Southwire 55672123 Automotive Primary Wire 10 Awg 100 Ft Red

Product Description

The SOUTHWIRE 55672123 is a 10-gauge automotive primary wire rated for use in surface vehicle electrical systems. This 100-foot spool delivers a stranded copper conductor with 19/23 strand count, housed in a red PVC outer insulation. The wire is rated at 60 volts and handles continuous use up to 85 degrees F. The red color coding supports organized, readable wiring layouts in automotive and marine environments. Licensed electricians, auto electricians, and experienced technicians use this wire for power distribution, accessory wiring, and circuit extensions in vehicle builds and retrofits.

This wire is suited for 12-volt and low-voltage DC electrical systems found in cars, trucks, trailers, RVs, and other surface vehicles. The 100-foot length accommodates full vehicle runs or multiple shorter circuit segments from a single spool. The 10-gauge rating makes it appropriate for moderate-current applications such as lighting circuits, auxiliary power feeds, and relay-controlled loads where conductor sizing must align with fuse and load requirements.

Key Features

• 10 AWG stranded conductor with 19/23 strand count for flexibility during routing
• PVC outer insulation rated to 85 degrees F for engine-compartment-adjacent applications
• 60-volt rating suitable for standard automotive DC electrical systems
• Red color coding for consistent circuit identification and polarity marking
• 100-foot spool provides sufficient length for full vehicle wiring runs
• Outside diameter of 0.178 inches for routing through grommets and conduit

Compatibility

Designed for use in surface vehicle electrical systems, including automotive, truck, trailer, and RV wiring applications requiring 10 AWG primary wire.

Installation Notes

Installation should be performed by a qualified auto electrician or experienced technician familiar with low-voltage DC wiring practices. Disconnect the vehicle battery before beginning any wiring work to eliminate arc and short-circuit risk. Route wire away from sharp edges, exhaust components, and moving parts, using grommets where passing through metal panels. Size fuses and circuit protection to match the wire gauge and load requirements per applicable vehicle wiring standards.
