Rated for 600 volts and up to 90 degrees C in dry locations, this wire carries up to 475 amps at its top temperature rating. The 61-strand construction provides flexibility during pull-through in conduit runs. It is sold cut to length from a 2500-foot reel, making it suitable for large commercial and industrial feeder applications. Licensed electricians and electrical contractors are the primary installers of wire in this size class.\u003c\/p\u003e\n\u003cp\u003eThis wire is used in commercial, industrial, and heavy residential electrical installations where large-capacity feeder or service-entrance conductors are required. Common applications include main distribution panels, motor feeders, switchgear connections, and large branch circuits. The black insulation color follows standard phase-identification practice in multi-conductor conduit runs. With an outer diameter of 1024 mil, conduit fill calculations must be completed per NEC Table 1 and Chapter 9 before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e600 kcmil stranded copper conductor with 61 strands for improved pull flexibility\u003c\/li\u003e\n  \u003cli\u003eAmpacity ratings: 350 amps at 60 degrees C, 420 amps at 75 degrees C, 475 amps at 90 degrees C\u003c\/li\u003e\n  \u003cli\u003ePVC insulation with nylon jacket rated THHN, 600 volt, 90 degrees C dry\u003c\/li\u003e\n  \u003cli\u003eBlack insulation color for phase identification in conduit wiring systems\u003c\/li\u003e\n  \u003cli\u003eCut-to-length ordering from a 2500-foot reel to reduce material waste on large jobs\u003c\/li\u003e\n  \u003cli\u003eOuter diameter of 1024 mil supports accurate conduit fill planning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard THHN-rated stranded copper building wire suitable for use in conduit systems on commercial, industrial, and large residential electrical installations per NEC requirements.\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 all applicable local codes. De-energize and lock out the circuit before making any connections. Wire in this size class requires appropriate wire-pulling lubricant and mechanical or hydraulic compression lugs rated for 600 kcmil copper conductors. Conduit fill must be verified per NEC Chapter 9 before pulling to avoid insulation damage.\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: 600 kcmil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStranding\u003c\/strong\u003e: 61 Strand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpacity\u003c\/strong\u003e: 350 amps (60 degrees C), 420 amps (75 degrees C), 475 amps (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\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\u003eWire Type\u003c\/strong\u003e: THHN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1024 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1987 pounds per 1000 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReel Length\u003c\/strong\u003e: 2500 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: thhn600mcmstrblkmr\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51268956553522,"sku":"THHN600MCMSTRBLKMR","price":28979.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908885.jpg?v=1780710974","url":"https:\/\/voomisupply.com\/products\/thhncu-generic-thhn600mcmstrblkmr-thhn-600-kcmil-black-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
