Re: SM Climma AC - Calpeda Pump Voltage with Breakers Off
Hi Bill R., I was specifically replying to Gary Silver and his thread on the Calpeda AC Pump. It looks like his last response is imbedded below mine in my email, and my response looks like it is still attached to the main thread in my e-mail inbox. But perhaps in the forum or your email it shows up separately and would thus of course it would be difficult to see the context. As I am remote in the western Carribean, I am pretty limited to my smart phone functionality. In one of Gary's e-mails he expressed interest in what other boats were measuring; therefore my description of measurements were in response to his measurements at the Calpeda AC sea water pump for the various conditions that I described. When the pump was wired but switched off at the breaker I had one set of readings, another when the main 30amp GFCI was switched off, and then when I disconected the supply wires at the pump I had another set of readings on across the three wires. I think that my readings are consistent with US power supply having 220 supplied by 110 on one supply and the other 110 being supplied on the 2nd hot wire 180 degrees off phase. However, I will take your point to check the pedestal and the 60Hz shore power plug (as it was wired by the previous owner :-) ) I also agree with Danny's response supporting full disconnect at the pedistal; however in this case I did my tests carefully with power supplied in order to try to understand and provide some supportive data to Gary's observations. Thanks and regards, Daniel Carlson on sv BeBe SM#387
