That’s an interesting aspect. I’d never really thought about whether the NEC considered the mating angle being anything but completely square/perpendicular, between the plug and socket.
The reasons always preferred the ground pin UP are as follows (sorry for the length):
ALL THAT SAID, in a setting, you’re probably better off with the ground pin DOWN, because most consumer-grade electronics and accessories (extension cords, switched taps [so-called ‘power bars’], etc.) assume that’s the way your outlets are oriented. You typically don’t see metal faceplates in a residential setting these days either, outside of some basements. They’re almost exclusively insulating, non-combustible plastics now, like nylon, so the danger of the faceplate falling off and hitting a live prong is no longer present.
Disclaimer: I am not an electrician by trade, though I’m fairly familiar with the NEC, performed industrial installations that have passed inspections, and my EE background should count for something (though I personally know EEs who can’t figure out how to check the oil level on their own car). tl;dr – caveat lector.
Because if it’s tugged from above it helps insure the ground pin is last to leave?
I was going to make the reverse argument till I realized it’s more likely to be pulled up than down…
To be honest, I thought ground pin up was best practice anyways.
NEC doesn’t specify an orientation. ;)
Also, this is how I install ’em, when the faceplate is metal.
