I was called to a home last night that had multiple issues across multiple circuits. They had a tile installer working that day and had a lot of equipment plugged into one circuit. It's a 400 amp service that feeds multiple panels. Voltage coming in from the utility is balanced, but something in the main 200 amp panel is causing a voltage imbalance. I get around 90 volts on one leg and around 150 on the other. I ran a separate wire for the neutral for that panel, but did not affect. What could cause this imbalance?
