Thhncu-generic thhn8strorgmr Thhn 8 Awg Stranded Copper Wire

Product Description

The THHNCU-GENERIC thhn8strorgmr is a THHN-rated, 8 AWG stranded copper conductor wire with orange PVC insulation and a nylon jacket, sold in cut-to-length quantities. It is rated for 600 volts and carries a 90 degrees C dry temperature rating. Ampacity is 40 amps at 60 degrees C, 50 amps at 75 degrees C, and 55 amps at 90 degrees C. The 19-strand construction provides flexibility over solid conductor alternatives, making it well suited for pulling through conduit in branch circuit and feeder applications. Licensed electricians and electrical contractors are the primary installers of this wire type.

This wire is used in residential, commercial, and light industrial wiring applications where THHN-rated conductors are required inside conduit or raceways. The orange insulation color supports color-coded wiring layouts, aiding circuit identification during installation and maintenance. It is appropriate for branch circuits, feeder runs, panel wiring, and general-purpose electrical installations where a 600-volt, 8 AWG conductor is specified. Cut-to-length availability reduces waste on job sites where standard reel lengths exceed project requirements.

Key Features

• 8 AWG conductor size with 19-strand copper construction for flexibility during conduit pulls
• 600-volt rating suitable for standard branch circuit and feeder applications
• 90 degrees C dry temperature rating with ampacity up to 55 amps
• Orange PVC insulation with nylon jacket for abrasion resistance inside conduit
• Cut-to-length format reduces material waste on smaller or custom-length runs

Compatibility

Designed as a standard THHN 8 AWG conductor for use inside conduit, wireways, or raceways in installations governed by NEC requirements for THHN-rated wire.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before making any connections. THHN wire is rated for use inside conduit or raceways and is not approved for direct burial or wet locations without an additional wet-rated jacket. Use appropriate wire-pulling lubricant when pulling through conduit to avoid damaging the insulation.
