"Holy crap! Ten receptacles in one living room?"
this was a house from the 50's. it is a small ranch, and had i think 4 outlets. if you don't want power strips laying around on your floor, you add outlets where you want them. I also added a few more receps in places where people may not use them, but some would, like below a window in the foyer area. some people light up the windows at the holidays with lights/candleabras, etc, so i put one there, another near the end of the room to plug in a vacuum or floor cleaner, etc so you wouldn't have to move a piece of furniture to access a recep. i used 10 as a round figure, i actually think i have 7, with two being on ganged together for the tv area in the corner on one wall, and on the other wall another near those for more a/v equipment.
at our house right now, i have a single gang outlet with one of those things you insert into the single gang outlet and you get 6 outlets out, and i still need another outlet. i hate power strips. i came home from vacation last time and i had one plugged into a lamp, just to make the cord reach, that's all that was plugged into it, and i came home to the power strip smelling like it was on fire. sure enough, i took it apart, the MOV's inside had melted and melted some of the plastic. I have a whole- home surge protector, so i think this one was just garbage. i refuse to use them anymore.
