Believe it or not, there is no standard orientation for common duplex receptacles. I know of no standard or recommendation in the NEC or from a receptacle manufacturer. In patient care areas hospitals often use a receptacle having an isolated ground (i.e., the equipment grounding wire is not bonded to the conduit, but is run through a dedicated ground wire). There is a generally accepted designation for such receptacles - an orange or other colored triangle on its face. The receptacle may also be marked with the letters "IG" meaning isolated ground. For whatever reason, all such receptacles that I have seen have printing that is oriented with the ground hole "on the top". Larry Lippman @ Recognition Research Corp.
