Short version of the question: What is the best option for charging at 30 amps or less? Longer version: We are getting a Model X later this year, so I've started the process of getting a 14-50 outlet in the garage. That will be very easy for us given our current electric service. I am also expecting to get a Model 3 when it comes out in a couple years. Given that the electrician was coming out and working anyway I figured I'd just have him put two 14-50's in the garage, so that we could park the X easily on either side of the garage now and it would be future-proofed for an eventual second electric car. Unfortunately, after our electrician looked at things, we only have 80 amps of capacity free without having to upgrade electrical panel(s). We'll definitely put in the one 14-50 for now, but there was another option I was curious about. I'm considering putting in two 240V outlets - one 14-50 and one 6-15. This would mean no electrical upgrades needed, easy cable runs, and we can use the Tesla UMC adapter for the 6-15. The downside is obviously the slower charge rate on the 6-15. The Model X will mostly be used for errands around town (kids, shopping, etc.). It will get used for less than 20 miles a day and spends at least 15-20 hours a day in the garage. The 6-15 charge rate of 6-7 miles per hour should be sufficient on average for it. Anyone have experience with using a 6-15 for charging? Also, we could go up to 30 amps for that outlet, are there any good Tesla-approved options for something between a 6-15 and a 14-50?
