Thhncu-generic thhn14strblk2500r Thhn 14AWG Copper Wire 2500ft

Product Description

The THHNCU-GENERIC thhn14strblk2500r is a 14 AWG stranded copper THHN building wire supplied on a 2500-foot reel with black PVC insulation and a nylon jacket. Rated at 600 volts, this wire is suitable for use in conduit runs in branch circuits, panels, and general wiring applications. The 19-strand configuration provides flexibility during pull-through in conduit. With a temperature rating of 90 degrees C in dry locations and 75 degrees C in wet locations, it meets the thermal demands of standard residential and light commercial electrical installations. Licensed electricians and electrical contractors are the primary installers of this wire type.

This wire is used in residential and commercial electrical systems for branch circuit wiring, feeder runs, and equipment connections where installation inside conduit or cable trays is required. The black insulation color is standard for use as a hot conductor in single-phase and three-phase systems. The 2500-foot reel format is suited for larger projects or supply-house stocking where pull quantities vary by job.

Key Features

• 14 AWG stranded copper conductor with 19-strand configuration for pull flexibility
• 600-volt rating suitable for standard branch circuit and feeder applications
• 90 degrees C dry / 75 degrees C wet temperature rating
• PVC insulation with nylon jacket for abrasion resistance in conduit pulls
• Black insulation color for hot-conductor identification per NEC convention
• 2500-foot reel format reduces waste and suits larger job pulls

Compatibility

Designed for use in conduit, raceways, and cable trays as an OEM-style THHN building wire for standard residential and commercial electrical branch circuit and feeder wiring 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 terminating or splicing conductors. THHN wire must be installed inside an approved raceway, conduit, or cable tray — it is not rated for direct burial or exposed outdoor use without additional protection. Verify conductor ampacity derating requirements when bundling multiple current-carrying conductors in the same conduit.
