Southwire 18 AWG Automotive Primary Wire

This 100 ft spool of Southwire 55835023 is a single-conductor GPT wire rated for 60 V. It uses fully annealed copper strands with dark green PVC insulation. The wire is designed for low-voltage automotive circuits and general-purpose electrical work.

Suits low-voltage automotive wiring and repair jobs

Builders who need higher voltage ratings, multiple conductors or larger gauge sizes should look elsewhere. The 18 AWG cross-section limits current capacity, so it is not for starter cables or heavy accessory feeds. Buyers needing shielded or jacketed cable for data or audio signals will also need a different product.

Simple to cut, strip and route in tight spaces

The stranded copper conductor bends easily around corners and through loom without spring-back. PVC insulation strips cleanly with standard hand tools and resists abrasion and automotive fluids. Common issues include nicking strands if dull cutters are used and ensuring crimp terminals match 18 AWG to avoid loose connections.

Questions about this item

What connectors or terminals does this 18 AWG stranded copper wire need for a secure crimp?

Use terminals rated for 18 AWG stranded copper; the fully annealed conductor crimps cleanly with standard automotive open-barrel or closed-barrel terminals matched to that gauge.

Can this 60 V GPT wire run in the same harness as existing lower-voltage circuits in the vehicle?

Yes, the 60 V rating and PVC insulation allow it to share a loom with typical low-voltage automotive circuits provided each wire’s insulation remains intact.

How can I confirm the 100 ft spool delivers continuous 18 AWG conductor without splices?

Inspect the full length; the single-conductor GPT design uses a uniform dark-green PVC jacket over stranded fully annealed copper with no factory splices.
