Incoming supply dropping to 66 volts March 11, 2020 by Questions › Incoming supply dropping to 66 volts 0 Vote Up Vote Down Garmaine asked 4 years ago I have a problem in my house. If I test the incoming supply on top of the main circuit breaker I get 220 volts with the breaker set to OFF position, but if I test with the breaker ON, I get 66 volts. What is the problem here?
