Application Notes

This marine-grade primary wire is ideal for point-to-point wiring, internal control panels, and low-voltage systems in boats, trailers, RVs, and off-road equipment. The tinned copper conductor resists corrosion in harsh environments, while the PVC jacket provides protection against abrasion and chemical exposure. Color options support quick circuit identification and troubleshooting in OEM and aftermarket setups.
