Southwire 20495801 Thhn Thwn 6 Awg 55A Building Wire

Product Description

The SOUTHWIRE 20495801 is a 6 AWG stranded copper THHN/THWN building wire rated for 55 amps and 600 volts. It features a thermoplastic insulation layer with a nylon jacket in red, making it suitable for branch circuit wiring in commercial and residential construction. The 19-strand copper core provides flexibility during pull-through conduit installations. Licensed electricians and electrical contractors install this wire in accordance with NEC requirements. The dual THHN/THWN rating means it is listed for both dry and wet locations, adding versatility to a single conductor product used across a wide range of applications.

This wire is sold in 1-foot increments with a 250-foot minimum cut length from a 500-foot total coil. It is used in conduit runs for panel feeds, sub-panel wiring, motor circuits, and general branch circuit applications in residential, commercial, and light industrial settings. The red jacket color aids in phase identification during installation. Electricians pulling wire through conduit on new construction or retrofit projects will find the stranded construction easier to handle than solid core alternatives of the same gauge.
