Question for those more electrically inclined than me... I'm trying to figure out how I'm going to charge when I visit my parents' house. (I'm also looking into having an electrician install a NEMA 14-50 in their carport, but I'm not certain I can get this worked out.)
They have a NEMA 10-30 outlet for their dryer, but I'll have to use an extension to get to it from the car. I can't find a NEMA 10-30 extension though. Nor a 6-30 or 6-50 which are also 3 prong (I know I'd have to limit the amperage to 30 with the 6-50).
Wondering if anyone here who knows more thinks I could charge off of a 4 prong connection if the ground wire is not connected, such as by adapting the NEMA 10-30 to a NEMA 14-50 (for which I can get an extension cord)? If I go with the 14-50 I know I will have to keep the amperage down to 30 or below. This would also have the benefit that the extension cord is higher amperage than needed which should help avoid errors I would think.
This is for a model S, but since I doubt anyone has tried this with the S, I'd be happy with an answer for the Roadster. If it works for the Roadster, I'm willing to take my chances that it would work for the S.
