I have a customer who told me his lights in his house were flickering. Since then I have been their about 4 times. I did see the lights flicker last time, like a candle in the wind. Anyway, the lights are on about 4 different circuits in a Cutler Hammer CH 200 amp panel. What I have done so far:
switch breakers around to determine it wasn't a breaker problem. Check reading out of meter each line to neutral (124 on each leg). No motor load on any of the circuits in question. Load in panel is balanced, tightened all connections in panel. I am going to go through everything on one of the circuits to see if it will clear up the circuit, I'm starting to think maybe the main could be bad. It doesn't make any sound and I don't want to put a new main in if it is not the problem, I'm just running out of ideas. It's copper romex through out the house. Could a motor load on other circuit (not lights) effect the lights (such as fridge). Help!
