Southwire 20493301 Thhn Thwn 6 Awg 55A Building Wire

Product Description

The SOUTHWIRE 20493301 is a 6 AWG stranded copper THHN/THWN building wire rated for 55 amps at 600 volts. It features a thermoplastic insulation layer with a nylon jacket, making it suitable for use in conduit in both wet and dry locations. The conductor is built with 19 strands for flexibility during pulling and routing through conduit systems. This wire is sold in 1-foot increments with a 250-foot minimum cut length from a 500-foot coil. Licensed electricians install this wire in branch circuit and feeder applications across residential, commercial, and light industrial projects.

This wire is used in conduit runs for branch circuits, panel feeds, and general-purpose wiring in buildings. Its dual THHN/THWN rating makes it suitable for both dry and wet conduit environments. The black jacket color aids in circuit identification during installation. Typical applications include service entrance feeders, motor branch circuits, and general building wiring where a 6 AWG conductor is specified. The 19-strand configuration makes it easier to pull through longer or more complex conduit runs compared to solid conductor wire.

Installation Notes

Installation must 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 or panel before making any connections. Wire must be pulled through listed conduit; do not use as open wiring or staple directly to framing. Verify conductor ampacity and conduit fill calculations prior to installation per NEC Chapter 9 tables.
