Thhncu-generic thhn1/0strblkmr Thhn 1/0 Awg Black Copper Wire

Product Description

The THHNCU-GENERIC thhn1/0strblkmr is a 1/0 AWG stranded copper THHN building wire rated for 600 volts with a 90 degrees C temperature rating in both dry and wet locations. The conductor is made up of 19 strands of copper, insulated with PVC and jacketed in nylon — the standard construction for THHN/THWN-2 dual-rated wire. Ampacity is 125 amps at 60 degrees C, 150 amps at 75 degrees C, and 170 amps at 90 degrees C. This wire is sold in a 5000-foot reel and is a common choice for licensed electricians pulling feeders, branch circuits, and service entrance conductors through conduit.

This gauge and construction is used in residential, commercial, and light industrial electrical installations. Typical applications include service panel feeders, sub-panel runs, motor circuits, and large-load branch circuits where conduit-installed conductors are required by code. The 1/0 AWG size is commonly specified for 150-amp services and large HVAC equipment feeds. The black insulation color is standard for ungrounded hot conductors in multi-wire installations.

Key Features

• 1/0 AWG 19-strand copper conductor for flexibility in conduit pulls
• PVC insulation with nylon jacket — dual-rated THHN/THWN construction
• 600-volt rating suitable for standard building wiring systems
• 90 degrees C temperature rating for both dry and wet environments
• Black insulation for hot-conductor identification per NEC color conventions
• 5000-foot reel minimizes splices on large commercial or industrial jobs

Compatibility

Designed for use in conduit-based wiring systems where NEC-compliant THHN or THWN-2 building wire is specified. Suitable for use in EMT, rigid metal conduit, PVC conduit, and other raceway types per NEC Article 310 and applicable local codes.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local ordinances. Always de-energize and lock out the circuit or panel before making any connections. Use appropriately rated lugs, terminals, and conduit fill calculations per NEC Chapter 9 tables for the conduit size and wire count being installed. Do not exceed the ampacity ratings for the ambient temperature and conduit fill conditions of the specific installation.
