Southwire 11589901 Thhn Thwn 12 Awg 20A 500ft Solid Copper Wire

Product Description

The SOUTHWIRE 11589901 is a 12 AWG solid copper building wire rated for THHN and THWN applications, carrying up to 20 amps at 600 volts. The conductor is insulated with thermoplastic and jacketed with nylon, producing a durable construction that resists abrasion, heat, moisture, oil, and gasoline exposure. The red jacket aids circuit identification in panel and conduit work. This 500-foot spool is suited for residential and light commercial branch circuit wiring installed by licensed electricians working to NEC standards.

This wire is used in dry and wet locations where THHN or THWN-rated conductors are required. Typical applications include branch circuit runs in conduit for lighting, receptacle, and appliance circuits in residential, commercial, and industrial settings. The solid core construction is well suited for 12 AWG conduit pulls and terminations at breakers, receptacles, and junction points. The 500-foot spool length accommodates longer runs without splices.

Key Features

• Dual-rated THHN and THWN for use in both dry and wet conduit installations
• Solid copper conductor provides reliable conductivity and firm terminal connections
• Nylon outer jacket resists abrasion, gasoline, oil, and moisture
• Thermoplastic insulation rated to 194 degrees F maximum operating temperature
• Red jacket color supports circuit identification and NEC color-coding practices
• Meets UL 83, UL 1063 (MTW), CSA, RoHS, and Federal Specification A-A-59544 standards

Compatibility

Designed for use in conduit systems requiring THHN or THWN-rated 12 AWG branch circuit conductors in residential, commercial, and industrial electrical installations.

Installation Notes

Installation should 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 making any terminations. Solid 12 AWG conductors require proper torque at terminals per the device or breaker manufacturer specifications found on the equipment listing label. Pull wire through conduit using appropriate wire-pulling lubricant to avoid jacket damage.
