It carries a 600-volt rating and a 90 degrees C dry \/ 75 degrees C wet temperature rating, making it suitable for branch circuit wiring in conduit across a wide range of commercial and residential applications. The 19-strand copper conductor provides flexibility during pull-through compared to solid wire. PVC insulation with a nylon jacket meets the THHN designation. Licensed electricians install this wire as part of standard branch circuit and feeder runs.\u003c\/p\u003e\n\u003cp\u003eThis wire is used in residential and commercial electrical installations where THHN-rated conductors are required in conduit or cable trays. The gray insulation color is commonly used for neutral conductors in multi-wire branch circuits or for phase identification in larger multi-phase systems, depending on the installation's wiring scheme and local code requirements. The 500-foot spool length suits full-job pulls or stocking purposes for electrical contractors and maintenance electricians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12 AWG stranded copper conductor with 19-strand configuration for pull flexibility\u003c\/li\u003e\n  \u003cli\u003eRated 600 volts for standard branch circuit and feeder wiring\u003c\/li\u003e\n  \u003cli\u003eTemperature rated 90 degrees C dry and 75 degrees C wet\u003c\/li\u003e\n  \u003cli\u003e20-amp current capacity at 60, 75, and 90 degrees C\u003c\/li\u003e\n  \u003cli\u003ePVC insulation with THHN designation\u003c\/li\u003e\n  \u003cli\u003eGray insulation for phase or neutral identification per installation wiring scheme\u003c\/li\u003e\n  \u003cli\u003e500-foot spool for high-volume pulls or contractor stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in conduit or cable tray installations requiring THHN-rated 12 AWG building wire in residential, commercial, and light industrial electrical systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes.
