THHN-rated wire is a standard choice for branch circuit and feeder wiring in conduit runs across residential, commercial, and industrial applications. The 250 kcmil conductor size handles high-ampacity loads and is commonly pulled by licensed electricians on service entrance feeders, panel feeds, and heavy-equipment circuits. The stranded construction improves flexibility during pull-through in conduit compared to solid conductors of the same gauge.\u003c\/p\u003e\u003cp\u003eThis wire is suited for use in dry and damp locations inside conduit or raceway systems. The gray insulation color is used in multi-conductor installations where color coding helps identify conductors during termination and inspection. Electricians working on large commercial panels, industrial machinery feeds, or sub-panel installations will find the cut-to-length format reduces material waste on job-specific runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e250 kcmil conductor size rated for high-ampacity feeder and branch circuit applications\u003c\/li\u003e\n\u003cli\u003eStranded copper construction for improved flexibility during conduit installation\u003c\/li\u003e\n\u003cli\u003eGray THHN insulation for conductor identification in multi-wire assemblies\u003c\/li\u003e\n\u003cli\u003eCut-to-length format minimizes waste on custom-length pulls\u003c\/li\u003e\n\u003cli\u003eTHHN insulation rating suitable for dry and damp locations in conduit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard THHN-rated stranded copper building wire for use in conduit or raceway systems where 250 kcmil conductors are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits and verify zero voltage before terminating or connecting conductors. Use appropriate conduit fill calculations per NEC Chapter 9 to confirm raceway sizing. Do not exceed the ampacity ratings listed in NEC Table 310 for the specific installation conditions and ambient temperature.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Size\u003c\/strong\u003e: 250 kcmil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Construction\u003c\/strong\u003e: Stranded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Type\u003c\/strong\u003e: THHN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Color\u003c\/strong\u003e: Gray\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: thhn250mcmstrgrymr\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51268067492146,"sku":"THHN250MCMSTRGRYMR","price":11583.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908979.jpg?v=1780698243","url":"https:\/\/voomisupply.com\/products\/thhncu-generic-thhn250mcmstrgrymr-thhn-250-mcm-gray-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
