Are you surmising ... in the guts of the (simplified) emergency EVSE they assume 120V AC input, and use that to create 12VDC (and possibly 5VDC) to power the micro-controller ? Hmmm ... yes that could present a problem. (I was hoping for zero mods of the guts.) So, unless they design the US, Euro and Japanese versions input voltage tolerant and with PSU components that auto-adjust ...
Most 12v supplies are universal, if there is GFI then it will have more to do with that component.
