THHN 14 AWG Single-Conductor Wire

This 50-foot spool delivers a single 14 AWG stranded copper conductor rated for 600V AC. The PVC insulation is protected by a white nylon jacket with a nominal outside diameter of .11 inches. It is built for conduit or raceway installations in residential and commercial projects. The 19-strand construction keeps the wire flexible for easier pulling.

Replaces Solid 14 AWG or Damaged Runs

Solid-core 14 AWG wire is stiffer and harder to pull through long or bent conduit, so this stranded version saves labour on retrofit jobs. The jump is worth it when the run includes multiple bends or when the existing insulation is cracked, brittle, or colour-faded. The white jacket also provides clear circuit identification where code requires a neutral conductor.

Sustained Pulling and Thermal Performance

The nylon jacket resists abrasion during long pulls through PVC or metal conduit, reducing the risk of insulation damage. PVC insulation maintains its dielectric strength at the rated 600V AC under continuous load without softening. Stranded construction distributes mechanical stress evenly across the 19 strands, preventing conductor fatigue where the wire passes through fittings or supports.

Questions about this item

What conduit size is required for the 0.11 in outside diameter of this 14 AWG THHN wire?

Choose conduit with an inside diameter large enough to accommodate the 0.11 in nominal outside diameter while meeting NEC fill ratios for a single 14 AWG conductor.

How do you strip the PVC insulation and nylon jacket without nicking the 19-strand conductor?

Use a calibrated stripper set for 14 AWG, score the jacket gently, and pull straight off to avoid damaging the individual strands.

When should this 600V AC rated wire be replaced due to insulation degradation?

Replace if the white nylon jacket shows cracking, brittleness, or discoloration from heat, oil, or UV exposure that compromises the 600V AC rating.
