Is you boat 230v circuit and generator a 50hz system?

Would you be so kind as to send me this wiring diagram as a JPG.

I’m hoping someone has run into this before, and can shed some light. I have the feeling the answer is staring me right in the face and I just can’t see it.
For 3 years of owning la Querida SM#207 I’ve always run the heaters and Air Conditioning from generator power. The marina where I was berthed only offered a 30A 120VAC circuit. Now that we’re in Mexico, we’ve had occasion to run the water heater and Air Conditioning
from shore power. It has not gone well. Upon plugging into shore power the breaker on the side of the 220VAC load center in the galley immediately tripped. Mind you this is North American 220(230) VAC with two hot legs and no neutral. Together with an
electrician we found the offending circuit and disconnected the blue (normally neutral) wire and all circuits worked except the Climma air conditioning. Restoring that connection A to B in the diagram above, the Air conditioning works being powered from the
generator. However the main breaker trips immediately when connected to shore power. Power feed “1” comes off the main power distribution, no circuit separate circuit breaker. Power feed “2” comes off the “Climma” individual breaker on the Amel Panel.
Measuring voltage from “B” to a brown junction point reads 125VAC. From “B” to a blue wire junction point (normally neutral) also reads about 125 VAC. “B” to ground is open.
The electrician did his work three ports ago (and we were sailing the next day) when our priority was to get the hot water heater to work without bothering the neighbors with generator noise and exhaust. Now our priority is getting the air conditioning working
from shore power. We’re much further south and the cabin is a sauna most evenings. The previous owner was on board for a week in Zihuatenejo and reiterated he was able to run all circuits (including the air conditioning) from shore power. He also did his
cruising in Mexico with 2 hot leg 230VAC power.
Any tips or similar past experience/solutions would be welcome.

(just back from Ixtapa where the mosquitoes forced us to close the hatches making the problem worse)
