I needed to add an outdoor charging point for my Model S. The NEMA 14-50 socket is connected to the mains via conduit which enters from the bottom of the waterproof box. The Tesla charging cable exits through a slot cut in the the plastic. The slot (and box) is large enough for me to stow the working end ("nozzle?") in the closed box when I am off for a jaunt and plan on reconnecting when I return.
