You are not boring me. I enjoy trying to figue out these kind of things!!

Now. In the list you gave, only the refrigerator is a moderately heavy-draw item. The others, (such as the Tivo, cable box, computer, clocks, etc) do NOT amount to any significant draw. Unless you have a LOT of lights on in your bathroom, those don't either.

It IS possible that a number of Apts. Are wired to a few ckts. If this is the case, however, you would have had a problem long before now.

Do you have a service entrance (fuse panel) in your apt?? Or is there a common one , perhaps in the hall, for several apts??

There is a panel in the closet for just our apartment (I think!!)
