In North America, if they bridge together the two phases to give you 120V only service, your electric stove, the big one, (and electric water heater if not gas) won't work at all. I don't mean work poorly. I mean zero heat output whatsoever. Of course, a toaster oven or a single-plug-in burner will still work, but you'll have to coordinate.
