Thhncu-generic thhn8stryel1000r Thhn 8 Awg Stranded Wire

Product Description

The THHNCU-GENERIC thhn8stryel1000r is a 1000-foot reel of 8 AWG stranded copper building wire with THHN insulation in yellow. The conductor is made up of 19 strands of copper, giving it flexibility for routing through conduit in commercial and residential electrical installations. PVC insulation is bonded with a nylon jacket, which provides the abrasion resistance and moisture protection required for the THHN designation. The wire is rated at 600 volts and carries a temperature rating of 90 degrees C in dry environments. Ampacity is 40 amps at 60 degrees C, 50 amps at 75 degrees C, and 55 amps at 90 degrees C depending on the installation method and ambient temperature correction. Licensed electricians specify this wire for general-purpose branch circuit and feeder wiring in conduit.

This wire is used in residential, commercial, and light industrial electrical systems where conductors must be pulled through conduit or raceways. Yellow insulation is commonly used for circuit color-coding to distinguish conductors by phase or circuit in multi-wire systems. Typical applications include branch circuit wiring, panel feeders, and general-purpose power distribution runs. The 1000-foot reel format is suited for large job sites or contractors who need continuous pulls without splices. Electricians working under the NEC will find this wire appropriate for conduit-installed applications where THHN is an approved wiring method.

Key Features

• 8 AWG copper conductor with 19-strand configuration for improved flexibility during conduit pulls
• THHN-rated PVC insulation with nylon jacket for abrasion and moisture resistance
• 90 degrees C dry temperature rating at 600 volts
• Ampacity up to 55 amps at 90 degrees C depending on installation conditions
• Yellow insulation for conductor identification and circuit color-coding
• 1000-foot reel format minimizes splice points on long runs

Compatibility

Designed for use in conduit and raceway wiring systems where THHN is an approved conductor type under NEC guidelines. Suitable for 8 AWG applications in residential, commercial, and light industrial branch circuit and feeder installations.

Installation Notes

Installation of building wire should be performed by a licensed electrician in accordance with the National Electrical Code and applicable local codes. De-energize and lock out all circuits before pulling or terminating conductors. Use appropriate conduit pull lubricant for long runs to avoid insulation damage during the pull. Verify ampacity correction factors for conduit fill, ambient temperature, and bundling conditions before sizing overcurrent protection.
