Hello! My car garage electric clothes dryer has the old straight-pin 10-30 plug. Through Tesla, I ordered and received a NEMA 10-30 adapter (the one with that 2 straight and 1 "L" pin). I would like to use my existing 220V 30A wall socket and plan to plug (unplug) my Tesla portable adapter into my dryer wall socket at nights. Can you tell me exactly what adapter piece I would need to buy, so that I can make this happen (safely)? I'm trying to avoid having to spend more money on a Tesla Wall Connector and hiring an electrician, just to add another garage outlet (since I already have an existing 220V wall socket behind my electric dryer). Thank you thank you!!
