Re: N28-2 factory AC wiring

The simple fact is that when everything is working properly, the neutral and ground wires are the same.

The reason they are different is to perform different functions when things go wrong. Since your house wiring is only designed to protect you from things that go wrong _within_ the house, then connecting the ground and neutral wire at the breaker box makes some sense.

However, boat wiring is more complex because a boat floats in electrolyte, and as a result you need to protect yourself and others from more types of electrical interactions than can occur in a house.

You should fix the wiring up to be more correct. If you can budget for it, also get yourself an isolation transformer or some other device designed to protect you from wiring problems with your dock neighbors as well.

I know I harp on this a bit, but Nigel Calder's book does a great job explaining how this works ... much better than I ever could.
