(D) Not in Vicinity of Easily Ignitible Material. Overcurrent devices shall not be located in the vicinity of easily ignitible material, such as in clothes closets.
I assume you mean a lock on the door so that the door cannot be opened while work is being done on the panel. There is no NEC requirement for a lock. There may be local codes or a regional bias that ask for one.
Don't most bedroom doors have at least a privacy lock?
That would keep someone from swinging the door into you while you worked on the panel.
I may be mistaken but I thought Don was talking about behind the door. If not I agree with you stickboy. I have never seen a panel get rejected in a bedroom. Heck, don't put it in the laundry room either for that matter. We install them in laundry rooms all the time.Don, every room in a residential application would fall under 240.24(D), unless we start providing concrete rooms for panels.
