My EVSE makes a fairly loud click when I plug in to the vehicle. It sounds a switch or contact is being flipped. Is this common? I'm familiar with the car making a bunch of noises but I wasn't ready when the wall unit starts off with a loud pop.

Yes. All EVSEs contain a beefy relay ("contactor") that clacks on after the EVSE recognizes that it is connected to a car and may begin delivering power. When the car is disconnected or there is a fault condition, the contactor is de-energized, cutting off power to the EVSE's connector handle.
