Thhn 12 Awg Stranded Copper Wire Yellow 500 Foot Spool

Product Description

The THHNCU-GENERIC thhn12stryel500r is a 12 AWG stranded copper THHN building wire rated for use in general-purpose electrical wiring applications. This wire features a PVC insulation layer over a 19-strand copper conductor, with an outer nylon jacket that provides added abrasion and chemical resistance. It carries a 600-volt rating and a 90 degrees C temperature rating in dry environments and 75 degrees C in wet environments. The yellow insulation color allows for quick circuit identification during installation and inspection. Licensed electricians install this wire in residential, commercial, and light industrial settings.

This 500-foot spool of 12 AWG THHN wire is suited for branch circuit wiring in conduit, raceways, and cable trays. Common applications include general lighting circuits, receptacle circuits, and panel feeders where a 20-amp conductor is required. The stranded construction makes it easier to pull through conduit compared to solid wire, and it handles well in tight bend radius situations. The yellow jacket provides consistent color coding for neutral, switched-leg, or other circuit identification per local electrical code conventions.

Key Features

• 12 AWG copper conductor with 19-strand construction for flexibility during conduit pulls
• Dual-layer jacket: PVC insulation over nylon outer jacket for abrasion and chemical resistance
• 600-volt rated for standard branch circuit and feeder applications
• 90 degrees C dry and 75 degrees C wet temperature ratings for broad environmental use
• Yellow insulation for easy circuit identification in panels and junction boxes
• 500-foot spool provides enough length for most single-circuit rough-in runs

Compatibility

Designed for use in conduit, raceways, and cable trays in accordance with NEC requirements for THHN-type building wire. Suitable for 20-amp branch circuit applications where 12 AWG copper conductors are specified.

Installation Notes

Installation should be performed by a licensed electrician in compliance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit and verify absence of voltage before making any terminations. Use appropriately rated wire connectors, terminals, and conduit fittings sized for 12 AWG conductors. Do not exceed the conductor ampacity or temperature ratings listed on the spool label.
