Hi Bill and Eric:
Yes, all the 220 panel CBs are double pole (both Line [brown] and Neutral [Blue] are switched). With all breakers open (tripped) there is still 240 VAC across the blue and brown leads at the Calpeda Pump when hooked to shore power, but not when the genset is running. Looking at the Climma schematic (really more of a diagram) the neutral and safety ground wires are wire straight thru from the "separate source" and the Line [brown] from the separate source is switched by the relays to provide line voltage to the pump when a given unit is switched on. So I can see perhaps that there might be 110 voltage between the blue and safety ground at the pump from this "seperate source" but not the 220 that I am seeing. Olivier, are you there? What is the separate source for the Climma relay box?
I believe that the "other source" supply for the relay box is directly wired from the 220 volt buss just down-stream from the GFCI 30 amp breaker on the side of the 220 volt panel before it is distributed to any of the CBs (Diruptors). The difference between Euro power and US power is noted and somehow plays into this. Will continue to puzzle this out along with you. Perhaps I need to get to sail to some European power, plug in and see if the mystery voltage goes away.
Thanks for your thoughts.
