SKU CH-VWP1-VB7EC

THHN 8 AWG stranded copper wire with PVC insulation and a nylon jacket, 500 ft on a spool, rated 600 V AC

  • TypeWire & Cable
  • THHN 600 V rating meets commercial wiring codes
  • Stranded 19-conductor design eases pulling through conduit
  • 500 ft continuous spool reduces splice points
  • Nylon jacket over PVC resists abrasion and chemicals
  • Yellow colour coding simplifies circuit identification

8 AWG THHN building wire for conduit runs

This single-conductor wire carries a 600V AC rating and uses stranded copper with PVC insulation and a nylon jacket. The yellow colour identifies the phase in standard wiring schemes. It is supplied on a 500 ft spool for continuous pulls in commercial and residential conduit systems.

Replaces solid or smaller-gauge hookup wire

The 19-strand construction bends more easily than solid 8 AWG when routing through bends and junction boxes. The nylon jacket resists abrasion while pulling through EMT or PVC conduit. The upgrade is worth it when voltage drop calculations demand 8 AWG and the installation requires flexible stranded conductors.

Spooled for straight pulls into conduit

Cut the required length, strip the PVC insulation, and terminate under lugs or connectors rated for 8 AWG. The .21 in outside diameter fits standard 8 AWG ferrules and set-screw connectors. Common issues include nicking strands while stripping and over-tightening terminals, which can cut the fine strands.

Questions about this item

What conduit size fits the 0.21 in outside diameter of this 8 AWG THHN wire?

The nominal outside diameter is 0.21 in. Choose conduit fill tables for 8 AWG stranded conductors to meet NEC fill limits.

How do I strip the PVC insulation without damaging the 19-strand conductor?

Use a calibrated stripper for 8 AWG stranded wire. Cut the nylon jacket first, then strip the PVC cleanly to avoid nicking the 19 individual strands.

When should I replace this yellow THHN wire if the nylon jacket shows cracks?

Replace the wire if the nylon jacket is cracked, brittle, or discoloured, as this exposes the PVC insulation to moisture and physical damage.
