[QUOTE="ProDave, post: 245471, member: 6969"] Doh yes.Wet Fish In which case the OP's description "there is a red link from L1 supply side to A2 " is wrong, it MUST be a 230V contactor. and A2 must connect to neutral, one would hope from the single phase board (but I guess not since the black is not terminated in the single phase board, so we have a borrowed neutral) Still replace the stuck contactor, check the switch and separate the contactor and alarm circuits and sort out that borrowed neutral.
