2003-01-24 When the ground plug first came out, it was common to mount it with the ground hole below the two power slots. Then someone got the idea if the plug is half out of the socket and metal or fingers fell onto the exposed pins, a short or shock would result. If the ground hole was mounted up, it was assumed that anything falling on an exposed pins would hit the ground pin first and be deflected and thus avert a disaster.
Even though the case of such a thing happening is extremely rare, something must have happened if placing the ground hole up is now the preferred way. It doesn't mean it is always done this way. And I'm not even sure if it is part of the national electric code. In reality, I see plugs mounted both ways.
