I have a residential customer (200 Amp Underground service)who complained that when motor loads turn on (dryer,disposal, furnace blower), their lights would get brighter momentarily. I have checked all panel and meter socket connections. The voltage goes up about 15 volts on startup. The service entrance neutral connection was quite loose, but after it was tightened, there was no change. I would appreciate any suggestions.
