Thhncu-generic thhn4strredmr Thhn 4 Awg Red Copper Wire

Product Description

The THHNCU-GENERIC thhn4strredmr is a 4 AWG stranded copper THHN building wire with red PVC insulation and a nylon jacket, sold cut to length. It carries a 600-volt rating and a 90 degrees C dry temperature rating. Current capacity varies by installation method: 70 amps at 60 degrees C, 85 amps at 75 degrees C, and 100 amps at 90 degrees C. The 19-strand construction provides flexibility for pulling through conduit runs in commercial and residential electrical installations. Licensed electricians use this wire for branch circuits, feeders, and general wiring in conduit systems governed by the NEC.

This wire is suited for use in dry locations inside conduit, raceway, or cable tray. The 4 AWG size and 100-amp capacity at 90 degrees C make it a common choice for subpanel feeders, motor branch circuits, and large appliance circuits in both residential and light commercial settings. The red insulation color aids phase identification and circuit tracing during installation and maintenance. At 152 pounds per thousand feet, contractors should account for spool weight when planning pulls on longer runs.

Key Features

• 4 AWG stranded copper conductor with 19-strand configuration for pull flexibility
• 100-amp capacity at 90 degrees C dry rating
• 600-volt insulation rating suitable for standard building wiring applications
• PVC insulation with nylon jacket for abrasion resistance in conduit
• Red insulation color for phase identification per NEC color conventions
• Cut-to-length availability reduces waste on custom-length conduit runs

Compatibility

Designed for use in conduit, raceway, or cable tray installations requiring 4 AWG THHN building wire rated at 600 volts in dry environments per NEC Article 310 standards.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the circuit before making any terminations. THHN wire is rated for dry locations only and must be run inside conduit, raceway, or cable tray — it is not approved for direct burial or wet locations without additional protection. Use appropriately rated connectors and terminals sized for 4 AWG conductors to ensure proper torque and mechanical integrity at all termination points.
