  • 100 ft continuous length covers full harness runs without splices
  • Black PVC insulation identifies ground or accessory circuits clearly

12 AWG Primary Wire 100 ft

Southwire 12 AWG automotive primary wire is a single-conductor cable built for low-voltage vehicle circuits. The stranded copper core provides flexibility for routing through tight chassis spaces. Black PVC insulation resists abrasion and common automotive fluids. Supplied in a 100 ft spool for extended wiring jobs.

Suits 12 V vehicle rewiring not high voltage

This wire suits technicians rewiring lighting, accessory feeds or sensor circuits on 12 V systems. The 60 V rating covers standard automotive voltages with margin. Builders needing shielded cable, multi-conductor looms or higher temperature ratings should look at specialist harness products instead.

60 V rating defines safe circuit voltage

The 60 V maximum voltage marking is the single figure that decides if this wire matches the circuit. Circuits operating above 60 V require insulation rated for that higher potential. Always verify the system voltage before installing this GPT-designated primary wire.

Questions about this item

Will the 12 AWG stranded copper conductor work with existing 12 AWG terminals in my vehicle?

Yes, the 12 AWG stranded copper conductor matches standard 12 AWG terminal sizes used in automotive wiring.

How can I verify the 60 V PVC insulation is intact after routing the 100 ft roll?

Inspect the black PVC jacket along the full length for cuts or abrasion, then perform a continuity test on the single copper conductor.

Does the 100 ft spool of GPT primary wire include any connectors or terminals?

No, the box contains only the 100 ft roll of 12 AWG black PVC-insulated copper wire; terminals and connectors are sold separately.
