THHN 14 AWG Solid Conductor Wire

This 100-foot spool provides a single solid conductor insulated with PVC and rated for 600 volts. The nominal outside diameter is 0.1 inch. It is supplied new on a spool for easy handling during installation. The black insulation identifies the conductor in conduit or raceway systems.

Capacity and Headroom for 14 AWG Circuits

The 14 AWG solid copper conductor suits branch circuits protected at 15 amperes. It handles lighting loads and general-purpose receptacles within that limit. Voltage drop becomes a concern on runs approaching the full 100 feet under continuous load. The insulation is rated 600 volts, so it is not suitable for higher voltage distribution.

THHN Insulation and Conduit Use Limits

THHN insulation is thermoplastic nylon rated for dry and damp locations at 90 degrees Celsius. It must be installed inside approved conduit or tubing; it is not rated for direct burial or exposed use. The single conductor requires a complete raceway system between boxes. Local codes govern maximum fill and ampacity adjustments for the conduit size used.

Questions about this item

Will the 14 AWG solid THHN wire pull smoothly through existing conduit that already contains older wiring?

The 0.1 in outside diameter and solid conductor help it slide through crowded conduit without snagging on existing cables.

How can I verify the 600 V insulation is intact after pulling the 100 ft spool through the run?

Inspect the black PVC jacket for cuts or abrasion and run a continuity test on the single solid conductor from end to end.

Does the 100 ft spool include any connectors or staples, or must they be purchased separately?

The package contains only the 14 AWG THHN wire on a spool; connectors, staples and conduit fittings are sold separately.
