Our take on the Southwire Building Wire THHN 8 AWG 500 ft

Southwire THHN 8 AWG is a 500 ft spool of single-conductor building wire with a yellow nylon jacket over PVC insulation. It is rated 600V AC and built for conduit runs in branch circuits, feeders and subpanels. The 19-strand copper conductor bends more easily than solid 8 AWG, which helps in tight conduit and panel work. It is a practical pick for feeders and larger branch circuits where 8 AWG is required; rivals differ mainly in strand count, jacket color and spool length.

Pros
  • 19-strand conductor pulls and bends more easily than solid wire
  • THHN nylon jacket slides through conduit
  • 600V AC rating covers most residential and light commercial work
  • 500 ft spool suits longer runs with less splicing
  • Yellow jacket makes the 8 AWG run easy to trace
Cons
  • Single conductor: no ground wire included
  • Not rated for direct burial without conduit
  • Stranded wire needs care when terminating in lugs
  • One color only, so circuits can't be color-coded by wire

Questions and answers

Is this wire solid or stranded?
It is stranded: 19 strands make up the 8 AWG conductor. That makes it more flexible than solid 8 AWG for pulling through bends.
Can I run this outdoors or underground?
THHN is a conduit wire. It is not rated for direct burial; run it inside conduit for outdoor or underground work.
Does the spool include a ground wire?
No. It is a single conductor, so a separate ground wire is needed for most circuits.
What voltage is it rated for?
600V AC, which covers standard residential and light commercial circuits.
How big is the wire?
The nominal outside diameter is about 0.21 in., which matters when sizing conduit fill.
Where is the Southwire Building Wire THHN 8 AWG 500 ft cheapest?
At Newegg, for $455.99, as of our latest check.
