Marine Wire

Marine Wire built to ABYC E-11 and UL 1426 uses tinned copper conductors and oil-resistant insulation that hold up to salt air, vibration, and engine-bay heat. Bare copper corrodes fast in marine conditions, which is why marine electrical wire spec sheets call out tinned strands. The right gauge depends on circuit load, run length, and acceptable voltage drop.

DK Hardware stocks marine wire and cable for new builds, repower projects, and electrical refits:

AWG range: 18 AWG primary up to 4/0 cable for marine batteries and high-load runs
Primary tinned copper, flat duplex, and triplex cable
Color-coded insulation per the ABYC marine wire color code
Heat shrink butt connectors, ring terminals, and adhesive-lined marine wire connectors
Brands including Ancor, the dominant US marine wire brand

Pair the wire with electrical distribution components like fuse blocks, breakers, and busbars to meet ABYC overcurrent protection requirements.
