Thhncu-generic thhn12strred500r Thhn 12 Awg Stranded Copper Wire

Product Description

The THHNCU-GENERIC thhn12strred500r is a 12 AWG stranded copper THHN building wire rated for 600 volts and supplied on a 500-foot spool. The conductor is made up of 19 strands of copper, giving it the flexibility needed for pulling through conduit on commercial and residential installations. PVC insulation with a nylon jacket meets THHN specifications and handles temperatures up to 90 degrees C in dry locations and 75 degrees C in wet locations. The red jacket color supports standard color-coding practices for branch circuit identification. Electricians and electrical contractors reach for this wire on panel feeds, branch circuits, and general-purpose wiring runs.

This wire is suited for use in commercial, industrial, and residential electrical installations where THHN-rated conductors are required. Common applications include branch circuit wiring in conduit, panel board connections, motor feeds, and general-purpose power distribution. The 500-foot spool length is practical for larger jobs and reduces the need for mid-run splices. The 20-amp current rating at standard 60, 75, and 90 degrees C column ratings aligns with NEC ampacity tables for 12 AWG copper conductors.

Key Features

• 12 AWG stranded copper conductor with 19-strand configuration for improved flexibility during conduit pulls
• 600-volt rating suitable for standard branch circuit and feeder applications
• 90 degrees C dry and 75 degrees C wet temperature ratings meet THHN and THWN-2 application requirements
• PVC insulation provides resistance to moisture, heat, and common chemical exposure
• Red jacket supports NEC color-coding conventions for branch circuit phase identification
• 500-foot spool quantity reduces splices and suits larger commercial or multi-circuit residential jobs

Compatibility

Designed as a standard THHN-rated 12 AWG stranded copper building wire for use in conduit systems meeting NEC requirements for 600-volt or lower installations in dry and wet locations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit or panel before making any connections. THHN wire must be run inside an approved conduit or raceway — it is not rated for direct burial or open-air outdoor exposure without additional protection. Inspect the wire for nicks or insulation damage after pulling through conduit, as damage during the pull can compromise the insulation rating.
