It features 15-mil thermoplastic insulation and a 4-mil nylon jacket. The insulation is rated for 90 degrees C in wet and dry conditions and 75 degrees C in oily environments, making it suitable for demanding commercial and residential electrical installations. This cable incorporates Simpull technology, which reduces pulling force and speeds up conduit runs. It ships on a 350-foot reel in a black, white, and green conductor configuration. Licensed electricians are the primary installers of this product.\u003c\/p\u003e\u003cp\u003eThis cable is used in feeders, branch circuits, conduits, raceways, and cable trays in both residential and commercial applications. The three-conductor configuration with a green ground wire suits standard branch circuit wiring in conduit systems. The 350-foot reel length is practical for larger rough-in jobs where longer continuous runs are needed without mid-run splices. The Simpull coating reduces friction during installation, which is especially helpful on longer pulls through conduit bends.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12\/3 AWG stranded copper construction for flexibility and conductivity\u003c\/li\u003e\n\u003cli\u003e600-volt rating suitable for standard branch circuit and feeder applications\u003c\/li\u003e\n\u003cli\u003e20-amp current rating for typical 12 AWG circuit loads\u003c\/li\u003e\n\u003cli\u003e15-mil thermoplastic insulation rated heat, moisture, oil, and sunlight resistant\u003c\/li\u003e\n\u003cli\u003e4-mil nylon jacket adds mechanical protection and pull-through durability\u003c\/li\u003e\n\u003cli\u003eSimpull technology reduces pulling force in conduit runs\u003c\/li\u003e\n\u003cli\u003e350-foot reel in black, white, and green for easy conductor identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in conduits, raceways, and cable trays in feeder and branch circuit applications per NEC requirements for THHN-rated conductors.\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 all applicable local codes. De-energize and lock out the circuit before making any connections. Use appropriate conduit fill calculations to ensure compliance with NEC conduit fill limits.
