Well, it
was a window/wall unit, until the advancement in technology that allowed it to become an office celing unit.
(btw), it was connected to a 1 pole 30amp and a one pole 40amp c/b on opposite corners of the panel that just happened to have 208V between them. I have no idea how they controlled that AC unless they shut off one or the other of them. The best scenario
did happen. Less than 2 hrs after I disconnected the power the whole office was in a dumpster, AC and all.
