Southwire 22966658 Thhn 12 Awg Stranded Wire 500 Ft Red

Product Description

The SOUTHWIRE/COLEMAN CABLE 22966658 is a 500-foot coil of 12 AWG stranded THHN building wire rated for 600 volts and 90 degrees C dry or damp locations. The conductor is soft-drawn copper with a nylon jacket over a PVC thermoplastic insulation, which gives it the slip needed to pull through conduit on longer runs. At 25.6 pounds per coil, it is a standard pull box or spool quantity used across residential and light commercial electrical installations. Licensed electricians reach for this wire on branch circuit rough-in, panel feeds, and conduit fill applications where a color-coded red conductor is required by code or job spec.

This wire is suited for residential and light commercial branch circuit wiring pulled through EMT, rigid metal, or PVC conduit. Red is commonly used as a secondary hot leg in 240-volt circuits, three-way switch legs, and multi-wire branch circuits. The 12 AWG stranded construction provides flexibility compared to solid wire, making it easier to terminate in tight junction boxes and panels. Electricians installing sub-panels, HVAC equipment circuits, and general 20-amp branch circuits will find this gauge and color appropriate for a wide range of NEC-compliant applications.

Key Features

• Type THHN insulation rated for 600 volts and 90 degrees C in dry or damp environments
• Stranded copper conductor for improved flexibility and easier termination compared to solid wire
• Nylon outer jacket reduces friction during conduit pulls, minimizing installation effort on long runs
• Red color coding supports code-compliant identification of secondary hot legs and switch legs
• 500-foot coil length suits full-room rough-ins and multi-circuit panel feeds without mid-run splices

Compatibility

Designed for use in conduit systems including EMT, rigid metal conduit, and Schedule 40 or Schedule 80 PVC conduit as permitted under NFPA 70 (NEC) for branch circuit and feeder wiring in residential and light commercial applications.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the circuit or panel before pulling, landing, or terminating conductors. Use a wire-pulling lubricant compatible with THHN insulation on longer conduit runs to prevent jacket damage. Do not exceed the ampacity or conduit-fill limits specified in NEC Tables 310 and Chapter 9 for the installed conditions.
