Re: Plugging a 120v boat into 240v

What do you think the other possibilities could be?

Re: Plugging a 120v boat into 240v

Now I see what you’re saying, I get it!

(I don’t get what “RDF” means, and neither does Google, but maybe you can enlighten me.)

So, IF the OP actually has a working RCD on his shore supply,...

Re: Plugging a 120v boat into 240v

Yes.

Yes. Not relevant to the discussion, but true.

When it tripped. But with only the main breaker engaged, it did not trip. I am trying to give you a scenario where there could be...

Re: Plugging a 120v boat into 240v

Yes. The point is, you can short a neutral and safety ground together on an RCD and not trip it if there is no circuit to carry any current. Zero current is the purported scenario in the OP's...

Re: Plugging a 120v boat into 240v

I'm not sure that that's guaranteed to be true, although I follow your reasoning and you could well be right.

If the current flow is 0, however, there is no way for there to be any leakage.

Re: Plugging a 120v boat into 240v

I agree, this is a bit surprising. However, RCDs on large 240V and 120V marina circuits in the USA only became a requirement a few years ago. Perhaps this boat has simply not encountered one? I...

Re: Plugging a 120v boat into 240v

No problem, you can frown. But the OP indicates no loads on the circuit, so a lecture on volts and amps is irrelevant here.

Irrelevant. He describes the phenomenon happening on any branch...

Re: Plugging a 120v boat into 240v

Because I read the OP.

Some things you write are true in this paragraph; some are not.

Re: Plugging a 120v boat into 240v

No, in this case the branch circuits are open. There are no loads present.

Re: Plugging a 120v boat into 240v

If there is indeed an RCD at the shore pedestal, the possibilities in order of likelihood in my opinion are:

1. Downstream inadvertent neutral-ground bond. Follow jammer's instructions.

2. ...
