The most common way to install the NEMA 5-15 outlets is vertically, with the two slots above and the round ground pin below. However, in the building where I live, while most outlets are installed that way, the outlets that are controlled by a wall switch are installed "upside-down", with the ground pin at the top which makes it easier to tell which are switched and which are not.
Also, I have noticed that at the (very large) medical center where all my doctors are, all outlets are installed "upside-down". These are the regular outlets where things like PCs are plugged in, and is true both in new and in very old buildings. Anyone have any idea why they would do that?
