Thhn 600 Kcmil Stranded Copper Wire Orange 600V

Product Description

The THHNCU-GENERIC thhn600mcmstrorgmr is a 600 KCMIL stranded copper conductor wire rated for use in a wide range of commercial and industrial electrical installations. Built with 61-strand copper construction and insulated with PVC thermoplastic plus a nylon jacket, this wire carries a 600-volt rating and a 90 degrees C dry temperature rating. Ampacity is 350 amps at 60 degrees C, 420 amps at 75 degrees C, and 475 amps at 90 degrees C. The orange insulation color supports color-coded conduit runs and phase identification on larger service feeders and distribution systems.

This wire is suited for use in conduit on commercial feeders, industrial power distribution, service entrance applications, and large mechanical equipment connections. The THHN type designation means it is intended for dry locations and must be pulled through conduit or raceway per NEC requirements. Its large conductor size makes it a common choice for main distribution panels, motor feeders, and heavy electrical service runs in commercial and industrial buildings. Licensed electricians typically handle installation at this conductor size.

Key Features

• 600 KCMIL copper conductor with 61-strand construction for flexibility during conduit pulls
• PVC thermoplastic insulation with nylon jacket for abrasion and moisture resistance
• Rated 475 amps at 90 degrees C for high-capacity feeder applications
• 600-volt rating suitable for standard commercial and industrial distribution voltages
• Orange insulation for phase identification and color-coded conduit systems
• THHN type rating for dry location conduit and raceway installations

Compatibility

Designed for use in conduit and raceway systems as a THHN-rated copper feeder or branch-circuit conductor in commercial and industrial electrical installations per NEC Article 310 guidelines.

Installation Notes

Installation of 600 KCMIL conductors 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 terminating or splicing. Wire pulling lubricant is recommended for long conduit runs at this conductor size to avoid jacket damage. Verify termination lugs and equipment are rated for 600 KCMIL aluminum or copper conductors before making connections.
