Southwire 55671423 12 Awg Automotive Primary Wire 100 Ft

Product Description

The SOUTHWIRE 55671423 is a 12 AWG automotive primary wire designed for surface vehicle electrical systems. It ships as a 100-foot spool with white PVC outer insulation, making it straightforward to identify in multi-circuit wiring harnesses and panel runs. Rated at 60 volts and a maximum temperature of 85 degrees C, this wire is suited for low-voltage DC circuits found in cars, trucks, trailers, and specialty vehicles. The 19/25 strand construction provides flexibility during routing through tight passages, bulkheads, and conduit. Electricians and automotive technicians reach for this wire when building or repairing primary power and accessory circuits in mobile applications.

This wire is built for use in surface vehicle electrical systems, covering automotive, light truck, trailer, and marine accessory wiring applications. The white color coding supports organized, readable harness work where circuit identification is critical. The 100-foot spool length is practical for shop stock or vehicle-level projects requiring extended runs, such as auxiliary lighting, accessory power, or relay circuits. It is appropriate for both new harness construction and repair work on existing vehicle wiring.

Key Features

• 12 AWG conductor sized for moderate-current automotive circuits
• 100-foot spool for extended runs or shop inventory
• White PVC insulation for color-coded circuit identification
• 19/25 stranded construction for flexibility in tight routing paths
• 60-volt rating suitable for standard 12-volt and 24-volt DC vehicle systems
• Rated to 85 degrees C for use in under-hood and high-temperature environments

Compatibility

Designed for use in surface vehicle electrical systems as a general-purpose automotive primary wire; suitable for 12-volt and 24-volt DC accessory, power distribution, and relay circuits in automotive and light-duty vehicle applications.

Installation Notes

Installation should be performed by a qualified electrician or experienced automotive technician following applicable vehicle wiring standards. Disconnect the battery before beginning any wiring work to eliminate shock and short-circuit risk. Use proper crimp connectors, heat-shrink terminals, or solder-and-shrink joints rated for the circuit load; avoid using wire nuts in mobile or vibration-prone applications. Route and secure wire away from heat sources, sharp edges, and moving components to prevent insulation damage.
