Buying Guide

Choose the right AWG for the circuit

Match wire gauge to circuit amperage and run length — 12 AWG for higher-current circuits, 14–16 AWG for lighting and accessories — to minimize voltage drop and heat

Prefer tinned copper conductors

Tinned copper resists corrosion in marine environments better than bare copper, improving longevity on saltwater boats

Check strand count and flexibility

Higher strand count makes cable more flexible and easier to route in tight spaces common on boats

Select appropriate insulation and jacket

Look for marine-rated insulation that resists oil, fuel, UV and abrasion to withstand the boat environment

Buy the needed length and configuration

Choose between duplex cable for paired runs and single-conductor spools; account for extra length to allow for routing and terminations
