Thhn 14 Awg Stranded Copper Wire Gray 2500 Ft Reel

Product Description

The THHNCU-GENERIC thhn14strgry2500r is a 14 AWG stranded copper building wire rated for use in conduit and cable tray installations. The conductor is made up of 19 strands of copper for flexibility during pull-through, covered with a PVC thermoplastic insulation layer and a nylon jacket in gray color. It carries a 600-volt rating and a 90 degrees C temperature rating in dry conditions, making it suitable for branch circuit wiring in commercial and residential construction. Licensed electricians install this wire as part of conduit runs where a color-coded gray conductor is required for circuit identification.

This wire is used in residential, commercial, and light industrial electrical systems where THHN-rated conductors are required inside conduit or raceways. The 2500-foot reel length is suited for larger projects or supply stocking where minimizing reel changes during installation improves workflow efficiency. Gray insulation is commonly used in multi-wire branch circuits for neutral or traveler identification depending on local wiring conventions. The 15-amp current rating at standard temperature ratings aligns with standard 14 AWG branch circuit applications under NEC guidelines.

Key Features

• 14 AWG stranded copper conductor with 19-strand configuration for pull flexibility
• Gray PVC thermoplastic insulation with nylon jacket for abrasion resistance
• 600-volt rating suitable for standard branch circuit wiring
• 90 degrees C dry temperature rating for use in high-ambient environments
• 2500-foot reel minimizes splices and reel changes on large jobs
• 0.109-inch outer diameter for conduit fill calculations

Compatibility

Designed for use in conduit, raceways, and cable trays as a THHN-rated building wire per NEC Article 310 requirements for branch circuit and feeder wiring.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code and applicable local codes. De-energize and lock out the circuit before terminating conductors. THHN wire must be installed inside an approved conduit or raceway and is not rated for direct burial or exposed outdoor use without additional protection. Verify conduit fill percentages using the published outer diameter before pulling wire.
