Collection: Electrical

Keeping a boat's electrical system reliable means matching every component to your specific setup, from the wire gauge running to your amplifier to the inverter capacity your onboard devices actually need. Samlex pure sine wave inverters are the right choice when you're powering sensitive electronics or medical equipment rather than basic tools, since pure sine output protects gear that modified wave can damage. Blue Sea and Bluewater handle the control and distribution side, with Blue Sea's dual USB charging sockets covering everyday device needs and Bluewater's programmable waterproof switches combining a circuit breaker into a single panel-mount unit. For audio and wiring runs, DS18's marine-grade OFC speaker wire and amplifier install kits come sized by gauge to match your system's current draw.

Before buying, confirm the voltage rating matches your system (12V DC versus 120V AC are not interchangeable), check that wire gauge suits the run length and load, and verify any housing or switch fits your panel cutout or mounting surface. Scanstrut's Roam series housings and power inlets are worth considering if you need a weatherproof enclosure for an exposed location. All products here are sold as genuine items through an authorized dealer, so manufacturer warranty applies. Prices vary considerably depending on capacity and complexity, so narrow your search by application first.
