Southwire 11579058 Thhn Wire 14 Awg Solid Black 500 Ft

Product Description

The SOUTHWIRE 11579058 is a 500-foot roll of 14 AWG solid copper THHN building wire in black. Rated for 600 volts and 90 degrees C, it is designed for general-purpose power, lighting, and control wiring in commercial and residential applications. The conductor is wrapped in flame-retardant PVC insulation with a nylon outer jacket, giving it resistance to oil, gasoline, chemicals, and abrasion. This wire is UL listed and sold as a single roll. Electricians use it in new construction, renovation, and service-change work wherever THHN is the specified wire type.

This wire is suited for installation in conduit and raceways in both residential and commercial buildings. It is a standard choice for branch circuit wiring, lighting circuits, and control runs where a solid conductor and THHN rating are required. The black jacket color assists with phase and circuit identification during installation, helping crews follow consistent color-coding practices on the job.

Key Features

• Solid copper conductor for reliable conductivity and straightforward termination
• Flame-retardant PVC insulation with nylon jacket for durability in conduit
• Rated 600 volts and 90 degrees C for broad general-purpose use
• Resistant to oil, gasoline, chemicals, and abrasion
• UL listed for code-compliant installations
• 500-foot roll reduces waste and simplifies job-site inventory

Compatibility

Designed for use in conduit and raceways as a general-purpose THHN building wire for power, lighting, and control wiring applications.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before making any connections. Use appropriate conduit-fill calculations to confirm the raceway is sized correctly for the number and gauge of conductors being pulled. Avoid sharp bends or kinks during pulling to protect the insulation and nylon jacket.
