Thhncu-generic thhn1/0stryelmr Thhn 1/0 Awg Copper Wire

Product Description

The THHNCU-GENERIC thhn1/0stryelmr is a 1/0 AWG stranded copper THHN wire with yellow PVC insulation and a nylon jacket, rated for 600 volts and up to 90 degrees C in dry environments. The conductor is built from 19 strands of copper, giving it flexibility for conduit pulls in tight or long runs. Ampacity is 125 amps at 60 degrees C, 150 amps at 75 degrees C, and 170 amps at 90 degrees C, making it suitable for branch circuits, feeders, and service entrance wiring where load demands are substantial. It is sold cut to length, which reduces scrap on jobs that require precise footage.

This wire is used in residential and commercial electrical installations wherever THHN conductors are specified. Common applications include panel feeders, motor circuits, and conduit runs in dry locations. The yellow insulation color aids phase identification and code-compliant color coding in multi-conductor installations. Electricians working on service upgrades, sub-panel feeds, and large appliance circuits will find this conductor a standard fit for NEC-governed work requiring a 600-volt rated THHN conductor at the 1/0 AWG size.

Key Features

• 1/0 AWG stranded copper conductor with 19-strand configuration for flexibility in conduit
• Ampacity ratings: 125 amps at 60 degrees C, 150 amps at 75 degrees C, 170 amps at 90 degrees C
• 600-volt rating suitable for branch circuit and feeder applications
• PVC insulation with nylon jacket meets THHN specification requirements
• Yellow insulation for phase identification in multi-conductor wiring
• Cut-to-length availability reduces material waste on custom-footage jobs

Compatibility

Designed as a standard THHN conductor for use in conduit or raceways in dry locations per NEC requirements for 600-volt rated wiring at the 1/0 AWG size.

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 any connections. Use appropriately rated conduit, connectors, and termination lugs sized for 1/0 AWG conductors. Do not exceed the temperature rating of the termination points, as connector ratings may limit the usable ampacity below the wire's rated capacity.
