I recently ordered a LR Model 3 and the latest EDD is Aug 21-Oct 2. At my house, the previous owner had a Chevy Volt and a NEMA 6-50R Hubbell outlet installed in the garage. It has been over 8 years since it was last used, so i'm going to have an electrician take a look at it to make sure it's ok. I'm new to this, but from reading a few posts it sounds like the 14-50 is more common. Should I have any concerns about trying to use the 6-50R? Also, would I just need to buy Gen 2 6-50 adaptor and the Mobile Connector (assuming it gets back in stock)?
