So I am playing around with a 100 A main breaker panel in a residential home. Client said they lost power sometime last night. I checked everything on the service drop, meter socket and panel, ALL GOOD. I start to turn on breakers and the voltage starts going crazy. When all breakers are on, 1 leg is reading around 185V and the other is around 45-50V. Measurements are being taken from Neutral to Line as well as ground to line, no difference. I have seen this when you lose a neutral at the meter or at the POCO point of attachment, but they are all good. I can have an entire Leg energized without a problem, but when I start to turn on breakers from the other leg, that’s when problems happen. Changed the main breaker, same issue. I am wondering if something in the house is going bad and causing issues. Could a bad Electric Hot Watet heater cause a problem? Or a bad range?
