Some of us conversion hobbyists upgraded our charging inlets to J1772 but kept our Manzanita Micro PFC series chargers, which though being the most versatile chargers on the planet (AC or DC input, 12-360V), are non-isolated and rather unreliable on commercial J1772 stations, both with Manzanita internal upgrades and 3rd party spoof boxes such as from Tuscon EV.
As such, we often use J1772 cords with no proximity or pilot signal plugged directly into the wall!
I'm 95% sure I've plugged that hot wire into MR BEAN before with no effect. I believe it is because the J1772 pilot signal not only brings in the offboard EVSE contactor, but also the onboard relays that energize the battery charger, so you can't get AC power without having the charger energized.
On a related note, attempting to pull 120V loads from a 240V commercial EVSE (using a spoof box) will trip safeties unless it is multiple 120V loads that are very well balanced between the two hot legs. For the moment, this prevents enterprising RV owners from camping in our charging spaces!!
