Isolation Transformer Tripping

[benkay]

Hi all.

Went back to the boat to find no shore power present.

Further inspection found the breaker in the isolation transformer had tripped.

Tried to flick back on, but it trips again straight away, this is even the case with the boat’s RCD/GFCI shut off.

Does this point to wiring problem between the isolation transformer and the boat’s distribution panel? Or point to an issue shore-side of the transformer?

Or of course is it likely possible it’s the transformer itself?

Thanks. Ben

Yes or yes.
NOT an issue shore-side of the transformer.

OK. I worried as much. Now I know at least where to investigate.
