Has anyone be able to charge using a NEMA 14-30 outlet? I should be taking delivery of my Model S very soon! I planned to use a nearby 14-30 dryer outlet to charge using the mobile connector until the High Powered Wall Connector gets delivered and installed. However the 14-30 mobile connector plug adapter is not available yet. I could get a 3rd party 14-30 to 14-50 plug adapter or wire in a 14-50 outlet in place of the existing 14-30 but my breaker feeding the outlet is 30 amps. Will the mobile connector (or car – not sure where the intelligence lives) be smart enough to detect that I have a 30 amp circuit and charge at 30 amps, or does it assume a 50 amp circuit and charge at 50 amps because the mobile connector is using a 14-50 adapter? Clearly the latter would trip the breaker and not be a viable solution.
