Thhn 4/0 Awg Stranded Copper Wire 600V White Cut to Length

Product Description

The THHNCU-GENERIC thhn4/0strwhtmr is a 4/0 AWG stranded copper THHN wire with white PVC thermoplastic insulation and a nylon jacket, rated for 600 volts and up to 260 amps at 90 degrees C in dry conditions. The 19-strand configuration provides flexibility during pull-in, making it a practical choice for conduit installations in commercial and residential service entrance, feeder, and branch circuit applications. This wire is sold cut to length, allowing electricians to order exactly what a job requires without dealing with full reels. The outer diameter measures 624 mil, which is relevant for conduit fill calculations under NEC requirements.

This wire is suited for use in dry locations where THHN-rated conductors are required by code. Typical applications include panel feeders, service entrance conductors, motor branch circuits, and general building wiring pulled through EMT, rigid metal, or PVC conduit. The white insulation color supports color-coding practices used in large-conductor installations. It is appropriate for commercial and industrial environments as well as large residential service work where 4/0 AWG feeders are called for.

Key Features

• 4/0 AWG copper conductor with 19-strand configuration for pull-in flexibility
• Ampacity ratings: 195 amps at 60 degrees C, 230 amps at 75 degrees C, 260 amps at 90 degrees C
• 600-volt rated insulation for standard building wiring applications
• PVC thermoplastic insulation with nylon jacket for abrasion and moisture resistance
• White insulation color for conductor identification in large-gauge feeder work
• Cut-to-length format reduces waste and simplifies job-site ordering

Compatibility

Designed for use in conduit systems where THHN 4/0 AWG copper conductors are specified, including EMT, rigid metal conduit, and PVC conduit installations in dry-rated environments per NEC guidelines.

Installation Notes

Installation of 4/0 AWG feeder conductors is typically performed by licensed electricians. De-energize and lock out the panel or service disconnect before making terminations. Use a cable pulling lubricant rated for THHN insulation when pulling through long conduit runs or those with multiple bends. Conduit fill calculations must comply with NEC Chapter 9 tables for the specific conduit type and size in use.
