Thhn 3 Awg Stranded Black Copper Wire 600V 5000 Ft

Product Description

The THHN-GENERIC thhn3strblkmr is a 3 AWG stranded copper conductor wire rated for general wiring applications in commercial and residential construction. Built with a 19-strand copper conductor, PVC insulation, and a nylon jacket, this wire carries a 600-volt rating and a 90 degrees C temperature rating for both dry and wet environments. Ampacity is 85 amps at 60 degrees C, 100 amps at 75 degrees C, and 115 amps at 90 degrees C. The black insulation color aids in circuit identification during installation. This product is sold by the spool and cut to length as specified at order.

THHN wire in 3 AWG is commonly used for branch circuit wiring, feeder runs, and service entrance applications in conduit. It is suitable for use in commercial buildings, industrial facilities, and residential service upgrades where NEC-compliant conductors are required. Electricians pull this wire through conduit systems including EMT, rigid metal, and PVC conduit. The nylon jacket reduces friction during conduit pulls and provides added resistance to oils and solvents encountered in industrial environments.

Key Features

• 3 AWG, 19-strand copper conductor for flexibility during installation and conduit pulls
• Dual-rated THHN insulation suitable for dry and wet locations up to 90 degrees C
• 600-volt rating covers standard branch circuit and feeder wiring requirements
• Nylon outer jacket reduces pull friction and resists common industrial contaminants
• Black insulation color supports NEC-compliant circuit identification
• Available cut to length from a 5000-foot spool to reduce waste on large jobs

Compatibility

Designed for use in conduit systems as a THHN-rated conductor per NEC guidelines for residential, commercial, and light industrial branch circuit and feeder wiring applications.

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 all circuits before making connections. Use appropriate wire-pulling lubricant when routing through conduit to avoid jacket damage. Verify conduit fill calculations per NEC Chapter 9 before pulling multiple conductors.
