Southwire 22964158 Thhn Wire 12 Awg Stranded Black 500 Ft

Product Description

The SOUTHWIRE 22964158 is a 500-foot roll of 12 AWG stranded THHN building wire in black. It is rated for 600 volts and up to 90 degrees C, making it suitable for power distribution, lighting circuits, and control wiring in commercial and residential construction. The conductor is stranded copper, insulated with flame-retardant PVC and finished with a nylon jacket. That jacket adds resistance to oil, gasoline, chemicals, and abrasion, extending service life in demanding conduit runs. Electricians reach for this wire on new construction, tenant improvement, and panel-feed projects where code-compliant general-purpose wiring is required.

This wire is designed for installation inside conduit and raceways, as required by NEC for most enclosed wiring applications. The 12 AWG gauge is among the most common sizes used for 20-amp branch circuits in residential and light commercial work, including outlets, lighting, and small appliance circuits. The 500-foot roll length reduces the number of splices on larger jobs and suits service vehicles stocking a single pull for full-floor or full-unit wiring runs.

Key Features

• 12 AWG stranded copper conductor for flexibility during pull-through in conduit
• 600-volt rating covers standard branch circuit and feeder applications
• 90 degrees C temperature rating for use in higher-ambient environments
• Flame-retardant PVC insulation with nylon jacket resists oil, gasoline, chemicals, and abrasion
• UL listed for compliance with NEC installation requirements
• 500-foot roll reduces splices on large wiring runs

Compatibility

Designed for use in conduit and raceway systems as a general-purpose THHN building wire for power, lighting, and control wiring applications in residential and commercial construction.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify absence of voltage at the panel before pulling or terminating any conductors. THHN wire must be installed inside an approved conduit or raceway — it is not rated for direct burial or open-air exposed runs without additional protection. Use a wire-pulling lubricant rated compatible with PVC insulation to reduce friction on long conduit runs.
