Southwire 55671623 12 Awg Automotive Primary Wire 100 Ft Blue

Product Description

The SOUTHWIRE 55671623 is a 12 AWG automotive primary wire designed for surface vehicle electrical systems. It runs 100 feet per spool and features a blue PVC outer jacket rated for up to 85 degrees F and 60 volts. The 19/25 strand construction provides flexibility in routing through tight spaces, conduit, and panel runs. Licensed auto electricians and shop technicians use this wire for accessory circuits, trailer wiring, underhood harness repairs, and custom vehicle builds. The spool format makes it practical for bench work and repeated cuts on the job.

This wire is suited for 12-volt and 24-volt surface vehicle applications including light-duty trucks, trailers, boats, RVs, and automotive accessory circuits. The blue color coding supports organized, multi-conductor installations where circuit identification is important. It is appropriate for both OEM-style repair work and new circuit installation in surface vehicles. The 0.145-inch outside diameter fits standard automotive grommets and loom hardware commonly used in professional shop environments.

Installation Notes

Installation should be performed by a qualified auto electrician or experienced shop technician. Disconnect the vehicle battery before making connections to prevent short circuits or unintended current flow. Use proper automotive crimp terminals, ring connectors, or butt splices rated for 12 AWG wire. Route wire away from exhaust components and sharp metal edges, and protect runs with split loom or grommets at panel penetrations.
