Re: Climma Air Conditioning from shore power

Thanks Andrew and Eric,
I am in the process of getting a new pump/motor. With the suggestions and help from the group, I took the Calpeda pump out and isolated the winding leads and got the following readings :
Main windings
Green1 to Green2: 12.7Ohm
Green1 to ground: 290 Ohm
Green 2 to ground: 277 Ohm
Starter windings
Red to Black: 17.1 Ohm
Red to ground: 260 Ohm
Black to ground: 277 Ohm
The relatively low resistance to ground would explain why the Amel breaker on the 220 panel was tripping upon plugging in West coast 220 power with two hot legs, as one leg would be going through 280 ohms resistance to ground. When powered from the generator that would be a neutral leg and would not draw enough current to trip the breaker.

Now the challenge is getting the replacement pump/motor here at a reasonable cost. I’m trying a Mexican Calpeda distributor in an attempt to avoid exorbitant Mexican import duties.

Yes Andrew the generator is 220VAC, 50 Hz.
