Thhncu-generic thhn4stryelmr Thhn 4 Awg Yellow Copper Wire

Product Description

The THHNCU-GENERIC thhn4stryelmr is a 4 AWG stranded copper conductor rated for THHN applications in dry environments. The wire features a PVC thermoplastic insulation layer with a nylon jacket over a 19-strand copper core, providing flexibility during pull-through and resistance to abrasion. Voltage rating is 600 volts with a temperature rating of 90 degrees C in dry conditions. Current capacity varies by ambient temperature: 70 amps at 60 degrees C, 85 amps at 75 degrees C, and 100 amps at 90 degrees C. This wire is sold cut to length and is intended for installation by licensed electricians in conduit systems.

This wire is suited for use in residential, commercial, and light industrial electrical installations where THHN-rated conductors are required. Typical applications include branch circuit wiring, feeder runs, and panel connections routed through conduit. The yellow insulation color aids in circuit identification during installation and future service work. It is appropriate for dry locations in conduit or raceway installations where NEC-compliant THHN conductors are specified.

Key Features

• 4 AWG 19-strand copper conductor for flexibility in conduit pulls
• PVC thermoplastic insulation with nylon jacket for abrasion resistance
• 600-volt rating suitable for standard branch and feeder circuit applications
• 90 degrees C dry temperature rating with ampacity up to 100 amps
• Yellow insulation for easy circuit identification
• Sold cut to length to reduce waste on the job

Compatibility

Designed as an OEM-style replacement or direct-use THHN conductor for residential, commercial, and industrial conduit wiring systems requiring 4 AWG 600-volt rated wire.

Installation Notes

Installation must 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 before making any connections. This wire is rated for dry locations only and must be run in conduit or raceway as required by THHN installation standards. Do not use in wet or direct-burial applications without a wire type rated for those conditions.
