Whether you're wiring up new 12-volt accessories, running a lighting circuit, or repairing a chafed run, this East Penn primary wire is a shop staple. The 12-gauge stranded copper conductor carries current reliably for typical RV and automotive loads.
The 100-foot spool gives you plenty to work with, and the red insulation color-codes the run so you can keep positive and circuit assignments clear. It's flexible single-conductor wire that's easy to route through the tight spaces behind panels and under the rig.
Keep a spool on hand and you're ready for the next accessory install or wiring repair.
