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

Product Description

The THHNCU-GENERIC thhn3/0strbrnmr is a 3/0 AWG stranded copper conductor THHN wire with brown PVC insulation and a nylon jacket, rated for 600 volts and 90 degrees C in dry environments. Constructed with 19 strands for flexibility, it carries up to 225 amps at 90 degrees C, making it well suited for high-ampacity branch circuit, feeder, and service applications. Licensed electricians install this wire in conduit systems for commercial and residential projects where NEC-compliant conductors are required. It is sold cut to length, allowing job-specific footage without excess material waste.

This wire is used in conduit runs for load centers, panel feeders, motor circuits, and large appliance branch circuits where 3/0 AWG conductors are specified. The brown insulation color supports phase identification in multi-conductor installations. It is appropriate for dry locations in commercial, industrial, and residential electrical systems. Electricians working under NEC Article 310 conductor sizing requirements will find this wire meets standard ampacity table values for THHN insulation types.

Key Features

• 3/0 AWG stranded copper conductor with 19-strand configuration for flex and pull-through ease
• Brown PVC insulation with nylon jacket rated THHN for dry conduit installations
• 600-volt rating suitable for standard branch circuit and feeder applications
• Temperature ratings of 165 amps at 60 degrees C, 200 amps at 75 degrees C, and 225 amps at 90 degrees C
• Cut-to-length availability reduces scrap on job-specific conduit runs
• Outer diameter of 568 mil for conduit fill calculations

Compatibility

Designed for use in conduit systems where THHN-rated 3/0 AWG stranded copper conductors are specified per NEC ampacity and installation requirements for dry locations at up to 600 volts.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the circuit before pulling or terminating conductors. THHN wire is listed for use in conduit only and is not rated for direct burial or wet locations without an additional rating. Verify conduit fill percentages per NEC Chapter 9 before pulling multiple conductors through the same raceway.
