Thhn 10 Awg Solid Copper Wire Blue 500 Foot Spool

Product Description

The THHNCU-GENERIC thhn10solblu500r is a 10 AWG solid plain copper conductor rated for general-purpose electrical wiring in residential, commercial, and light industrial applications. The conductor is insulated with PVC and jacketed with nylon, meeting THHN/THWN-2 construction standards. Rated at 600 volts, this wire handles up to 30 amps at 90 degrees C in dry conditions and 20 amps at 75 degrees C in wet conditions. The blue insulation color supports circuit identification during installation. Each spool contains 500 feet of continuous conductor, reducing the need for mid-run splices on longer pulls.

This wire is suited for use in conduit runs in residential service panels, commercial branch circuits, and industrial control wiring where a solid 10 AWG conductor is specified. Solid construction is commonly selected for shorter runs, conduit installations, and applications where the conductor will be terminated at devices such as receptacles, breakers, or disconnect panels. Licensed electricians install this wire in both new construction and retrofit work governed by the National Electrical Code (NEC).

Key Features

• 10 AWG solid plain copper conductor for reliable conductivity and straightforward termination
• 600-volt rating suitable for standard branch circuit and feeder wiring
• 90 degrees C dry / 75 degrees C wet temperature ratings for broad installation flexibility
• PVC insulation with nylon jacket for abrasion resistance and smooth conduit pulling
• Blue insulation color for circuit identification and NEC color-coding practices
• 500-foot spool length minimizes splices on extended conduit runs

Compatibility

Designed as a standard THHN-rated 10 AWG solid copper conductor suitable for use in conduit or raceway systems in residential, commercial, and light industrial electrical installations where NEC-compliant 600-volt wire is required.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code and all applicable local codes. De-energize and lock out the circuit or panel before making any connections. Solid 10 AWG conductors are intended for conduit or raceway installation and are not recommended for applications requiring frequent flexing. Verify ampacity derating requirements when bundling multiple conductors in the same conduit.
