Southwire 20496601 Thhn Thwn 6 Awg 55A Building Wire

Product Description

The SOUTHWIRE 20496601 is a single-conductor THHN/THWN building wire rated at 6 AWG and 55 amps, built for use in commercial and residential electrical installations. The stranded copper core consists of 19 strands, delivering flexibility for pulling through conduit runs. Thermoplastic insulation with a nylon jacket provides a 600-volt rating and a maximum operating temperature of 194 degrees F. The blue jacket color allows for straightforward circuit identification during rough-in and finish wiring work. Licensed electricians install this wire in branch circuit and feeder applications following NEC requirements.

This wire is suited for use in dry, damp, or wet locations where THHN or THWN conductor ratings are required. The 19-strand stranded core makes it manageable in tight conduit bends and junction boxes compared to solid wire of the same gauge. Typical applications include feeder runs to subpanels, branch circuits for HVAC equipment, and general-purpose building wiring in both light commercial and residential construction. The nylon jacket adds resistance to abrasion, oil, gasoline, and moisture, making it appropriate for industrial environments as well. This product is sold in 1-foot increments with a 250-foot minimum cut length from a 500-foot coil.

Key Features

Compatibility

Designed for use in conduit-fed branch circuit and feeder wiring systems where THHN or THWN single-conductor wire at 6 AWG is specified per NEC or local electrical code requirements.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out all circuits before connecting or splicing conductors. When pulling through conduit, use a listed wire-pulling lubricant to avoid jacket damage. Verify conduit fill calculations for the specific conduit type and size before installation.
