15120196 Electrical Load Calcs Install one 240V 50A dedicated circuit with a Tesla Wall Connector on the backside of the Ben Shyy
home. The circuit will be ran from the existing 200A main electrical panel, through the crawl 20805 Garden Gate Drive
space, to the charger location. 2-3'of 3/4" EMT will be used under the Wall Connector to Cupertino, CA 95014
protect the wiring being routed to the Wall Connector. (408) 916-7558
The Wall Connector will ideally be installed under the rear window, as the location wouldn't
be in the way of traffic due to its orientation.
If this is not possible, we will install it higher on the wall between the two windows.
