Panels behind the doors... funny you should mention that...
Near me is a retirement home, where the building is as old as the residents, and has had as many face-lifts! As you might guess, wiring in this place is an unfathomable puzzle.
There were a few places where no one could find a way to shut off the power. And, there were a few places where there should have been power, but there seemed to be no way to energise those wires.
Then, one day, "Martha" left the home. A kindly older lady, she didn't like feeling "cooped up" in her room, and always had her door wide open. You can see where this tale is going..... sure enough, behind her door (which opened into the hall), there was a panel that no one knew was there! Martha had been at the home longer than any of the staff; with her door always open, none had ever seen the panel.
