Thhncu-generic thhn4/0strorgmr Thhn 4/0 Awg Copper Wire

Product Description

The THHNCU-GENERIC thhn4/0strorgmr is a 4/0 AWG stranded copper THHN wire with orange PVC insulation and a nylon jacket, rated for 600 volts and 90 degrees C in dry environments. Constructed with a 19-strand copper conductor, it delivers an ampacity of 195 amps at 60 degrees C, 230 amps at 75 degrees C, and 260 amps at 90 degrees C. This wire is sold cut to length, making it practical for job-site pulls where custom footage is needed. Licensed electricians install this wire in conduit systems for feeders, branch circuits, and service entrance applications where a color-coded, high-temperature-rated conductor is required.

This 4/0 AWG THHN wire is suited for commercial and residential electrical installations where conductors are pulled through conduit or raceways. The orange insulation provides clear color identification for phase or circuit labeling on larger feeder runs. Its stranded 19-strand construction improves flexibility during conduit pulls compared to solid conductors, reducing the effort required on long or complex runs. Electricians and electrical contractors working on panel feeds, switchgear connections, and large motor circuits will find this gauge appropriate for high-ampacity applications.

Key Features

• 4/0 AWG stranded copper conductor with 19-strand construction for improved pull flexibility
• Rated 600 volts with a 90 degrees C dry temperature rating
• Ampacity of 260 amps at 90 degrees C, 230 amps at 75 degrees C, and 195 amps at 60 degrees C
• Orange PVC insulation with nylon jacket for abrasion resistance and ease of conduit installation
• Cut-to-length availability reduces waste on custom feeder and branch circuit pulls
• Outer diameter of 624 mil for conduit fill calculations

Compatibility

Designed for use in conduit, raceways, and cable trays per NEC requirements for THHN-rated conductors in dry locations. Suitable for feeder and branch circuit wiring in residential, commercial, and light industrial electrical systems.

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 or panel before making connections. Verify conduit fill calculations using the 624 mil outer diameter prior to pulling. THHN wire is rated for dry locations only; do not install in wet or damp locations without a wire type rated for those conditions.
