Southwire 21124301 Thhn Thwn 14 Awg 500 Ft Solid Copper Wire

Product Description

The SOUTHWIRE 21124301 is a 14 AWG solid copper THHN/THWN building wire rated for 15 amps at 600 volts. It ships in a 500-foot spool and features thermoplastic insulation with a nylon jacket in purple. This wire is designed for use in conduit in commercial and residential electrical installations where a dual-rated THHN/THWN conductor is required. Electricians use this wire for branch circuit wiring in dry, damp, or wet locations. The purple jacket aids in circuit identification on multi-wire installations.

This 14 AWG solid wire is suited for residential and light commercial branch circuits installed in conduit or raceway systems. The THHN rating covers dry and damp locations, while the THWN rating extends use to wet locations, making it versatile across interior and exterior conduit runs. It is commonly pulled in EMT, rigid metal conduit, or PVC conduit for lighting circuits, outlet circuits, and general-purpose branch wiring where 15-amp overcurrent protection is used.

Compatibility

Designed for use in conduit or raceway systems as a general-purpose branch circuit conductor in residential and commercial electrical installations requiring a 14 AWG THHN/THWN-rated solid copper wire.

Installation Notes

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 panel before making any connections. This wire is intended for use inside conduit or approved raceway only and should not be used as a direct burial or open-air conductor. Pull tension should remain within limits appropriate for 14 AWG solid copper to avoid nicking the conductor during installation.
