A breakdown of the consumer in several circuits and a corresponding hedging is useful and makes sense in any case. If a consumer / circuit shuts off due to a short circuit or similar, you are not completely "in the dark" and board operations can still be maintained.
Make sure when installing the fuses are easily accessible - it makes no sense to install a flying fuse to a power supply and then hide it behind the wall or ceiling.
Circuit breakers versus fuses
- both are good and useful. High current cables, such as windlasses
and bow thrusters
can be well equipped with fuses. For smaller consumers, circuit breakers
are better. Ultimately it is a question of the money and the price, for deciding which type you choose. When using fuses, a number of spare fuses
on board should always be available and ready to use in any case.
