The conductor is built from 19-strand copper with a PVC insulation layer and an outer nylon jacket. This combination gives the wire its THHN designation and makes it suitable for pulling through conduit in commercial and residential electrical work. Current capacity ranges from 70 amps at 60 degrees C to 100 amps at 90 degrees C, depending on the installation temperature rating. The reel contains 500 feet of black-insulated wire. Licensed electricians are the primary installers for this product in branch circuit, feeder, and service-entrance wiring applications.\u003c\/p\u003e\u003cp\u003eThis wire is used in conduit runs for branch circuits, feeder conductors, and service panels in both residential and commercial construction. The 4 AWG size is common in sub-panel feeds, large appliance circuits, and equipment branch circuits where higher ampacity is required. The 500-foot reel format is suited for larger jobs or multi-run conduit work. The black insulation color is standard for ungrounded phase conductors in most installations and aligns with NEC color convention for line-side conductors.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 AWG copper conductor with 19-strand configuration for flexibility during conduit pulls\u003c\/li\u003e\n\u003cli\u003eDual-layer insulation: PVC over copper, nylon jacket rated for THHN service\u003c\/li\u003e\n\u003cli\u003e600-volt rating suitable for standard building wiring applications\u003c\/li\u003e\n\u003cli\u003e90 degrees C dry temperature rating for maximum ampacity of 100 amps\u003c\/li\u003e\n\u003cli\u003eBlack PVC insulation for phase conductor identification\u003c\/li\u003e\n\u003cli\u003e500-foot reel length reduces splicing on longer conduit runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in conduit systems as a THHN-rated building wire for residential and commercial electrical installations where 4 AWG copper conductors are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Power must be de-energized and locked out at the panel before terminating conductors. THHN wire is intended for use inside conduit and is not rated for direct burial or wet locations without additional protection. Use appropriately rated lugs, breakers, and termination hardware sized for 4 AWG conductors.\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: 4 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStranding\u003c\/strong\u003e: 19 Strand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 70 amps (60 degrees C), 85 amps (75 degrees C), 100 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\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: 318 mil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReel Length\u003c\/strong\u003e: 500 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 152 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: THHN-GENERIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: thhn4strblk500r\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51268363190578,"sku":"THHN4STRBLK500R","price":2464.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908602.jpg?v=1780703273","url":"https:\/\/voomisupply.com\/products\/thhn-4-awg-stranded-copper-wire-black-500-foot-reel","provider":"Voomi Supply","version":"1.0","type":"link"}
