a nema 14-50 receptacle and J1772 inlet of quickchargepower and volt/amp meter of ebay to build a J1772 test box.

used a 6x6x4 box from homedepot

position 4: vent required
With li-on batteries used in EV's this is normally never needed (sealed batteries)
but with lead acid it might be a valid condition.

position 5: diode check engaged

I can also use the j1772 cable in my home now as a (rather expensive) 240 volt extension cable ;-)

I received a bunch of electronics yesterday, so up to the next project
 
I did not want to spend the extra money on the J1772 socket so my two simulators have clip leads nd they depend on a knowledgeable user.



I dis use a socket on my second version of my load tester. It is almost the same as my first version except it used two variable heaters instead of a fixed 4800W heater and a 3K, 4K, 5K heater. I now use 2 variable heaters for 3K to 10K loads.
