I have a portable dishwasher and there is a 4-pin socket directly behind the dishwasher in the alcove. The plug on this is great because the extension cord should be plugged into this outlet and I can slide the dishwasher up against the wall in the alcove and not worry about damaging the plug or the dishwasher. In addition, the plug rotates freely so it does not obscure other sockets in a 4-way socket.
