Thhncu-generic thhn8strgrnmr 8 Awg Green Thhn Copper Wire

Product Description

The THHNCU-GENERIC thhn8strgrnmr is a THHN-rated, 8 AWG stranded copper building wire with green PVC insulation and a nylon jacket. It is designed for use in conduit in commercial and residential electrical systems where a 600-volt rated conductor is required. The 19-strand configuration provides flexibility during pull-in, reducing kinking in tight conduit runs. Ampacity is rated at 40 amps at 60 degrees C, 50 amps at 75 degrees C, and 55 amps at 90 degrees C, making it suitable for branch circuits and feeder applications where the installation environment and termination ratings dictate the usable ampacity. Licensed electricians are the primary installers of this conductor.

This wire is sold cut to length and is appropriate for installation in dry locations inside conduit, cable trays, or raceways. The green insulation identifies it as an equipment grounding conductor per NEC color-code conventions, making it the standard choice for grounding runs in panelboards, switchgear, and equipment branch circuits. It is commonly used in light commercial buildouts, industrial panels, and residential service work where a flexible, code-compliant ground conductor is needed at the 8 AWG size.

Key Features

• 8 AWG, 19-strand copper conductor for flexibility during conduit installation
• Green PVC insulation with nylon jacket meets THHN specification
• Rated 600 volts for standard branch circuit and feeder applications
• Temperature rating of 90 degrees C in dry environments
• Ampacity up to 55 amps at 90 degrees C depending on installation conditions
• Sold cut to length to reduce waste on the job

Compatibility

Designed as a standard THHN-rated equipment grounding conductor for use in conduit-based wiring systems in residential, commercial, and light industrial applications where 8 AWG green grounding wire is specified.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the circuit before terminating or splicing this conductor. THHN wire is rated for dry locations inside conduit and is not approved for direct burial or wet locations without an additional rated outer jacket. Verify that all terminations and lugs are rated for the conductor size and temperature class being used before making connections.
