Southwire 11580858 14 Awg Solid Thhn Wire 500 Ft White

Product Description

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.

Key Features

• 14 AWG solid copper conductor for reliable conductivity and consistent terminations
• 600-volt rating for standard branch circuit and control wiring applications
• 90 degrees C temperature rating suitable for dry and damp location conduit runs
• Flame-retardant PVC insulation with nylon outer jacket for mechanical protection
• Resistant to oil, gasoline, chemicals, and abrasion for demanding conduit environments
• UL listed for code-compliant installations

Compatibility

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 Notes

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.
