How protect AC short circuit

[arch007]

I have 10 ft of wire from the AC inlet to the AC circuit box. If there is a short in this wire the circuit breaker will not protect the boat.

What can I install between the AC circuit breaker and the AC inlet ?

In the ABYC standards you are allowed 10 feet of wire run from the shore power inlet to the breaker. The logic here is that shorts are unlikely in well installed fixed wire runs compared to junctions and panels. Of course nothing prevents you from doing something BETTER than the standards require.

In most cases that wire is protected by the breaker on the shore power supply. BUT... if you use an adapter to plug a 30 AMP power cord into a 50 AMP shore power supply than you are NOT well protected.

The answer is pretty simple, install a breaker as close to the shore power inlet as possible. I did on my boat.

The dock / house is already breakered.
