To clarify, there are FOUR wires between the Main house 200A panel and the 100A barn panel. BOTH panels were installed at the same time about 18 years ago as I upgraded the house to a 200A panel. All was inspected and approved by the County Building Department.
Both legs come into the barn panel to provide 220V. Then a same-size neutral comes in and is connected to the neutral buss, which has a plate connecting both neutral terminal strips on each side of the vertical runs of breakers. Then, the smaller ground wire is connected to the bottom of the left neutral terminal strip, right where other neutrals are terminated from a couple 110V receptacle circuits.
The house built in 1967 was run in romex. About every run is a home run back to the house panel. I ran all 110V in the barn in EMT. I’m having a hard time believing both the electrician and the inspector were wrong, but hey, I’d rather be safe than sorry.
