Southwire 11591501 Thhn Thwn 12 Awg 20A Solid Copper Wire

Product Description

The SOUTHWIRE 11591501 is a 12 AWG solid copper THHN/THWN building wire rated for 20 amps at 600 volts. The conductor is insulated with thermoplastic and jacketed with nylon, producing a wire that meets the dual THHN/THWN rating for both dry and wet location use. This spool ships in a 500-foot length and is color-coded green, making it the standard choice for equipment grounding conductors in branch circuit wiring. Licensed electricians install this wire in residential, commercial, and light industrial conduit runs.

This wire is used in conduit installations where NEC-compliant grounding conductors are required. The green jacket identifies it as an equipment grounding conductor per NEC Article 250. Typical applications include branch circuit grounding in panel feeders, motor circuits, and general-purpose outlet circuits in both new construction and retrofit work. The solid core construction is well suited for conduit pulls in shorter runs and for terminations at devices, panels, and junction boxes.

Key Features

• Dual-rated THHN/THWN insulation suitable for dry and wet locations
• 12 AWG solid copper conductor rated for 20 amps at 600 volts
• Nylon outer jacket provides resistance to abrasion, moisture, oil, and gasoline
• Maximum operating temperature of 194 degrees F
• Green jacket meets NEC equipment grounding conductor color identification requirements
• 500-foot spool length reduces mid-run splices on longer conduit pulls

Compatibility

Designed for use in conduit systems requiring NEC-compliant 12 AWG equipment grounding conductors in residential, commercial, and light industrial installations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize the circuit and verify absence of voltage at the panel before pulling or terminating this wire. This wire is intended for use inside conduit and is not rated for direct burial or free-air use outside a raceway. Solid conductors at this gauge require appropriate connectors or terminals rated for solid wire.
