my guess would be well over 100...
i know the room i'm in, basement office, i can count six...
probably 8 plus a 220 in the garage and i know for a fact, my shop in the woods (28 x 48 ft bldg.) at least 25 + 2- 220's, the rest of the house is my wifes, so i could care less how many outlets she has, but i do know, when we built, i went nuts with wire!!!
can't ever have too many, and too few sucks!!!
peace out~
