Hi all, I've got an old 100 amp panel with pushmatic breakers. My water heater and clothes drier are on a 220 breaker that is not resetting properly. I was informed that they can seize up due to age and not being reset periodically. Its also been raining buckets here (so cal). I wonder whether spraying WD-40 in the breaker might drive out any moisture that may be in there and lube the internal mechanism of the breaker thus allowing it to reset. Several electricians have suggested I should upgrade to a 200 amp panel, but $2k is tough at present and I'm hoping I can get the breaker to reset then deal with just getting the one problem breaker replaced for much less$ . Need your expert advice. thanks
