& SWITCHES CIRCUIT PROTECTION Best practices recommend every wire, except the engine starting circuit, 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. Blue Sea Systems’ selection of circuit breakers, fuses, fuse holders, and fuse blocks offer a range of choices for main and branch circuit protection. To help in the selection process, Blue Sea Systems developed the Circuit Wizard to determine the correct size wire and fuse or circuit breaker for the application.
