    Anyone have a cite for the "brick" being a transformer? This is the first I've seen of that. It seems unlikely to me, as the EVSE is the same size, roughly, as the Leaf,s and the Leaf's is definitely NOT a transformer.

    The blue plug on the EVSE is 240 volts and the outlet is 120 volts, do the math, same as the 1772 plug at chargepoint.

    Hi. I'm referring to the other end if the charging cable, the end that plugs into the outlet.

    yup, that's still live, the relay that connects 240 volts to the 1772 is switched on or off by the charging circuit inside the PIP. there's still 120 volts at the end that plugs into the 120 volt outlet.

    using a Kill A Watt meter can verify this

    Hi. The "timer" is built into the PIP console. As to the "hot" it's several hours after the charge was completed, and the hard plastic outer core of the plug (about 2-inches thick) is quite warm, not searing, but to me it should be cold or at least air temperature -- in So Cal in December, say, 60 degrees. I installed two side-by-side GFI outlets fused for up to 20 amps; seems like the one on the left is the "hot" culprit, while the one on the right works colder....

    hmmmmm....two GFI's, one in the brick and one at your outlet,............ anybody?

    That doesn't necessarily follow. The charger, which is built into the car, would be more likely, IMO, to have the transformer than the EVSE. That "brick" is awfully small to contain a 12 amp 120 to 240 transformer.

    Ok, i'm new to this, so please explain to me what "brick" means? I mounted two double-outlets, side by side, with a plastic pull down rain cover, to the side of my house. Next to the driveway. I can charge from any of the 4 total outlets...

    at 240 volts, the amperage is about half (give or take resistance, capacitance, blah blah blah) that's why it takes 2 hours and 34 minutes for me to charge my battery from .5 mile EV and approx 90 minutes at Chargepoint. using a level two outlet.

    see the large, black rectangular object with the amber light on it in the picture? that's what I refer to the "Brick"

    there's a button on the "brick" that tests the GFI in the "Brick"

    Nice pic! Yes the little round end at the arrow is the part that gets "hot"

    I'm not taking credit for the picture, this was from an earlier post in this thread

    could be too many GFI's. It's my understanding GFI's insert a small current from neutral to ground to monitor leakage current, when leakage current reaches a critical levl the GFI trips the circuit and disconnects the hot side of the outlet.

    I don't see how a Kill A Watt can measure the voltage at the end of a J-1772 plug. Once again, I'll be amazed, astounded, if there is a transformer in the little EVSE, that converts 120 volts to 240 to charge the car. And in that case, the term "EVSE" will also be incorrect: it will be an "EVSE/Charger".

    I'll check that out 'cause i've seen/heard the circuit trip using the left side outlet. A little light comes on in-between the two outlets. But funny thing is, the car still receives the full 3-hour charge.

    It can't, but a Kill A Watt meter can measure current from the 120 volt side all the way to the end of the J-1772 plug, which is at 240 volts.
