Breaker on Hunter 376

[Tristan Simonds]

I have installed and isolation transformer on my Hunter 376 and it trips the breaker in the port lazarette. I am thinking that there is a problem with the transformer and have reached out to the manufacturer (who has been really helpful) but to cover my bases want to be sure that is a 30AMP breaker that came with the boat. Does anyone here have the specs on that breaker? It just say "Hunter" on it, so I know it is most likely original but I don't see the classic 30 written anywhere on it. I would like to avoid buying a new one just because....
Thanks for any insight on this.

Page 65 A of the 376 Manuel Shows it is a 30 amp but it shows a single shore power inlet on that drawing and Fear Knot has double. I run air, water heater, battery charger and everything on the main shore power circuit with the ac side bridged at the main panel, this would approach a 30 amp load.
