Thhn 8 Awg Stranded Copper Wire Gray 600V Cut to Length

Product Description

The THHNCU-GENERIC thhn8strgrymr is an 8 AWG stranded copper THHN building wire with gray PVC insulation and a nylon jacket, rated for 600 volts and 90 degrees C in both dry and wet environments. Constructed from 19-strand copper conductors, this wire delivers rated ampacity of 40 amps at 60 degrees C, 50 amps at 75 degrees C, and 55 amps at 90 degrees C. It is sold cut to length, making it practical for service entrance runs, panel feeds, feeder circuits, and branch circuit wiring where a specific footage is needed rather than a full reel.

This gray THHN wire is suited for residential and commercial electrical installations including conduit runs, junction box wiring, and equipment branch circuits. The gray insulation color aids in conductor identification within multi-wire conduit runs. Licensed electricians and electrical contractors install this wire in accordance with NEC requirements for THHN-rated conductors in wet or dry raceway systems.

Key Features

• 19-strand copper conductor provides flexibility for pulling through conduit
• PVC insulation with nylon jacket rated THHN for raceway and conduit use
• 600-volt rating suitable for standard power distribution circuits
• 90 degrees C temperature rating in dry and wet locations
• Gray insulation color supports conductor identification in multi-wire conduit runs
• Sold cut to length for job-site efficiency

Compatibility

Designed as a standard THHN-rated 8 AWG building wire for use in conduit or raceway systems where NEC-compliant copper conductors are required.

Installation Notes

Installation should be performed by a licensed electrician in compliance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits and verify with a meter before making connections. This wire is intended for use inside conduit or raceways and should not be installed as open air or direct burial wiring unless combined with a listed outer cable assembly rated for that application. Avoid pulling tensions and bend radii that exceed the conductor manufacturer guidelines for stranded copper wire.
