Power - When does the room go *boom*?

Nolatron, just read through this thread, and did not see it mentioned to you to make sure you check all other areas of your house to see what is not working when you trip your office breaker. It is not too surprising to find a light or some outlets in a bedroom or hallway directly above or next to the office be tied into that circuit. Catalog EVERYTHING that that circuit handles, not just what is in that room.
