    OK, so I'm waiting for delivery and reading the manual...

    It is pretty specific that you should plug the MC into the wall first, then into the charge port. What happens if you are charging in a public NEMA 14-50 outlet, and someone decides to wander over and unplug you from the outlet? And then plugs it back in when they are through? Does it do any damage?

    No, other than to your expected state of charge.

    When you unplug it from the wall when the car is charging, there is likely to be arcing because current is flowing. This can cause fires in extreme circumstances, but generally does no harm. The release button on the car connector stops the current flow and prevents this from happening when you unplug that end.

    Plugging the wall end in last does no harm at all. The UMC takes time to start up, and the car takes still more time before it starts drawing current, so no arcing will occur.
