Thhncu-generic thhn3stryelmr 3 Awg Thhn Copper Wire Yellow

Product Description

The THHNCU-GENERIC thhn3stryelmr is a 3 AWG stranded copper THHN wire with yellow PVC insulation and a nylon jacket, sold cut to length. Rated at 600 volts and up to 90 degrees C in dry environments, this conductor is built for branch circuit wiring, feeder runs, and general electrical distribution work inside conduit. With 19-strand construction, it offers good flexibility for pulling through conduit compared to solid conductor wire. Current capacity ranges from 85 amps at 60 degrees C to 115 amps at 90 degrees C, making it suitable for high-amperage branch and feeder applications in both residential and commercial settings.

This wire is used in commercial and residential electrical installations where conductors are pulled through conduit — EMT, rigid metal, or PVC. The yellow insulation color supports phase identification and color-coded wiring practices on multi-wire circuits. It is installed by licensed electricians in panels, sub-panels, motor feeders, and large appliance circuits. The cut-to-length format reduces jobsite waste and is well suited for service work and retrofit projects where a specific run length is needed rather than a full reel.

Key Features

• 3 AWG, 19-strand copper conductor for flexibility during conduit pulls
• 600-volt rating covers the majority of branch circuit and feeder applications
• 90 degrees C dry rating supports 115-amp capacity at maximum rated temperature
• PVC insulation with nylon jacket meets THHN requirements for conduit use
• Yellow insulation for consistent phase identification and NEC color-coding practices
• Cut-to-length format minimizes waste on service calls and retrofit installs

Compatibility

Designed for use in dry conduit installations requiring a 3 AWG THHN-rated copper conductor at 600 volts. Suitable for branch circuits, motor feeders, and general-purpose feeder wiring in residential and commercial electrical systems where NEC-compliant THHN wire is specified.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before terminating or splicing. THHN wire is rated for conduit use in dry locations only — do not use in wet or direct-burial applications without a wet-rated insulation system. Use appropriate wire connectors and torque terminal screws to the equipment manufacturer's listed values.
