This 4x4 box was mounted on the end of a wooden box that extended from the attic to an area over an island in a church kitchen. There were 4 hot wires(120V) from 4 different breakers but there were 5 neutral wires from the panel to this box. The EGC was orange from the panel to this box. There was no GFCI protection at all. We removed the whole mess. When the new island is installed we plan to install 2 power poles and run 2 GFCI protected circuits to each pole.
I know that there are times a neutral is shared, and I know that there are times when a neutral is oversized, but what would be the use of an additional neutral? (Was it "borrowed" by another circuit?)
