Hi Matthew: In this house, many of the outlets aren't wired correctly. I don't know why. When I moved my system, one of my surge suppressors said that there was a "wiring fault." I bought a $4 device from Home Depot that you plug into the outlet and it tells you what's wrong. I switched neutral and hot and now the device says that this is wired correctly (however, there are other places where I know there isn't a true ground, but the $4 device says that everythings wired correctly.)
