Thhncu-generic thhn3/0strwhtmr Thhn 3/0 Awg Copper Wire

Product Description

The THHNCU-GENERIC thhn3/0strwhtmr is a 3/0 AWG stranded copper conductor wire rated for 600 volts and up to 90 degrees C in dry installations. The conductor is built with 19 strands for flexibility during pull-through and termination work. Insulation is PVC thermoplastic with a nylon jacket, meeting THHN type specifications. Ampacity is rated at 165 amps at 60 degrees C, 200 amps at 75 degrees C, and 225 amps at 90 degrees C. This wire is sold cut to length, making it practical for service entrance work, panel feeds, feeder runs, and large branch circuit applications where a specific footage is needed rather than a full reel.

This wire is suited for commercial and residential electrical installations requiring a large-gauge feeder or service conductor. Common applications include main panel feeds, subpanel runs, motor circuits, and service entrance wiring where a white-insulated 3/0 conductor is specified. The white insulation color supports neutral identification or color-coded phase marking per NEC guidelines when field-re-identified. Licensed electricians and electrical contractors are the primary installers of wire at this gauge.

Key Features

• 3/0 AWG stranded copper conductor with 19-strand construction for flexibility
• Rated 600 volts for standard power distribution applications
• THHN type with PVC thermoplastic insulation and nylon jacket
• Temperature rating of 90 degrees C dry, with ampacity up to 225 amps at 90 degrees C
• White insulation color for neutral or field-identified phase conductors
• Sold cut to length to reduce waste and match job-specific footage needs

Compatibility

Designed as a standard THHN-type 3/0 AWG stranded copper conductor suitable for use in conduit systems and raceways where THHN or THWN-2 rated wire is specified.

Installation Notes

Installation of 3/0 AWG conductors must 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 terminating or splicing conductors. Wire at this gauge typically requires a wire puller, pulling lubricant, and appropriate conduit fill calculations before installation. Verify connector and lug ratings match the conductor size and termination temperature rating before making connections.
