POCO will connect the high leg to C phase on the line side of the meter and the load side of the meter will be wired with B and C swapped in the meter to disconnect wiring (pre-wired by the panel manufacturer). WebDec 5, 2010 · If it has a two pole contactor put the high leg on the phase not on the contactor. If it has a three pole contactor put the high leg on the phase that doesn,t have anything single phase connected to it. Which brings up another question. Most 3 phase condensers only use a 2 pole contactor instead of a 3 pole. Why? M Mgraw Senior Member
