Heretofore some EV chargers were equipped with a "dip" switch. Various amperage could be selected for the output current. The switch was accessible if the cover of the charger was removed. While not an ideal setup, it was permitted to provide a circuit that matched the output that was selected. When inspecting the EV charger I would ask to see the switch so that I could verify the switch setting. This upset some customers because the installer had to be there to remove the cover.....or at least make two trips....one to remove the cover and one to replace the cover.
There is a new way to control the output amperage of an EV charger. The switch is gone and now the control is an app and a Bluetooth device. An owner has the ability to throttle up or down at will with a cell phone. Therefore the circuit that is provided shall be able to supply the greatest possible setting of the charger. I have encountered several installations that did not do that.
