I just got an advanced OpenEVSE kit.
Chose this one because it is dual voltage, amp rate can be set as needed,
has timer or killowatts selection. It will be dialed down to 16A for Maeve.
I have a 20A, 240V outlet out where the car is parked,
with about 50' of 10ga buried wire feeding it.
The connectors I plan on using for the EVSE plug and receptacle are
Neutrik Powercon True 1: https://www.neutrik.com/en/neutrik/prod ... rcon-true1
These are compact, light, locking, rated IP65,
UL rated, and there are no touchable prongs.
I use these in live audio production.
(Note that the standard Powercon connectors are
not meant for making/breaking live connections.)
Am also making a short adapter cable with Powercon to 5-15P plug.
Will also carry a couple extra plugs to replace the 5-15P for common 240V receptacles.
This plug looks useful as it can do several styles of 30A and 50A receptacles: https://www.ebay.com/itm/WELDER-PLUG-50 ... 0929561309
Am going to customize a 10-50 so it will also fit 10-30.
What is the one other plug you would want to see in an adapter kit?
The 25' J1772 cable that came with the OpenEVSE is really nice.
It has plenty of copper for handling high amp loads, as in 240V, 48A, 1% Voltage drop.
(More than Maeve needs!)
A bunch of adapter information.
Tesla oriented, and still very useful: http://cosmacelf.net/Home%20Made%20Adapters.pdf
Maybe this was posted here already?
Thanks and good health, Weogo
