Southwire 55671723 12 Awg Automotive Primary Wire 100 Ft

Product Description

The SOUTHWIRE 55671723 is a 12 AWG automotive primary wire designed for use in surface vehicle electrical systems. This 100-foot spool delivers reliable current-carrying capacity in low-voltage DC circuits rated at 60 volts. The yellow PVC outer insulation provides color-coded circuit identification and resists abrasion, moisture, and heat up to 85 degrees F. The 19/25 stranded conductor construction offers flexibility during routing through tight chassis runs, firewall grommets, and body panels. Licensed automotive electricians, fleet technicians, and 12-volt installers rely on this wire for a wide range of vehicle wiring applications.

This wire is suited for surface vehicle electrical systems including passenger vehicles, light trucks, trailers, marine applications, and heavy equipment auxiliary circuits. The 100-foot spool length accommodates multi-run installations without splicing, making it practical for full harness builds or large repair jobs. The yellow color coding simplifies circuit tracing during diagnostics and meets common color-coding conventions for secondary and accessory circuits. It arrives on a spool package for organized dispensing on the job or at the bench.

Key Features

• 12 AWG stranded conductor with 19/25 strand count for flexibility in tight routing
• 60-volt DC rating suitable for standard surface vehicle electrical systems
• PVC outer insulation rated to 85 degrees F for under-hood and chassis environments
• Yellow color coding for circuit identification and tracing
• 100-foot spool package reduces splicing on larger installs
• 0.145 inch outside diameter for compatibility with standard automotive terminals and grommets

Compatibility

Designed for use in surface vehicle electrical systems including automotive, light truck, trailer, and equipment auxiliary wiring where 12 AWG primary wire at 60 volts DC is specified.

Installation Notes

Installation should be performed by a qualified automotive or 12-volt electrician following applicable vehicle wiring standards. Disconnect the vehicle battery before beginning any wiring work to prevent shorts and arc damage. Use appropriately rated crimp terminals, connectors, and inline fuse holders sized for 12 AWG conductors. Route wire away from sharp edges, exhaust components, and moving parts, and secure with appropriate loom or grommets where passing through body panels.
