Thhncu-generic thhn8strred500r Thhn 8 Awg Copper Wire 500 Ft

Product Description

The THHNCU-GENERIC thhn8strred500r is a 500-foot reel of 8 AWG stranded copper THHN building wire with red PVC insulation and a nylon jacket. Rated at 600 volts and 90 degrees C for both dry and wet locations, this wire is a standard choice for branch circuit wiring, feeder runs, and general electrical distribution work. The 19-strand configuration provides flexibility during pull-through conduit installations. Current capacity is 40 amps at 60 degrees C, 50 amps at 75 degrees C, and 55 amps at 90 degrees C, making it suitable for a range of load calculations under NEC ampacity tables. Licensed electricians and electrical contractors are the primary installers.

This wire is used in residential, commercial, and light industrial electrical installations where THHN-rated conductors are required by code. Typical applications include conduit runs in panel feeders, sub-panel wiring, motor circuit conductors, and general branch circuit wiring. The red insulation color aids in phase identification and conductor tracing during installation and service. The 500-foot reel length suits medium to large jobs where continuous runs reduce the need for splices.

Key Features

• 8 AWG stranded copper conductor with 19-strand configuration for flexibility in conduit
• THHN-rated insulation: 600-volt, 90 degrees C rated for dry and wet environments
• PVC insulation with nylon jacket for abrasion resistance and pull-through ease
• Red insulation color for phase identification per standard color-coding practice
• Ampacity up to 55 amps at 90 degrees C per NEC tables
• 500-foot continuous reel minimizes splices on longer runs

Compatibility

Designed for use in conduit systems where THHN or THWN-2 rated 8 AWG copper conductors are specified. Suitable for NEC-compliant branch circuit and feeder wiring in residential, commercial, and light industrial conduit installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements and applicable local codes. Always de-energize the circuit and verify zero voltage with a meter before making any connections. THHN wire must be pulled through conduit rather than run exposed; use appropriate wire-pulling lubricant to reduce friction on longer runs and protect the nylon jacket. Do not exceed the conductor ampacity ratings for the applicable temperature column based on the termination rating of the connected equipment.
