Thhncu-generic thhn3/0stryelmr Thhn 3/0 Awg Yellow Copper Wire

Product Description

The THHNCU-GENERIC thhn3/0stryelmr is a 3/0 AWG stranded copper THHN building wire with yellow PVC insulation and a nylon jacket, rated for 600 volts and 90 degrees C in dry locations. Supplied cut to length, this wire is suited for branch circuit, feeder, and service entrance wiring in conduit. The 19-strand configuration provides flexibility during pull-through, and the nylon jacket reduces friction against conduit walls. Licensed electricians specify this wire for load centers, panelboards, and commercial distribution runs where ampacity and temperature rating are primary selection criteria.

THHN 3/0 AWG copper wire is used in residential, commercial, and light industrial electrical installations. It is pulled through conduit in service panels, sub-panels, and feeder runs. The yellow insulation color aids in phase identification and circuit tracing during installation and maintenance. This cut-to-length format reduces on-site waste and is ordered to the exact footage needed for a given run.

Key Features

• 3/0 AWG stranded copper conductor with 19-strand configuration for pull flexibility
• Ampacity rated at 165 amps at 60 degrees C, 200 amps at 75 degrees C, and 225 amps at 90 degrees C
• 600-volt rating suitable for standard branch circuit and feeder applications
• PVC insulation with nylon jacket for conduit pull ease and abrasion resistance
• Yellow insulation for phase identification in multi-conductor conduit runs
• Cut-to-length format minimizes scrap on job sites

Compatibility

Designed for use in conduit as THHN-rated building wire in standard NEC-compliant electrical installations requiring 3/0 AWG copper conductor.

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 terminations. Use appropriately rated connectors and lugs sized for 3/0 AWG copper. Do not exceed the published ampacity values for the installation ambient temperature and conduit fill conditions per NEC tables.
