When my Model Y was delivered I was set up for charging my 2017 Volt at 240V/16A. That was adequate for charging the Model Y. I was able to add ~5% charge to the Model Y battery pack per hour. Since I already had a 14-50 receptacle on a 50A circuit I was able to swap the 240V/20A EVSE for one rated for 240V/40A. I now charge at 240V/32A. I am able to add 10% charge to the Model Y battery pack per hour. In winter I can precondition while plugged in while maintaining the battery charge even while using 8kW to power and precondition the Model Y. I originally planned to use the Tesla Mobile Connector with the NEMA 14-50 power plug adapter or the Tesla Corded Mobile Connector but these only have an 18 foot long charging cord. I needed an EVSE with a 24 ft or longer charging cord. My original EVSE was made by ClipperCreek. My current EVSE is the AmazingE Fast 32 (this EVSE is sold by ClipperCreek, has a 25 ft charging cord.) I use the Tesla J1772 adapter with the AmazingE unit.
if you provide a close up photo of your existing panel and sub panel perhaps someone on the forum can recommend a solution.
If you follow the earlier thread (the one with the photos) there was already a quote from an electrician that included a 6-20 receptacle. Done and done; just need to decide to spend the $.I mean, apparently 3 different electricians have already evaluated it. I suppose there's a possibility someone here might come up with something none of them thought of, but....
I would save the $500, initially plan to charge at 120V/8A or 120V/12A. You will quickly learn whether 120V charging meets your needs. Then you can decide whether to spend the money for the 6-20 receptacle.Sure - but it would be cheaper to spend $400-500 on a 5-20 outlet, that’s all I was getting at.
