Building wire for 600 V circuits

Southwire Company THHN 12 AWG solid conductor is rated for 600 V AC and comes on a 100 ft spool. The PVC insulation and nylon jacket are coloured white for easy identification in conduit runs. It is intended for electricians and installers pulling individual conductors through raceway.

Replaces damaged or undersized single conductors

When existing 12 AWG THHN has degraded insulation or a circuit needs a fresh home run, this spool provides a direct, code-compliant replacement. The solid conductor simplifies termination on screw terminals and the 0.12 in outside diameter fits standard conduit fill tables. The jump is worth it when the old wire shows cracking or when a new branch circuit is added.

Performs steadily in conduit under continuous load

The nylon jacket resists abrasion during long pulls and the PVC insulation maintains its dielectric strength at the rated voltage. Heat dissipates through the conduit walls during sustained operation, and the solid conductor avoids strand fatigue at connection points. The spool format keeps the wire straight for faster installation.

Questions about this item

What conduit size fits the 0.12 in outside diameter of this 12 AWG THHN wire?

A 1/2 in electrical conduit provides enough fill capacity for the 0.12 in nominal outside diameter of this solid conductor.

How is this solid 12 AWG THHN wire pulled through conduit without damaging the nylon jacket?

Apply pulling lubricant to the nylon jacket and feed the wire steadily from the spool to prevent kinking the solid conductor.

When should this 12 AWG THHN wire be replaced after installation in conduit?

Replace the wire if the PVC insulation or nylon jacket shows cracking, discolouration, or heat damage during periodic inspections.
