I am planning to install a Tesla Wall Connector (WC) in an outside location that has snow and ice in the winter. For reasons of EVSE weather protection, security, and esthetics, I would like to enclose the WC and 24-ft.cable completely in a large metal cabinet, approximately 24x20x8 inches, mounted on a metal post. I've decided to use the WC corded into a 14-50 outlet inside the cabinet. The Wall Connector Installation Manual (https://www.tesla.com/sites/default/files/pdfs/wall-connector-eu/tesla-8...) states that it should be located "in a well-ventilated area. Avoid installation in an enclosed box... Protection from rain is recommended."
Since "avoiding a box" and "protecting from rain" are somewhat at odds, my question relates to how much heat the WC creates when operating. In a box that large, would this really be a problem? Is there any other reason it needs to be "well-ventilated"? If necessary, I can use a cabinet louvered on the sides, but those are not as readily available and are extra expense.
I know many people use the WC outside without protection, without problems, but that is not the point of my question. The question is, can it be put in a box?
