Southwire 8 AWG THHN Stranded Wire

This 500 ft spool of green Southwire building wire uses a stranded 8 AWG copper conductor with PVC insulation rated for 600 V. The THHN designation suits general purpose wiring in conduit or cable tray. It arrives on a spool for easy handling.

600 V rating and 0.21 in diameter set limits

The insulation withstands up to 600 V in dry or damp locations. At a nominal 0.21 in outside diameter, the wire fills conduit quickly, so conduit fill tables limit how many conductors share a raceway. The green colour identifies it as an equipment grounding conductor only.

19 strand construction eases pulling

The 19 strand design makes the wire more flexible than solid equivalents, helping it navigate bends during installation. Stranded conductors need proper connectors or terminals rated for stranded wire to avoid loose connections. Always verify local code requirements for grounding conductor use before starting.

Questions about this item

Is the 500 ft spool the right length for a typical residential run?

The spool contains 500 ft of 8 AWG stranded copper wire with 0.21 in outside diameter, suitable for longer branch circuits or feeder pulls.

What does the 600 V rating mean when the wire is installed in conduit?

The 600 V rating is the maximum voltage for THHN insulation; in conduit the wire can carry up to 600 V between conductors or to ground.

How does the 19-strand construction affect pulling through EMT?

Nineteen strands make the conductor flexible enough to navigate bends in EMT while keeping the 0.21 in diameter for standard fill calculations.
