10/3 Triplex Marine Cable, Tinned Copper, UL 1426

This 10/3 triplex marine cable bundles three 10 AWG tinned-copper conductors into a single flat jacket — the standard choice for DC wiring runs on boats, RVs, trucks, and trailers where corrosion resistance and flexibility matter. Tinned copper strands resist salt air and moisture far better than bare copper, and the flat triplex profile makes it easy to route through tight bulkheads and conduit.
