Southwire 22972401 Thhn Thwn 12 Awg 20 Amp 500 Ft Wire

Product Description

The SOUTHWIRE 22972401 is a THHN/THWN dual-rated building wire designed for branch circuit and feeder wiring in residential, commercial, and industrial installations. This 12 AWG stranded copper conductor carries a 20-amp rating at 600 volts and runs 500 feet per spool. The 19-strand configuration provides added flexibility compared to solid wire, making it easier to pull through conduit on longer runs. Thermoplastic insulation and a nylon jacket deliver durability in demanding environments. Gray jacket color identifies the conductor for use in multi-wire circuits per standard color-coding practice.

This wire is rated for use in conduit, raceways, and approved enclosures in both dry and wet locations. The THWN rating extends suitability to wet or damp areas including outdoor conduit runs, mechanical rooms, and locations subject to moisture exposure. The THHN rating covers dry and damp locations where heat resistance up to 194 degrees F is required. It is a standard choice for licensed electricians running circuits to outlets, lighting panels, motors, and general-purpose loads in new construction and renovation work.

Key Features

• 20-amp, 600-volt rating suitable for standard 20-amp branch circuits
• Maximum operating temperature of 194 degrees F
• Nylon jacket resists abrasion, gasoline, heat, moisture, and oil
• 500-foot spool reduces splices on long conduit runs
• RoHS compliant; meets UL 83, UL 1063 (MTW), CSA, and Federal Specification A-A-59544

Compatibility

Designed for use in conduit, raceways, and other approved wiring enclosures where THHN or THWN-rated wire is specified for 12 AWG branch circuit or feeder applications at up to 600 volts.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit at the panel before pulling or terminating wire. Wire must be installed in conduit or approved raceways — direct burial is not a rated application for this product type. Verify conductor ampacity derating requirements when multiple current-carrying conductors are bundled in a single conduit.
