Thhn 10 Awg Stranded Gray Copper Wire 500 Ft Spool

Product Description

The THHN-GENERIC thhn10strgry500r is a 10 AWG stranded copper THHN wire supplied on a 500-foot spool in gray insulation. Built with 19-strand copper construction, this wire is rated for 600 volts and 30 amps, with a 90 degrees C dry temperature rating. The PVC insulation is jacketed in nylon, which provides abrasion resistance and makes it suitable for pulling through conduit. Licensed electricians install this wire in branch circuit and feeder wiring applications across residential, commercial, and light industrial settings.

This wire is used in conduit runs for panel feeders, branch circuits, and general-purpose wiring where THHN-rated conductors are required. The gray insulation color is commonly used for neutral or phase identification depending on local color-coding practices. The 500-foot spool length suits mid-sized jobs where full 1,000-foot reels would be wasteful. The 0.161-inch outer diameter allows smooth pulls through standard conduit fittings and bends.

Key Features

• 10 AWG stranded copper conductor with 19-strand configuration for flexibility
• 600-volt rating suitable for standard branch circuit and feeder wiring
• 30-amp current capacity for typical 10 AWG circuit loads
• PVC insulation with nylon jacket rated at 90 degrees C dry for conduit pulls
• Gray insulation color for conductor identification per local wiring practices
• 500-foot spool length reduces waste on mid-sized electrical installations

Compatibility

Designed as an OEM-style replacement and general-use THHN conductor suitable for installation in EMT, rigid metal conduit, PVC conduit, and other NEC-approved raceway systems where THHN wire is specified.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit and verify zero voltage with a meter before terminating conductors. Use listed wire-pulling lubricant to reduce friction on long conduit runs and avoid exceeding the conductor's minimum bend radius. Terminate at rated connectors and lugs sized for 10 AWG copper conductors.
