working in a an apartment complex ant we have single phase 120/240. the problem is that in all the apartment i read 120 on bothe phases but zero from phase to phase. one phase is good and one is bad. on the bad phase i read 120 but when i plug something in on a branch circuit of that phase i get a voltage drop, and whatever i plug in doesnt work. it acts like a series circuit some how. power and the main is correct though. does any one have a clue what this could be?
