I have a 20amp circuit that once in a while it goes out, does not trip the breaker and a day later comes back on by itself. I disconnected all appliances and removed a gfci breaker, reset the breaker and nothing. I disconnected the hot from the breaker and did a voltage test between the breaker terminal screw and the neutral bar. It reads 118v. I reconnect the hot lead and did the test between the breaker terminal screw and the neutral bar and it reads 2.4v. I move the breaker to another location and did it all over.. Same results. I got a new breaker and repeated the above tests with the same result. A few people mentioned an open neutral.
Even if there was an open neutral, should the voltage reading between the breaker terminal screw and the neutral bar still real 118v?
