Thhncu-generic thhn10solblk2500r Thhn 10 Awg Solid Wire 2500 Ft

Product Description

The THHNCU-GENERIC thhn10solblk2500r is a 10 AWG solid plain copper THHN building wire rated at 600 volts, supplied on a 2500-foot reel. The conductor is solid-stranded copper with PVC insulation and a nylon jacket in black, giving it the dual THHN/THWN-2 profile common to this construction. Temperature ratings are 90 degrees C in dry locations and 75 degrees C in wet locations. Ampacity is 30 amps at 90 degrees C, making it a standard choice for 20-amp and 30-amp branch circuit wiring in residential and light commercial work. Electricians pull this wire through conduit for general-purpose wiring applications governed by the NEC.

This wire is used in residential and light commercial electrical installations wherever code requires conductors in conduit. Typical applications include branch circuits, feeder runs, panel feeders, and general-purpose outlet and lighting circuits. The black insulation color is the standard designation for ungrounded hot conductors in single-phase and three-phase systems. The 2500-foot reel quantity suits service contractors, electrical contractors, and wholesale buyers stocking wire for multiple jobs.

Key Features

• 10 AWG solid plain copper conductor for reliable conductivity and straightforward termination
• 600-volt rating suitable for standard branch circuit and feeder applications
• 30-amp ampacity at 90 degrees C dry; 20-amp ampacity at 75 degrees C wet
• PVC insulation with nylon jacket for smooth conduit pull and abrasion resistance
• Black insulation color identifies ungrounded hot conductors per NEC color conventions
• 2500-foot reel reduces splicing and is sized for large-volume job-site use

Compatibility

Designed for installation in conduit systems including EMT, rigid metal conduit, PVC conduit, and other raceway types where THHN-rated conductors are specified per NEC Article 310 and applicable local codes.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and applicable local electrical codes. De-energize and lock out the circuit or panel before making any connections. Pull wire through conduit using appropriate wire-pulling lubricant to avoid jacket damage; do not kink or crush the conductor. Verify that conduit fill does not exceed NEC Chapter 9 limits for the conduit type and size being used.
