Thhn 350 Mcm Stranded Copper Wire Gray Cut to Length

Product Description

The THHN-GENERIC thhn350mcmstrgrymr is a stranded copper conductor wire rated for THHN applications, available in a 350 MCM (350 kcmil) size with gray insulation. This wire is designed for use in conduit installations where high-capacity current carrying is required. The stranded construction provides flexibility during pulling and routing through conduit runs. Electricians and electrical contractors use this wire for branch circuit wiring, feeder runs, and service entrance applications in commercial and industrial settings. Cut-to-length availability reduces waste and suits job-specific requirements.

This 350 MCM stranded THHN wire is suited for commercial and industrial electrical installations where large-gauge conductors are required for high-ampacity feeder or branch circuit work. It is installed inside conduit — rigid metal, intermediate metal, or PVC conduit — in accordance with NEC requirements. The gray insulation color is commonly used for phase identification in multi-conductor installations. Licensed electricians typically specify and install wire of this gauge on commercial projects, large residential services, and industrial panels.

Key Features

• 350 MCM (350 kcmil) conductor size for high-ampacity applications
• Stranded copper construction for flexibility during conduit pulls
• Gray THHN insulation for phase identification in multi-conductor systems
• Cut-to-length format reduces material waste on the job
• Suitable for dry and damp locations per THHN rating

Compatibility

Designed as a standard THHN-rated stranded copper conductor for use in conduit installations meeting NEC requirements for 350 MCM wire applications.

Installation Notes

Installation of 350 MCM conductors should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before making any terminations or splices. Wire pulling lubricant is recommended when routing this gauge through conduit runs to prevent insulation damage. Verify terminal and lug ratings at connection points are rated for 350 MCM copper conductors before terminating.
