    The fuses protect the charger from damage in case of a short in the output wires. The breaker will protect the battery from damage in case of a short on the input wire. Remember, the battery and the charger are both sources of power. Therefore a direct short on wires leading to either will send power directly to the boat chassis or other wires. That is why each power device is required to have protection (fuse or circuit breaker).

    It depends on the problem. If the charger had a fault that increases the current draw above the 15 or 20 amp house/shop circuit breaker while plugged in and charging, then yes it will trip that breaker.

    If the short happens on the output side of the charger, it’s possible that the house circuit breaker wouldn’t react in time to prevent damage to the charger. That’s why they add the fuses on the output.

    I've had that same one on two of my boats including current one. I think mine was 40amp. Never had a problem with them. I have the 12 volt Ipilot Terrova
