Thhn 14 Awg Solid Copper Wire Black 500 Ft 600V thhn14solblk500r

Product Description

The THHNCU-GENERIC thhn14solblk500r is a 14 AWG solid plain copper conductor with black PVC insulation and a nylon jacket, rated for 600 volts and packaged on a 500-foot spool. This wire carries a 15-amp current rating and is rated to 90 degrees C in dry environments and 75 degrees C in wet environments, making it suitable for a wide range of branch circuit and general wiring applications. The THHN designation indicates thermoplastic high heat-resistant nylon-jacketed construction, a widely accepted specification for commercial and residential electrical work. Licensed electricians select this wire for conduit runs where a code-compliant, listed conductor is required.

This 14 AWG THHN wire is used in residential and light commercial electrical installations, primarily pulled through conduit for branch circuits, panel feeders, and general-purpose wiring. The solid construction makes it well suited for shorter conduit runs and applications where flexibility is not a primary requirement. The black insulation color identifies this conductor as a hot leg in standard single-phase wiring conventions. The 500-foot spool length supports full-run pulls on typical residential jobs without mid-run splices.

Key Features

• 14 AWG solid plain copper conductor — 15-amp rated branch circuit wire
• 600-volt rating suitable for standard residential and light commercial circuits
• 90 degrees C dry and 75 degrees C wet temperature ratings per THHN specification
• PVC insulation with nylon jacket for abrasion resistance in conduit pulls
• Black insulation color for hot-leg identification in single-phase wiring
• 500-foot spool — reduces mid-run splices on full circuit pulls

Compatibility

Designed for use in conduit systems where THHN or THWN-rated conductors are required by code. Suitable for installation in EMT, rigid metal conduit, PVC conduit, and similar raceway systems per NEC guidelines for 14 AWG branch circuit applications.

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 pulling or terminating conductors. Use appropriate wire-pulling lubricant for long conduit runs to prevent insulation damage. Solid conductors are not recommended for applications requiring repeated flexing or vibration resistance.
