My house has a problem with dimming lights, appliances, etc. For no apparent reason, all the lights will dim, appliances (fan, microwave, etc) will slow down, etc. It is not due to a single circuit, I’ve isolated various circuits via breaker panel and the lights still dim and then brighten. Check the voltage on the main feeders during one instance and one leg was 85V, the other 155V (this was the extreme, usually its around 130/110). Flipped a couple breakers and lights returned to normal and voltage read 122/122. Next time they dimmed, turned off the same breakers but the lights stayed dim. I’ve tried turning off all 220V appliances, turning off the circuits that use aluminum, etc, but the problem still remains. Its as if the problem is with power coming into the house.
Electrical system details: Pushmatic Service Panel (160amp), 1/2 the circuits are aluminum, other half copper. 3-220V appliances / 10 15-20A 115V circuits.
Does anyone know what would cause this?
