Check voltage on top side of breaker each leg to ground should read 110 if not check main fuses on incoming side to be sure 220 is present,then check secondary side of fuses 220 line to line 110 from line to ground.I think you will find that one leg is open. Did you use a 1 inch double breaker by chance.You need to use regular double pole breakers so you get volts from both phases,The skinny double breakers are the same width as a single 1 inch breaker but they are running off one phase and that would cause your problem.
