ASD
All my main breakers are dbl pole and the toggles tied together and I would bet $ your main breakers in your panel are as well. If they weren't I would hope the surveyor would have noted that as well.
Your experience as an electrician is likely shore based and there are some significant differences with marine electrical. No criticism of your experience intended. The only reason I kept bringing it up was to make sure you understood the differences and avoided any issues.
You are absolutely correct that neutral is tied to ground ashore but not on the boat. On the boat the neutral is a current carrying conductor. If it wasn't the wire size could /would be significantly smaller without issue.
The fix is fairly simple just add another dbl pole breaker assy and wire the second inlet to it and inlet 1 to the other breaker.
Thank Don.
After reading your post I went back to look at my main breaker panel which contains all the boats AC and DC components like switches and circuit breakers. My boat has two 50 amp shore power connections.
Talking only about 120vAC my panel has 2 zones or groups. One group is the air conditioners, ice maker and battery chargers. The other group is everything else.
All 120vAC breakers on the panel are single pole single throw. All are load and line connections, which feeds a main buss.
There are no neutral connections in this panel. The neutral lines coming from shore power or the generator are connected to a main neutral buss.
I have 2 Load busses, 2 neutral busses, Shore ground buss and a ship strap buss and a DC buss, DC ground buss.
This is the design of my electrical system on my 1988 Camargue. Newer boats may have a different configuration but all the basics are the same. There is no voltage leakage (I had ASD tested) and circuit breakers are tested on a regular bases and replaced if fails. I have never seen any burnt wires (conductors) anywhere on ASD.
I will let you make your own conclusions about my electrical system but everything is labeled, the AC Voltage from the shore power and generator are 6AWG wire.
Quite frankly I am impressed with the way the system is set up. I do wish I had a newer electrical panel that lights up when the door is opened and the next door swings open to allow for maintenance on the back of the panel. My panel takes about 45 minutes to remove and is a pain in the a$$, but top of the line in 1988.
Although my boat is set up for 50amp (an option back in 1988), when I am on shore power I am always on a 30amp connection. Said another way, I don't use 50 amp.
