 amps\u003c\/li\u003e\n\u003cli\u003eBlack insulation color for standard hot-conductor identification\u003c\/li\u003e\n\u003cli\u003eSold cut to length to minimize material waste on smaller jobs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard THHN-rated building wire for use in conduit on residential and commercial electrical systems where 8 AWG copper conductors are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit and verify zero voltage at the panel before pulling or terminating conductors. This wire must be installed inside an approved conduit or raceway and is not rated for direct burial or wet locations without additional protection. Use appropriate wire-pulling lubricant and correct conduit fill calculations to avoid insulation damage during the pull.\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: 8 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 Thermoplastic\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: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 Volt\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\u003eTemperature Rating\u003c\/strong\u003e: 90 degrees C (Dry)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 213 mil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 63 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: thhn8strblkmr\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51268176904498,"sku":"THHN8STRBLKMR","price":1011.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908521.jpg?v=1780701317","url":"https:\/\/voomisupply.com\/products\/thhncu-generic-thhn8strblkmr-8-awg-thhn-stranded-copper-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
