Thhncu-generic thhn1stryelmr 1 Awg Thhn Copper Wire Yellow

Product Description

The THHNCU-GENERIC thhn1stryelmr is a 1 AWG stranded copper THHN building wire rated for 600 volts and up to 150 amps at 90 degrees C. The conductor is made from copper with a 19-strand configuration for flexibility during pull-in. Insulation is yellow PVC with a nylon jacket, meeting THHN dry-location ratings. This wire is sold cut to length, making it practical for commercial and residential electrical work where specific run lengths are needed. Electricians use this gauge for feeder circuits, service entrance applications, and large branch circuits requiring high ampacity.

This wire is suited for installation in conduit in dry locations, including commercial buildings, industrial facilities, and residential service panels. The 1 AWG size handles demanding feeder and sub-feeder runs where high current capacity is required. The yellow insulation color aids in circuit identification during installation and future service work. Cut-to-length availability reduces waste on job sites with specific footage requirements.

Compatibility

Designed for use in conduit systems requiring 1 AWG THHN copper building wire rated at 600 volts in dry locations, conforming to NEC ampacity tables for copper conductors.

Installation Notes

Installation of 1 AWG THHN wire must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit or panel before terminating conductors. Pull wire through conduit using appropriate pulling lubricant to avoid jacket damage. Verify termination points are rated for 90 degrees C conductors if applying the full ampacity rating.
