Thhncu-generic thhn4strgrnmr Thhn 4 Awg Green Copper Wire

Product Description

The THHNCU-GENERIC thhn4strgrnmr is a 4 AWG stranded copper THHN building wire with green PVC insulation and a nylon jacket, sold cut to length. This wire carries a 600-volt rating and a 90 degrees C dry temperature rating, making it suitable for branch circuits, feeder runs, and equipment grounding applications in conduit. Current capacity is 70 amps at 60 degrees C, 85 amps at 75 degrees C, and 100 amps at 90 degrees C. The 19-strand construction provides flexibility during pull-through in conduit compared to solid conductors. Licensed electricians and electrical contractors are the primary installers of this wire type.

This wire is used in residential, commercial, and light industrial electrical installations where NEC-compliant THHN wire is required in conduit or raceway systems. The green insulation color identifies this conductor as an equipment grounding conductor per NEC convention. Typical applications include panel feeders, motor circuits, and grounding runs where conduit-routed copper wire is specified. It ships cut to the ordered length, reducing waste on job sites where specific footage is needed.

Key Features

• 4 AWG copper conductor with 19-strand construction for flexible conduit pulls
• Green PVC insulation with nylon jacket meets THHN type designation
• 600-volt rated for standard branch circuit and feeder applications
• 90 degrees C dry temperature rating for maximum ampacity of 100 amps
• Green insulation color identifies equipment grounding conductor per NEC convention
• Cut-to-length ordering reduces on-site waste

Compatibility

Designed for use in conduit or raceway systems where NEC-compliant THHN copper building wire is specified. Suitable for residential, commercial, and light industrial branch circuit and feeder installations requiring a 4 AWG equipment grounding or current-carrying conductor.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit or panel before terminating or pulling wire. THHN wire must be installed in conduit or a listed raceway and is not rated for direct burial or wet locations without additional protection. Use appropriate wire pulling lubricant for long conduit runs to avoid damaging the insulation jacket.
