Southwire 55678923 Automotive Primary Wire 12 Gauge 100 Ft

Product Description

The SOUTHWIRE 55678923 is a 12-gauge automotive primary wire rated for surface vehicle electrical systems. Supplied on a 100-foot spool, it features a green PVC outer jacket with an outside diameter of 0.145 inches and a 19/25 strand configuration for flexibility during routing. The wire is rated at 60 volts and up to 85 degrees F for maximum operating temperature. It is a standard choice for licensed auto electricians, marine technicians, and fleet maintenance professionals who need reliable low-voltage wiring for vehicle accessory circuits, chassis wiring, and power distribution runs.

This primary wire is intended for use in surface vehicle electrical systems where color-coded wiring is required for circuit identification. The green jacket aids in quick visual tracing during installation and diagnostics. At 100 feet per spool, it covers typical full-vehicle accessory wiring jobs or multiple shorter runs without the need to splice. It is well suited for custom automotive builds, trailer wiring, and general vehicle electrical repair work.

Installation Notes

Installation should be performed by a qualified auto electrician or technician familiar with vehicle wiring practices. Disconnect the vehicle battery before beginning any wiring work to prevent shorts or arc faults. Route and secure wire away from heat sources, sharp edges, and moving components, using appropriate grommets and loom where the wire passes through panels or firewalls. Follow applicable vehicle manufacturer wiring standards and local codes when integrating into chassis electrical systems.
