Southwire 11588158 Thhn Building Wire 12 Awg Solid 500 Ft

Product Description

The SOUTHWIRE 11588158 is a 500-foot roll of 12 AWG solid white THHN building wire rated for general-purpose power, lighting, and control wiring in residential and commercial installations. The conductor is solid copper with flame-retardant PVC insulation and a nylon jacket, giving it a small diameter that threads easily through conduit. The wire carries a 600-volt rating and is rated to 90 degrees C, making it suitable for a wide range of branch-circuit and feeder applications. Licensed electricians and electrical contractors are the primary installers of this wire type.

This wire is designed for use in conduit and raceways as required by NEC installation methods. Typical applications include branch circuits, lighting circuits, and control wiring in residential, commercial, and light industrial buildings. The solid conductor format is well suited to device terminations and shorter conduit runs where flexibility is less critical than a clean, solid connection at terminals and receptacles.

Key Features

• 12 AWG solid copper conductor for reliable conductivity and firm terminal connections
• 600-volt rated insulation suitable for standard branch-circuit and feeder wiring
• 90 degrees C temperature rating for use in higher-ambient environments
• Flame-retardant PVC insulation with nylon jacket for added mechanical protection
• Resistant to oil, gasoline, chemicals, and abrasion
• UL listed for code-compliant installations

Compatibility

Designed for installation in conduit and raceways per NEC requirements, suitable for standard 12 AWG branch-circuit applications in residential, commercial, and light industrial wiring systems.

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 before making any connections. Pull wire through conduit or raceway using appropriate wire-pulling lubricant to avoid jacket damage. Solid conductors should be terminated with listed connectors rated for solid wire.
