I have an outlet in my kitchen which is not working. When I measure it I get 75 volts so there is some power there, just apparently not enough. My main issue is that I am having trouble diagnosing the problem because I cannot turn the power off to the outlet. I turned off every single breaker and it was still registering 75 volts. It was not until I turned off the main breaker switch to the entire panel that the outlet stopped registering 75 volts. One other thing I noticed was that there is a breaker, which I believe is the one that controls the plug, that I cannot turn on. When I tried to turn it on there was some fireworks and it shut itself off. Is it possible that the breaker has been damaged and is allowing some power (75 volts) to go through?
