I recently received a 220V Level 2 Electric Vehicle car charger as a gift, and it comes with an old 3 prong 220V dryer outlet (NEMA 10-30). I'm currently renting, so I cannot run 220V lines where I'd like to, however the car charger unit says that it can run off of 120-220V.
So, I'd like to wire up a NEMA 10-30R such that I can plug it into a regular house outlet at 120V which would allow me to plug in the car charger. Yes, I realize it will charge slower on 120V than 220V, but I'd like to use it now since I'll be renting for 2 more years or so.
My first thought was to simply connect 120V hot to one of the hot prongs on the NEMA 10-30R, then connect neutral to the other NEMA 10-30R hot, and finally bridge that neutral connection to the normal 10-30R neutral connector.
Am I even remotely onto something here? Someone on Amazon.com's reviews for the car charger said that they did it, however no detail was provided, and Amazon doesn't carry this charger anymore, so I can't go back and ask.
