I think it's against code to lock out a panel so that would not work either. To me they should just put a small sub panel in each room, I would hate to not have access to my own electrical panel. Never know if you trip a breaker or something you want to be able to easily go flip it back on.
Ah yeah forgot about that whole code thing.
Obviously the point being, don't put big control things near the hands of hoards of students.
I mean, my freshman year we had a fire alarm because one of the students decided he wanted to take a lighter to a poster in the hallway.
And hell, I don't think any of our buildings have breakers for individual rooms.
Or if they do, we don't know it. I've never heard of anyone tripping a breaker in their dorm room. If power went out, it was a wide area and not a single room.
I know every room I've been in, we've had to come close to pushing limits. But never lost power to a single room.
