The SOUTHWIRE 11580858 is a 500-foot roll of 14 AWG solid copper THHN building wire with a white jacket, rated for use in commercial and residential electrical installations. This wire carries a 600-volt rating and is insulated with flame-retardant PVC with an outer nylon jacket, meeting the temperature rating of 90 degrees C in dry and damp locations. It is designed for power distribution, lighting circuits, and control wiring routed through conduit or raceway systems. Licensed electricians and electrical contractors install this wire during rough-in and finish electrical work on both new construction and retrofit projects.
This wire is suited for general-purpose branch circuit wiring in residential, commercial, and light industrial buildings. Its solid conductor construction makes it well-matched for conduit runs where wire pulling and termination at devices, panels, and junction boxes require consistent gauge geometry. The 500-foot roll length supports full-circuit runs without mid-run splices in most standard applications. The white jacket color identifies the conductor as a neutral in standard NEC color-coding practice, though local code authority should always be consulted for jurisdiction-specific requirements.
Designed for use in conduit and raceway systems as general-purpose THHN building wire for power, lighting, and control wiring circuits in residential, commercial, and light industrial construction.
Installation should 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 or panel before pulling or terminating wire. THHN wire must be installed within a conduit or raceway — it is not rated for direct burial or exposed use without a listed conduit system. Avoid kinking or sharp bends during pulling to maintain insulation integrity.
