My house is about 30 years old. The electrical outlets are 3 prong
and the circuits are all on breakers. One of the circuits in the
kitchen measures 115v but it seems when i put a load on it, like a
hotplate or some other appliance, it takes a long time to heat up
and doesn't fully heat up. It seems like when you put a load on
the circuit it can't supply the necessary amperage. This all just
started a few days ago. I flipped the breakers but still have
problem. Do circuit breakers goe bad? Any other ideas of
what it might be before I have to call an electrician?
Thanks.
