I think the architect and the client would have a fit if I told them I want to put a 1600A switchboard on the side of their new building. A 1600 Amp switchboard is usually about 8' tall and at least 36" deep. I guess I am trying to minimize the amount of stuff that has to go on the outside of the building. And the local power company won't consider putting meters inside the building even in a dedicated room with an outside door.
