I worked as an electrician in a hospital for 15 years and we began placing the rec.s with the ground up many years ago. The reason being is that we used stainless steel covers and over time as the receptacles were utilized, the covers would loosen and often fall on the hot and neutral blades of the cord cap. This happens a lot. With the ground up, you have a good chance of it not grounding the hot. Hope this helps.
