Southwire 20494101 Thhn Thwn 6 Awg 55A Building Wire

Product Description

The SOUTHWIRE 20494101 is a THHN/THWN dual-rated building wire designed for use in commercial and residential electrical installations. This 6 AWG stranded copper wire features a 19-strand core, a thermoplastic insulation layer, and a white nylon jacket. It carries a 55-amp rating at 600 volts and is suited for branch circuit wiring, feeder runs, and general-purpose electrical distribution work. Licensed electricians install this wire in conduit systems, panel feeders, and service entrance applications. The thermoplastic insulation and nylon outer jacket provide resistance to abrasion, heat, moisture, oil, and gasoline exposure, making it a reliable choice for demanding environments.

This wire is intended for use in conduit or raceway installations in both residential and commercial construction. Typical applications include branch circuit wiring in electrical panels, motor feeder runs, and general building wiring where THHN or THWN dual-rated conductors are required by code. The white jacket color aids in phase and circuit identification during installation. This product is sold in 1-foot increments with a 250-foot minimum cut length, and comes on a 500-foot total coil. Electricians and electrical contractors working on new construction or retrofit projects will find this wire suitable for a wide range of load-bearing circuit applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit and verify zero voltage at the panel before pulling or terminating this wire. This wire is rated for use in conduit or approved raceway systems and should not be used as open wiring or in applications outside its listed ratings. Use appropriate wire-pulling lubricant and conduit fill calculations to ensure a code-compliant installation.
