Southwire 22965851 Thhn Thwn 12 Awg 20A 50 Ft Stranded Wire

Product Description

The SOUTHWIRE 22965851 is a 50-foot spool of 12 AWG THHN/THWN stranded copper building wire rated for 20 amps at 600 volts. It features a white thermoplastic insulation with a nylon jacket, making it suitable for dry, damp, and wet location wiring in conduit. The conductor is made up of 19 strands, providing flexibility during installation compared to solid wire. Licensed electricians install this wire in residential and light commercial applications where NEC-compliant branch circuit wiring is required. The dual THHN/THWN rating broadens its approved use across a wide range of conduit runs.

This wire is used in residential and commercial construction for branch circuit wiring, panel feeders, and conduit fill applications. It is well suited for indoor conduit runs in walls, ceilings, and electrical panels, as well as outdoor conduit applications where moisture resistance is needed. The white jacket color follows standard NEC color-coding conventions for neutral conductors in single-phase systems, helping electricians maintain consistent identification across installations.

Key Features

• 12 AWG stranded copper conductor with 19 strands for improved flex and pull-through
• Dual-rated THHN/THWN for dry, damp, and wet location use in conduit
• 600-volt rating suitable for standard branch circuit applications
• Maximum operating temperature of 194 degrees F
• Nylon jacket provides resistance to abrasion, heat, moisture, oil, and gasoline
• White jacket color for neutral conductor identification per NEC conventions

Compatibility

Designed for use in conduit-based branch circuit wiring in residential and light commercial electrical systems where THHN or THWN-rated conductors are specified.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify with a meter before making any connections. Pull wire through conduit using appropriate lubricant to avoid jacket damage; do not exceed the manufacturer-rated bend radius. Confirm conduit fill calculations comply with NEC Chapter 9 tables before pulling multiple conductors.
