Scott3 - The EVSE has had an appropriate transformer installed in it. The sparky said they learned early on this needed to be done or the EVSE's would burn out in a week or two.
The powerpoint included in my charging photo has been completed. The sparky came back Monday morning bright and early and installed a 3112 residential outdoor power point into the box mounted on the wall of the house. So it's all wired up appropriately and enclosed appropriately.
The handset for connecting to the 3112 can do 16amps provided I use an appropriate power cord. Most are 10 amps, so I would not want to do 16amps through a 10amp cord.
Thanks for your concern. It looks good here. I'm satisfied this solutions is adequate.
The unit from Juicepoint looks good! I might get one of those anyway as a backup.
I've had a look at the Juicepoint web site. It could be a little more forthcoming about pricing. I don't see where you got your pricing. The "Products" tab should let me link to a fuller description of the product and some photos and maybe how to make an order. A couple of greyed-out lines of text isn't very helpful.
