Thhncu-generic thhn600mcmstrredmr Thhn 600 Kcmil Copper Wire

Product Description

The THHNCU-GENERIC thhn600mcmstrredmr is a 600 kcmil stranded copper THHN wire with red PVC insulation and a nylon jacket, sold cut to length. It carries a 600-volt rating and a 90 degrees C dry temperature rating. Current capacity is 350 amps at 60 degrees C, 420 amps at 75 degrees C, and 475 amps at 90 degrees C. The 61-strand configuration provides flexibility suited to large feeder and service-entrance pulls. Electricians and electrical contractors use this wire in commercial and industrial installations where high-ampacity conductors are required in conduit.

This wire is used in large feeder runs, service-entrance work, and branch circuits requiring heavy-gauge copper conductors. The red insulation supports phase identification in multi-conductor installations per NEC color-coding conventions. It is appropriate for dry conduit runs in commercial buildings, industrial facilities, and utility applications. The cut-to-length format reduces job-site waste and allows procurement matched to exact run distances.

Key Features

• 600 kcmil copper conductor with 61-strand construction for flexibility on long pulls
• Rated 475 amps at 90 degrees C, 420 amps at 75 degrees C, and 350 amps at 60 degrees C
• 600-volt insulation rating with PVC thermoplastic over nylon jacket
• Red insulation for phase identification in multi-conductor feeder systems
• Outer diameter of 1,024 mil supports conduit fill calculations
• Available cut to length to minimize waste on large feeder projects

Compatibility

Designed for use in conduit systems requiring THHN-rated large-gauge copper feeder or service-entrance conductors in dry environments rated to 600 volts.

Installation Notes

Installation of 600 kcmil feeder conductors is typically performed by licensed electricians following NEC Article 310 and applicable local codes. De-energize all circuits and verify lockout/tagout procedures before beginning work. Large-gauge conductors of this size require wire-pulling equipment, appropriate conduit fill calculations, and compatible lugs or compression terminations rated for the conductor size. Do not exceed the temperature rating of connected termination hardware.
