So, they were insulated from each other, you could pass + current through one and - current through the other. There is a 3rd terminal, on the inside, that ties directly into a steel stud. That would be a logical ground. I agree with Robert, this would be excellent for a field telephone connection as well as an external power port.

It's much too heavy for a telephone connection point! I'm fairly sure it is intended to supply 12V power to the penthouse when that's in use. The wingnut terminals are typically those used for slotted-lug connections on the various "Batten, Terminal" strips. Are they marked with + & -?
