Southwire Company Llc 55671333 Primary Wire 12 Gauge

Product Description

The SOUTHWIRE COMPANY LLC 55671333 is a 12-gauge primary wire in black, sold in an 11-foot length. Primary wire is a single-conductor, insulated wire used for low-voltage DC circuit wiring in automotive, marine, RV, and general electrical applications. At 12 gauge, it carries sufficient current capacity for accessory circuits, lighting runs, and control wiring. Electricians, automotive technicians, and marine service pros use this wire when routing circuits from a power source to a load such as a relay, switch, or accessory component. The black insulation color is standard for ground or negative conductors in 12-volt DC systems.

This wire is suited for low-voltage wiring tasks in light-duty electrical installations. Common applications include vehicle accessory wiring, trailer lighting circuits, small engine control leads, and panel-to-component runs in equipment bays. At 11 feet per card, it provides enough length for most single-run accessory or control circuit installations without requiring a full spool. It is packaged individually on a card, with a package quantity of 6 cards per case.

Key Features

• 12-gauge conductor provides solid current capacity for accessory and control circuits
• 11-foot length suits single-run wiring tasks without excess waste
• Black insulation for standard negative or ground identification in DC systems
• Single-conductor primary wire design for flexible routing in tight spaces
• Carded packaging for easy retail or shop-stock handling

Compatibility

Designed as a general-purpose primary wire suitable for low-voltage DC wiring applications in automotive, marine, RV, and light-duty equipment electrical systems.

Installation Notes

Installation should be performed by a qualified electrician or automotive technician familiar with low-voltage DC wiring practices. Disconnect the battery or power source before making any connections to prevent short circuits or accidental current flow. Use the appropriate wire terminals, connectors, and heat-shrink or electrical tape to secure and protect all termination points. Follow applicable wiring codes and manufacturer guidelines for circuit protection, including correct fuse sizing for the load being served.
