Southwire 22959101 Thhn Thwn 14 Awg Building Wire 500 Ft

Product Description

The SOUTHWIRE 22959101 is a 14 AWG stranded copper building wire rated for THHN and THWN applications, supplied in a 500-foot spool. The conductor consists of 19 strands of copper encased in thermoplastic insulation with a nylon jacket, yielding a flexible, durable wire suited for pulling through conduit in commercial and residential wiring systems. The green jacket identifies this as a grounding conductor per NEC color-coding conventions. Rated at 600 volts and 15 amps, this wire meets the demands of branch circuit and equipment grounding installations handled by licensed electricians.

This wire is used in conduit runs for branch circuits, panel feeders, and equipment grounding in both residential and light commercial construction. The stranded core makes it easier to route through conduit bends compared to solid wire. The THWN rating adds moisture resistance for wet or damp location conduit runs, while the THHN rating suits dry location installations. Green-jacketed wire is the standard choice for equipment grounding conductors in NEC-compliant electrical systems.

Key Features

• Stranded copper conductor — 19 strands, 14 AWG — for flexibility during conduit pulls
• Dual THHN/THWN rating covers dry, damp, and wet conduit locations
• 600-volt rating suitable for standard branch circuit and grounding applications
• Maximum operating temperature of 194 degrees F
• Nylon outer jacket resists abrasion, gasoline, heat, moisture, and oil
• Green jacket color designates use as an equipment grounding conductor per NEC requirements
• 500-foot spool reduces splices on longer runs

Compatibility

Designed for use in conduit-based wiring systems requiring THHN or THWN-rated conductors at 14 AWG, including equipment grounding conductor applications in NEC-compliant residential and commercial electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify zero voltage with a meter before making any connections. Green-jacketed wire is reserved for equipment grounding conductors — do not use it as an ungrounded (hot) or grounded (neutral) conductor. Use appropriate wire-pulling lubricant when routing through long or multi-bend conduit runs to avoid jacket damage.
