It carries a 600-volt rating and supports current capacity of 70 amps at 60 degrees C, 85 amps at 75 degrees C, and 100 amps at 90 degrees C. The 19-strand copper conductor provides flexibility during pull-through in conduit runs. The nylon jacket adds abrasion resistance and helps the wire pull cleanly through tight conduit bends. This wire is a standard choice for branch circuit wiring in residential, commercial, and light industrial electrical installations.\u003c\/p\u003e\u003cp\u003eTHHN wire of this gauge is used in conduit installations for branch circuits, feeder runs, and service entrance applications where a 600-volt, 90 degrees C dry-rated conductor is required. The blue insulation color is commonly used by electricians to designate specific phase or circuit identification in multi-wire systems. This product is sold cut to length, making it practical for jobs that require a specific footage rather than a full reel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 AWG copper conductor with 19-strand construction for flexibility in conduit\u003c\/li\u003e\n\u003cli\u003eTHHN type rated at 600 volts and 90 degrees C dry service\u003c\/li\u003e\n\u003cli\u003eCurrent ratings of 70A at 60 degrees C, 85A at 75 degrees C, and 100A at 90 degrees C\u003c\/li\u003e\n\u003cli\u003ePVC insulation with nylon outer jacket for abrasion resistance and easier pulling\u003c\/li\u003e\n\u003cli\u003eBlue insulation for circuit identification in multi-wire conduit runs\u003c\/li\u003e\n\u003cli\u003eCut-to-length availability reduces waste on specific footage requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in conduit systems requiring THHN-rated 4 AWG copper conductors at 600 volts, suitable for dry locations in residential, commercial, and light industrial branch circuit and feeder wiring applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTHHN wire must be installed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit and verify with a meter before making connections. Use appropriately rated conduit, connectors, and terminations for the conductor gauge and ampacity. Do not exceed the temperature or voltage ratings stamped on the insulation.\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 at 60 degrees C, 85 amps at 75 degrees C, 100 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: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 318 mil\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: THHNCU-GENERIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: thhn4strblumr\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51268856742194,"sku":"THHN4STRBLUMR","price":2354.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908501.jpg?v=1780707757","url":"https:\/\/voomisupply.com\/products\/thhncu-generic-thhn4strblumr-4-awg-thhn-copper-wire-blue","provider":"Voomi Supply","version":"1.0","type":"link"}
