Rated for 600 volts and up to 90 degrees C in dry installations, this wire carries up to 350 amps at 90 degrees C, making it suitable for high-ampacity feeder and branch circuit runs. The 37-strand construction improves flexibility during pull-through in conduit. This wire is sold cut to length and is typically installed by licensed electricians on commercial and industrial projects requiring large-gauge conductors.\u003c\/p\u003e\u003cp\u003eThis wire is used in feeder applications, service entrance runs, and large branch circuits in commercial, industrial, and high-demand residential installations. The THHN rating makes it appropriate for conduit installations in dry environments. The red insulation color supports standard phase identification and color-coding practices used in electrical distribution panels and switchgear. Electricians working on 480-volt and 208-volt three-phase systems commonly specify this conductor size for motor feeders and sub-panel feeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e350 kcmil copper conductor with 37-strand construction for improved pull flexibility\u003c\/li\u003e\n\u003cli\u003e600-volt rating suitable for commercial and industrial power distribution\u003c\/li\u003e\n\u003cli\u003eTemperature ratings of 260 amps at 60 degrees C, 310 amps at 75 degrees C, and 350 amps at 90 degrees C\u003c\/li\u003e\n\u003cli\u003ePVC thermoplastic insulation with nylon jacket for abrasion and moisture resistance\u003c\/li\u003e\n\u003cli\u003eRed insulation color for phase identification in multi-conductor installations\u003c\/li\u003e\n\u003cli\u003eCut-to-length availability reduces waste on large feeder runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in conduit systems requiring THHN-rated 350 kcmil copper building wire rated at 600 volts in dry locations, consistent with NEC ampacity and installation requirements for large-gauge feeder conductors.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of 350 kcmil THHN wire should be performed by a licensed electrician in accordance with NEC Article 310 and applicable local codes. De-energize and lock out all circuits before making connections. Use appropriately rated wire-pulling lubricant and conduit fill calculations to avoid exceeding conduit capacity. Terminations require lugs or connectors rated for the conductor size and material.\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\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\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: Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.797 inches\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: thhn350mcmstrredmr\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51267874128178,"sku":"THHN350MCMSTRREDMR","price":16053.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908879.jpg?v=1780692958","url":"https:\/\/voomisupply.com\/products\/thhn-350-kcmil-stranded-copper-wire-350-amp-red","provider":"Voomi Supply","version":"1.0","type":"link"}
