Southwire 11588101 Thhn Thwn 12 Awg 20 Amp 500 Ft Solid Wire

Product Description

The SOUTHWIRE 11588101 is a 12 AWG solid copper THHN/THWN building wire rated for 20 amps at 600 volts, supplied in a 500-foot spool. The conductor is a single solid copper strand with thermoplastic insulation and a nylon jacket in white. Rated for a maximum operating temperature of 194 degrees F, this wire is built for general-purpose branch circuit wiring in residential and light commercial applications. Electricians install it in conduit runs where both dry and wet location ratings are required. The dual THHN/THWN listing makes it a versatile choice for a wide range of conduit-fed wiring installations.

This wire is used in residential, commercial, and industrial branch circuit wiring routed through conduit. It is suited for panel feeders, outlet circuits, lighting circuits, and equipment connections where 12 AWG conductors at 20-amp capacity are specified. The solid core construction is standard for shorter branch circuit runs in conduit. The white jacket color supports neutral conductor identification per common wiring practice. Electricians working on NEC-compliant installations will find this wire meets the conductor requirements for standard 20-amp circuits.

Compatibility

Designed as an OEM-style replacement and standard-stock conductor for conduit-fed branch circuit wiring in residential and light commercial electrical systems requiring 12 AWG THHN/THWN solid copper wire.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize the circuit and verify absence of voltage before pulling, terminating, or splicing conductors. This wire is rated for installation inside conduit only and must not be used as open wiring or direct burial without additional protection. Confirm conduit fill calculations comply with NEC Chapter 9 tables before pulling multiple conductors.
