Thhncu-generic thhn3/0strredmr Thhn 3/0 Awg Red Copper Wire

Product Description

The THHNCU-GENERIC thhn3/0strredmr is a 3/0 AWG stranded copper THHN building wire with red PVC insulation and a nylon jacket, rated for 600 volts. It carries a temperature rating of 90 degrees C in dry environments and is available cut to length for job-specific pulls. With 19-strand construction, this wire offers flexibility suited for conduit runs in commercial and residential electrical installations. Licensed electricians specify this wire for branch circuit, feeder, and service entrance applications where a large-gauge conductor is required. The copper conductor and dual-layer insulation meet standard NEC requirements for THHN-rated wire.

This wire is used in conduit in both residential and commercial settings. Common applications include feeder runs to subpanels, large motor circuits, and service entrance conductors where 3/0 AWG copper is called out on the load schedule. The red insulation aids phase identification in multi-conductor conduit pulls. It is well suited for indoor dry locations and is typically installed by licensed electricians on projects governed by NEC Article 310.

Key Features

• 3/0 AWG stranded copper conductor with 19-strand construction for conduit flexibility
• Ampacity rated at 165 amps at 60 degrees C, 200 amps at 75 degrees C, and 225 amps at 90 degrees C
• 600-volt rating covers standard branch circuit and feeder applications
• PVC insulation with nylon jacket meets THHN type listing requirements
• Red insulation color supports phase identification in multi-wire pulls
• Cut-to-length ordering reduces jobsite waste on specific conduit runs

Compatibility

Designed as an OEM-style replacement or direct-use THHN building wire for conduit-fed electrical systems requiring 3/0 AWG copper conductors rated at 600 volts.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC Article 310 and applicable local codes. De-energize all circuits and verify absence of voltage before pulling or terminating wire. Use appropriate wire-pulling lubricant and conduit fill calculations per NEC Chapter 9 when routing through conduit. Terminate only with connectors and lugs rated for the conductor size and material.
