Beginner’s Guide to Marine Electrical Systems

Most boats rely on a 12V DC system powered by one or more marine batteries. This system runs essentials like pumps, radios, and lights. Larger vessels may also include 120V AC shore power for appliances when docked. Unlike automotive wiring, marine electrical systems are built to resist saltwater, vibration, and constant load — making the right components critical for safety and performance.
