I can't wait for your plans. +1

lincomatic said:Jack,
So if I understand you correctly, you mod is going to require a 4-wire power source H-N-H-G, so that you can tap off 120V from H-N to power the 120V control board? This is a cheap way to do it, but it will limit its portability, since a lot of 240V receptacles don't have a neutral wire.
I haven't taken mine apart, so I don't if what I'm proposing is feasible or not, but it seems a more straightforward method would be to just patch in a 240V-compatible switching supply for the controller. The current 3-wire input is 120V H-N-G. I'm assuming H-N are going through the CT for the GFI. So if you use a pigtail to connect H-H-G for 240V, the GFI will still work properly. No other jumper needed.
Would this work, or am I missing something?

Ok, I see there could be some use for this if you were at a place that had only 240vac outlets, and you wanted to plug in the EVSE, but it is not the same as evseupgrade.com because that unit actually passes the 240vac to the onboard charger instead of 120 like your describing. Great work on getting your EVSE working so you can use it at home as well as at your parents house. I'd still suggest the upgrade as it will also charge twice as fast.
