The SOUTHWIRE 11587358 is a 500-foot roll of 12 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 electrical installations. The conductor is solid copper with flame-retardant PVC insulation and a nylon outer jacket. The nylon jacket adds mechanical protection and makes the wire easier to pull through conduit. This wire is UL listed and suited for electricians working on branch circuit wiring, panel feeds, and fixture connections.
This wire is intended for use in conduit and raceways as required by NEC guidelines for building wire installations. The 12 AWG solid conductor is commonly used in residential branch circuits, lighting runs, and light commercial control wiring. The black jacket color follows standard color-coding conventions for ungrounded conductors in single-phase and three-phase systems.
Designed for use in conduit and raceway systems as general-purpose THHN building wire for power, lighting, and control circuits in residential and commercial construction.
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 terminations. THHN wire must be installed in conduit or a listed raceway — it is not rated for direct burial or open-air wiring applications. Use appropriate wire pulling lubricant and conduit fill calculations when routing through conduit runs.
