Southwire 11594901 Thhn Thwn 12 Awg 20A 500ft Solid Wire

Product Description

The SOUTHWIRE 11594901 is a 12 AWG solid copper THHN/THWN building wire rated for 20 amps at 600 volts. The single-conductor wire features brown thermoplastic insulation with a nylon jacket, making it suitable for use in conduit in dry, damp, and wet locations. It ships as a 500-foot spool and weighs 12.5 pounds. Electricians use this wire for branch circuit wiring in residential and light commercial construction where a 20-amp circuit is required. The nylon jacket provides resistance to abrasion, gasoline, heat, moisture, and oil.

This wire is used in branch circuit and feeder applications in residential and commercial buildings. Common install scenarios include general-purpose 20-amp circuits for receptacles, appliances, and lighting routed through conduit. The brown jacket color is standard for identifying hot conductors in multi-wire branch circuits and assists with color-coded circuit organization during rough-in and finish electrical work.

Key Features

• Brown nylon-jacketed thermoplastic insulation for use in conduit in wet or dry locations
• Dual-rated THHN and THWN for versatility across conduit wiring applications
• Resistant to abrasion, gasoline, heat, moisture, and oil
• Maximum operating temperature of 194 degrees F
• 500-foot spool per package — full roll for branch circuit rough-in work

Compatibility

Designed for use in conduit as a branch circuit conductor in residential and light commercial electrical systems where THHN or THWN-rated 12 AWG solid wire is specified.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Power down and lock out the circuit before connecting or terminating any conductors. Solid 12 AWG wire is intended for use in conduit and is not rated for free-air applications where stranded wire is typically specified. Pull wire carefully to avoid nicking the insulation during conduit installation.
