It features 37-strand construction for flexibility and is insulated with PVC thermoplastic with a nylon jacket, meeting the THHN standard for use in conduit and cable trays. Current capacity ranges from 260 amps at 60 degrees C to 350 amps at 90 degrees C depending on installation conditions. This wire is sold cut to length and is suited for commercial and industrial electrical distribution, panel feeds, and service entrance applications where large-gauge copper conductors are required.\u003c\/p\u003e\u003cp\u003eThis wire is appropriate for use in commercial, industrial, and large residential electrical installations where high-ampacity branch circuits, feeder runs, or service conductors are needed. The brown insulation color supports color-coded phase identification in multi-conductor conduit runs. Licensed electricians and electrical contractors typically install 350 kcmil wire for main feeder and distribution panel work. Cut-to-length purchasing reduces material waste on job-specific conduit runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e350 kcmil stranded copper conductor with 37-strand construction for flexibility in conduit pulls\u003c\/li\u003e\n\u003cli\u003eTHHN-rated insulation: PVC thermoplastic with nylon jacket\u003c\/li\u003e\n\u003cli\u003e600-volt rating suitable for standard building power distribution\u003c\/li\u003e\n\u003cli\u003e90 degrees C dry rating with ampacity up to 350 amps\u003c\/li\u003e\n\u003cli\u003eBrown insulation for phase identification in conduit wiring systems\u003c\/li\u003e\n\u003cli\u003eCut-to-length format reduces job-site material waste\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard THHN-type 350 kcmil building wire suitable for use in conduit, wireways, and cable trays in commercial and industrial electrical systems per NEC guidelines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of 350 kcmil feeder wire should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out all circuits before beginning termination work. Wire of this gauge typically requires mechanical lugs, hydraulic crimping tools, and conduit pulling equipment sized for large-diameter conductors. Verify that all termination hardware, conduit fill, and overcurrent protection are sized to match the conductor ampacity and installation conditions.\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: 350 kcmil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStranding\u003c\/strong\u003e: 37 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: Brown\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\u003eAmpacity\u003c\/strong\u003e: 260 amps at 60 degrees C, 310 amps at 75 degrees C, 350 amps at 90 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 797 mil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1174 pounds per thousand feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: THHN\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: thhn350mcmstrbrnmr\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51268917395762,"sku":"THHN350MCMSTRBRNMR","price":16053.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908811.jpg?v=1780709642","url":"https:\/\/voomisupply.com\/products\/thhn-350-kcmil-stranded-copper-wire-brown-600v-cut-length","provider":"Voomi Supply","version":"1.0","type":"link"}
