Electrical - Fuse Blocks & Fuses

Marina Supply offers a full line of fuses and fuse blocks for boating and RV's.

Best Practices and ABYC standards state that every positive wire on the boat outside the engine starting circuit must have circuit protection. When excessive current flows in an electrical circuit, wire insulation can melt and possibly start a fire.

Circuit breakers and fuses protect the wire in electrical circuits. Marina Supply offers an extensive selection of circuit breakers, fuses, fuse holders, and fuse blocks gives boaters a range of choices for main and branch circuit protection. To help select the right size wire and proper fuse or circuit breaker head over to Blue Sea Systems Circuit Wizard page to design a safe circuit for your boat.
