It is sold cut to length, making it practical for commercial and residential electrical rough-in work where specific footage is needed. The 19-strand construction provides flexibility compared to solid conductors of the same gauge, easing pull-through in conduit runs. Current capacity is 85 amps at 60 degrees C, 100 amps at 75 degrees C, and 115 amps at 90 degrees C, depending on the applicable temperature rating of the terminations and conduit fill conditions. Licensed electricians and electrical contractors are the primary installers.\u003c\/p\u003e\u003cp\u003eThis wire is suited for branch circuit wiring, feeder runs, and panel connections in conduit installations in both residential and commercial construction. The blue insulation color is commonly used to designate specific circuits or phases per job-site wiring conventions. Cut-to-length availability reduces waste on jobs where standard spool footage exceeds the required run. The 3 AWG size is frequently used for 100-amp subpanel feeds, large appliance circuits, and similar higher-ampacity branch circuits where NEC Table 310 ampacity requirements must be met.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3 AWG copper conductor with 19-strand construction for flexibility in conduit\u003c\/li\u003e\n\u003cli\u003eTHHN type with PVC insulation and nylon jacket rated to 600 volts\u003c\/li\u003e\n\u003cli\u003e90 degrees C dry temperature rating with tiered ampacity up to 115 amps\u003c\/li\u003e\n\u003cli\u003eBlue PVC insulation for circuit identification per job-site color coding\u003c\/li\u003e\n\u003cli\u003eSold cut to length to minimize material waste on specific run lengths\u003c\/li\u003e\n\u003cli\u003eOuter diameter of 346 mil for conduit fill calculation purposes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in conduit systems as a general-purpose THHN building wire suitable for branch circuit and feeder applications governed by NEC installation requirements.\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. Always de-energize and lock out the circuit before terminating or splicing wire. THHN wire must be installed inside approved conduit and is not rated for direct burial or wet locations without an additional wet-rated jacket. Verify that all termination points, breakers, and lugs are rated for the same temperature column used to determine ampacity to avoid derating violations.\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: 3 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStranding\u003c\/strong\u003e: 19-Strand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmpacity\u003c\/strong\u003e: 85 amps at 60 degrees C, 100 amps at 75 degrees C, 115 amps at 90 degrees C\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: 346 mil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 189 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: thhn3strblumr\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51268074701106,"sku":"THHN3STRBLUMR","price":2967.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908760.jpg?v=1780698399","url":"https:\/\/voomisupply.com\/products\/thhncu-generic-thhn3strblumr-thhn-3-awg-copper-wire-blue","provider":"Voomi Supply","version":"1.0","type":"link"}
