Maybe they changed to code again, but as far as I knew it did not
matter which way they were installed. I always put the ground on the
bottom. They just look stupid the other way. They will work either
way. But the code is what dictates....
When my Dad was much younger, he was stringing a bare wire
in the cellar, and dropped it. By friek chance, it fell
across the two blades of a plugged in, ungrounded plug. He
said that really made a memory for him. I wasn't there,
wasn't yet born. But it left a memory for me.
Put the ground at top, it provides some small protection
from the small risk of dropping a metal something across the
energized flat blades.
SAY what? Please cite section/para. Proposed changes, anything to
verify that from any good source.
IEEE thinking is ground down, so if it "falls out"the ground is the
last connection to break. And at work wherever I've worked I've never
noticed plugs installed in any particular orientation. In fact, that's
where I got my idea to check what's going to plug into it, and orient it
to what the plug might suggest. Another bldg I saw, they used cable
ties to tie the cord to the conduit so it couldn't be pulled on/out etc.
TIA for the references; it'd be nice if they did settle that out once
and for all,

Obviously I don't know the specific situation that you speak of, but
this could be a safety issue.
I once got hung up on a 400 VDC power supply and if a co-worker hadn't
been able to unplug it, I wouldn't be posting this right now.
re: 400V DC? Is that considered HV?
Hmm....let me look back at my post and see where it was that I called
400V DC "HV"...
Looking some more...
It seems I'm having a little trouble finding it.
I wonder if that's because I never said, or even implied, that it was

You must have really wanted to work with HV if you sued to deal with

Preferred orientation then is on the left. More info page 240,

I never paid much attention but just a couple months ago a metal
hangar fell behind a dresser. There was a big flash and a breaker
blew. The plug behind the dresser was not plugged in all the way and
luck would have it the hanger shorted out the contacts.
