Southwire 22977357 Thhn 10 Awg 500 Ft Stranded Copper Wire

Product Description

The SOUTHWIRE COLEMAN CABLE 22977357 is a 500-foot spool of 10 AWG stranded copper THHN building wire in green insulation. THHN (Thermoplastic High Heat-resistant Nylon-coated) wire carries a nylon jacket over a thermoplastic insulation layer, rated for 90 degrees C dry and 75 degrees C wet environments at up to 600 volts. The stranded copper conductor provides flexibility during pulls through conduit, making it a standard choice for branch circuit wiring, panel feeds, equipment grounding, and general electrical distribution. Licensed electricians install this wire in commercial and residential applications in compliance with NEC requirements.

This wire is suited for use in conduit runs in commercial buildings, industrial facilities, and residential construction. The green insulation color is the NEC-standard designation for equipment grounding conductors, making this spool a go-to for grounding applications in panel boards, junction boxes, and equipment connections. It handles typical branch circuit and feeder work where a flexible stranded conductor is preferred over solid wire for ease of termination and routing through tight conduit bends.

Key Features

• 10 AWG stranded copper conductor for flexibility during conduit installation
• Type THHN with nylon jacket rated for 600 volts
• 90 degrees C temperature rating for dry environments
• Green insulation — NEC-standard color for equipment grounding conductors
• 500-foot spool length suitable for larger runs without mid-run splices

Compatibility

Designed for use in conduit or raceways as required by NEC Article 310; compatible with standard 10 AWG termination lugs, breakers, and connectors rated for stranded copper conductors.

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 and lock out the circuit or panel before making any terminations. Use appropriately sized conduit and pulling lubricant for longer runs to avoid insulation damage. Confirm that all termination points — breakers, lugs, and connectors — are rated for stranded copper at 10 AWG.
