  • Length1.070
  • TypeStranded
  • White insulation for quick circuit identification
  • THHN 8 AWG stranded copper rated 600 V
  • 19-strand construction gives flexibility in conduit
  • 100 ft coil covers long residential runs
  • Nominal 0.21 in diameter fits standard raceways

Product Identity

This is a 100-foot coil of 8 AWG stranded THHN building wire in white. It is intended for electricians and installers pulling conductors through conduit for 600-volt circuits in residential or commercial projects.

Critical Specification

The conductor uses 19-strand construction with PVC insulation and a nominal outside diameter of .21 inches. This stranding and diameter determine whether the wire fits your conduit fill calculations and terminates cleanly on the devices you are using.

Sustained Load Behavior

Rated for 600 volts, the PVC insulation maintains its dielectric strength during continuous operation at the ampacity allowed for 8 AWG in your installation environment. The stranded design resists work hardening when the run is pulled through bends, preserving conductor integrity over the full 100-foot length.

  • THHN 8 AWG stranded copper rated 600 V
  • 19-strand construction gives flexibility in conduit
  • 100 ft coil covers long residential runs

Questions about this item

What does the 8 AWG stranded construction mean for current-carrying capacity in a real installation?

The 19-strand 8 AWG conductor is rated for 600 V and fits standard ampacity tables for THHN wire in conduit or raceway.

How does the THHN designation limit the voltage and environment where this wire can be used?

THHN insulation is PVC with a nylon jacket, rated 600 V for dry or damp locations; it is not rated for direct burial or wet locations without additional protection.

What conduit size and bend radius does the 0.21 in outside diameter require?

At 0.21 in nominal OD, the wire fits 1/2 in conduit with room for multiple conductors; minimum bend radius follows NEC guidelines for 8 AWG stranded THHN.
