SOUTHWIRE COMPANY

SOUTHWIRE COMPANY 22955901 THHN 14 AWG 500 ft Black Nylon Jacket

SKU CH-BFR9-5RKFE

Single-conductor 14 AWG THHN wire with 19-strand copper, PVC insulation and nylon jacket on a 500 ft spool rated 600 V

  • TypeWire & Cable
  • THHN 600 V rating meets common branch-circuit needs
  • 14 AWG stranded copper with 19 strands bends easily in conduit
  • 500 ft spool reduces mid-job splices on large runs
  • PVC insulation plus nylon jacket resists abrasion and moisture
  • Black jacket identifies phase conductors at a glance

14 AWG THHN building wire for 600 V circuits

This 500-foot spool of single-conductor THHN wire is rated for 600 V AC and suited to conduit or raceway installations in residential and light-commercial projects. The stranded copper core uses 19 strands for flexibility during pulling and termination.

PVC insulation with nylon jacket resists heat

The PVC insulation is covered by a 0.11-inch nylon jacket that protects against oil, gasoline and mechanical damage while meeting the THHN temperature rating. The construction keeps the cable diameter small for easier conduit fill.

Black colour coding simplifies phase identification

The black jacket provides clear phase identification in multi-wire runs, reducing wiring errors during installation. Supplied on a spool, the 500-foot length allows continuous pulls without splices in typical branch-circuit work.

Questions about this item

How do I install 14 AWG THHN wire in conduit and what step is often missed?

Strip the PVC insulation and nylon jacket carefully to avoid nicking the 19-strand conductor, then pull the 500 ft spool through conduit without exceeding the 0.11 in outside diameter fill limit.

What maintenance or replacement will this THHN wire need over time?

Inspect the black nylon jacket periodically for cracks, abrasion, or chemical damage; replace any section where the PVC insulation or nylon jacket is compromised.

What limit appears first when this wire runs continuously at full load?

The 600 V AC insulation rating sets the voltage ceiling; sustained current must stay within the ampacity allowed for 14 AWG conductors in the specific installation environment.
