I haven't yet but soon will. All I need is to have a NEMA 14-50 socket installed and appropriate cable and breaker in the panel. My charger just plugs Into a NEMA 14-50 socket, same as what a stove or dryer would use. I can mount the charger on the wall myself.
I'm expecting it to be a bit on the expensive side because I want the full 50 amps to the plug.
I will have Pike's electric do the install. They have done a great job on other projects for me.
