Southwire 22870001 Thhn Thwn 12 Awg 20 Amp 500 Ft Solid Wire

Product Description

The SOUTHWIRE 22870001 is a solid-core THHN/THWN building wire rated at 12 AWG and 20 amps, designed for general-purpose electrical wiring in residential and light commercial construction. This 500-foot spool features a solid copper conductor with thermoplastic insulation and a gray nylon jacket rated for up to 600 volts. The gray color coding helps electricians maintain conductor identification in multi-wire installations. It is installed by licensed electricians and meets a broad set of industry standards including UL 83, UL 1063 (MTW), CSA, and RoHS compliance, making it suitable for use in conduit runs in both dry and wet locations.

This wire is suited for branch circuit wiring in residential homes, commercial buildings, and light industrial panels. It is commonly pulled through EMT, rigid conduit, or PVC conduit for general-purpose 20-amp circuits including outlets, lighting, and appliance circuits. The THWN dual rating allows use in wet or damp locations. The solid conductor construction is standard for shorter branch circuit runs and is widely accepted by local codes for in-wall and in-conduit residential applications.

Key Features

• 12 AWG solid copper conductor rated for 20 amps at 600 volts
• Dual THHN/THWN rating for use in dry and wet conduit installations
• Gray nylon jacket aids conductor color identification on the job
• Thermoplastic insulation rated to 194 degrees F maximum operating temperature
• Resistant to abrasion, gasoline, heat, moisture, and oil
• Meets UL 83, UL 1063 (MTW), CSA, Federal Specification A-A-59544, RoHS, and Green Specification standards

Compatibility

Designed for use in conduit-based branch circuit wiring applications where THHN or THWN-rated conductors are required by code. Compatible with standard 12 AWG wire terminations, lugs, and connectors rated for solid copper conductors.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify zero voltage with a meter before terminating at any panel, junction box, or device. Solid conductor wire requires proper seating at screw terminals and should not be used where stranded wire is explicitly required by the device manufacturer. Do not exceed the wire's 600-volt or 20-amp ratings.
