Well in a previous boat, I found stray A/C current in the bilge water. In troubleshooting I found the inlet was overheated and further looking found charred wood and charred wiring caused by the inlet resistance. If that inlet had been on this boat without an inlet breaker it may have been a much bigger problem. That is why ABYC recommendations include a main breaker within 10’ of the inlet and my current boat didn’t have one on the second shore power inlet. It does now! I have found other boats, 1 a Carver, that didn’t have a breaker on the second shore power inlet. It is amazing what even some reputable builders do in electrical. And these were from the builders that way.
