Is it a double pole breaker that was giving you 240volt and then stopped,
or a newly installed breaker that should deliver 240 volt. If it is a new
installation , be sure you are using a double pole breaker, which is one
that connects to two different busses of your panel, as opposed to a split
breaker, which connects to one buss of the panel and has places for two
wires to attach to it

A split breaker gives 0v, hot-hot.

If I wanted to make a wild guess, the OP is probably measuring 120v H-G for
both hots, which is quite correct. OP, you have to measure H-H.



Could also be that half the breaker is tripped.
