Thhncu-generic thhn8strgrn500r Thhn 8 Awg Green Wire 500 Ft

Product Description

The THHNCU-GENERIC thhn8strgrn500r is an 8 AWG stranded copper THHN building wire with green PVC insulation and a nylon jacket, supplied on a 500-foot reel. It is rated for 600 volts and carries a 90 degrees C dry temperature rating, making it suitable for branch circuit wiring in conduit runs across commercial and residential applications. The 19-strand configuration provides flexibility during pulls through conduit. Ampacity is 40 amps at 60 degrees C, 50 amps at 75 degrees C, and 55 amps at 90 degrees C. Licensed electricians and electrical contractors are the primary installers of this wire type.

This wire is used in conduit installations for branch circuits, feeder runs, and equipment grounding applications where green-insulated conductors are required by code to identify equipment grounding conductors. The 500-foot reel length is practical for commercial rough-in work, panel feeds, and multi-circuit pulls. Its THHN rating makes it appropriate for dry locations inside conduit or raceways.

Key Features

• 8 AWG stranded copper conductor with 19-strand configuration for pull flexibility
• THHN-rated PVC insulation with nylon jacket for abrasion resistance in conduit
• 600-volt rating supports standard branch circuit and feeder applications
• 90 degrees C dry temperature rating with three ampacity tiers: 40A, 50A, and 55A
• Green insulation color for equipment grounding conductor identification per NEC requirements
• 500-foot reel reduces waste and simplifies job-site inventory management

Compatibility

Designed for use in conduit or raceway systems where THHN-rated building wire is specified for dry locations, suitable for residential, commercial, and light industrial electrical installations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits and verify with a meter before beginning any wire termination work. THHN wire must be installed inside an approved conduit or raceway and is not rated for direct burial or wet locations without an additional wet-location-rated outer jacket. Use appropriate wire pulling lubricant and conduit fill calculations when routing through conduit to avoid insulation damage.
