SOUTHWIRE COMPANY 11594901 THHN Wire 12 AWG Brown Solid 500 ft

SKU CH-C40C-36M5S

THHN building wire, 12 AWG solid copper, brown PVC insulation with nylon jacket, 600 V, 500 ft on a spool

  • Length5.400
  • TypeWire & Cable
  • 12 AWG solid copper handles 600 V AC loads
  • 500 ft spool covers long residential runs
  • Brown jacket identifies circuit at a glance
  • PVC insulation with nylon jacket resists abrasion
  • 12 in diameter fits standard conduit

Application fit

This 12 AWG solid THHN building wire suits electricians and installers running branch circuits in conduit or raceway. The brown jacket identifies phase conductors in standard colour codes. It is not for buyers who need stranded conductors for frequent flexing or direct-burial ratings.

Sustained load behaviour

Rated for 600V AC with PVC insulation and a nylon jacket, the conductor resists heat and abrasion during continuous service. The 0.12 in nominal outside diameter maintains consistent fill ratios in conduit. It is not for users who require higher temperature ratings or armoured protection.

Build quality and connectors

Solid copper construction provides stable terminations under screw terminals without strand breakage. Supplied on a 500 ft spool for straight pulls and easy storage. It is not for projects needing pre-cut lengths, colour variety packs or connectors included.

Questions about this item

How much heat does the 12 AWG solid copper conductor generate when carrying full load all day?

The 12 AWG solid copper conductor is rated for 600V AC operation with PVC insulation and a nylon jacket, designed to handle continuous loads within NEC ampacity limits for this wire size.

What connectors or terminals are required to terminate the solid 12 AWG conductor properly?

Use UL-listed connectors rated for solid 12 AWG copper wire, such as screw terminals, push-in connectors rated for solid conductors, or wire nuts sized for 12 AWG solid copper.

Can this brown 12 AWG THHN wire be pulled through existing conduit that already contains older insulation types?

Yes, the 0.12 in nominal outside diameter with smooth nylon jacket allows pulling through conduit with existing wires, provided fill calculations and insulation compatibility follow NEC guidelines.
