Thhncu-generic thhn6strblkmr Thhn 6 Awg Black Copper Wire

Product Description

The THHNCU-GENERIC thhn6strblkmr is a 6 AWG stranded copper THHN building wire with black PVC insulation and a nylon jacket, rated for 600 volts. The conductor is constructed from 19 strands of copper, providing flexibility compared to solid conductors of the same gauge. Current capacity is 55 amps at 60 degrees C, 65 amps at 75 degrees C, and 75 amps at 90 degrees C. The temperature rating reaches 90 degrees C in dry environments. This wire is used by licensed electricians in residential, commercial, and light industrial wiring applications where THHN-type conductors are required by code.

This 6 AWG black THHN wire is suited for branch circuit wiring, feeder runs, panel feeds, and general-purpose power distribution. The black insulation color is commonly used to identify hot conductors in single-phase and three-phase systems. It is appropriate for use in conduit or raceway systems in dry locations. The cut-to-length format allows installers to pull only the footage needed for a given job, reducing material waste on larger projects.

Key Features

• 6 AWG stranded copper conductor with 19-strand construction for improved flexibility
• Rated 75 amps continuous at 90 degrees C in dry installations
• 600-volt rating suitable for standard branch circuit and feeder applications
• Black PVC insulation with nylon jacket for abrasion resistance in conduit pulls
• 90 degrees C dry temperature rating meets NEC ampacity table requirements for THHN conductors
• Available cut to length from a 5000-foot master reel

Compatibility

Designed for use in conduit, wireways, and raceway systems as a THHN-rated building wire for general electrical distribution in dry locations per NEC guidelines.

Installation Notes

Installation must 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 or panel before making any connections. THHN wire is rated for use in conduit or raceway only — it is not rated for direct burial or wet locations without additional protection. Use appropriate wire connectors, lugs, and termination hardware rated for the conductor size and material.
