The outbuilding had its own 200 amp service panel (underground feed wires) mounted at the exterior on a pole. I could peek at the meter feed wires through a crack in the panel gutter… there were only two 4/0 aluminum wires in the gutter. The service panel had its own ground rod. There were 120 volt breakers in both the service panel and the sub panel. It appears that the only path back to the transformer for the neutral current is through the earth. The lights and outlets at the outbuilding were operational.
I see the following issues:
-Missing Neural at service feed
-Abandoned wires at service panel
-Combined grounds and neutrals at sub-panel
Does anyone see anything else. I have never seen a missing neutral before.
