I had forgotten about that, but just checked about a dozen cords and
found that to be true for all of them.
Even if the receptacle is installed with the ground hole up, and the
cord is falling out (plug angled down as far as possible)?
If does seem like a small thing to worry about. I suppose if the screw
holding the plate on came loose, and the plate slipped.
Sounds like you're comparing non-grounding and grounding plugs. There
would be some difference in safety if the appliance had any exposed
Considering non-grounding receptacles, I suppose there's no real
safety advantage. There would be a convenience advantage, considering
that if the receptacle was installed upside down, you would have to
turn the plug differently than you thought.
Of course, that doesn't mean that air bags are of absolutely no
So think about what you just wrote, RicodJour.
With the most often seen "alien face" receptical orientation, if the
plug were pulled out of the receptical maybe 1/16" and if a metal plate
securing screw was missing and the moon was in its correct phase,
vibration might cause the plate to move away from the wall and drop down
so the upper edge of one of it's holes fell across the still connected
hot and neutral plug prongs. That could cause arcing and possibly a
spark ignited fire.
If the receptical were installed in the "cowgirl position" AND a
grounded plug was "slightly uninserted", the loose plate would fall onto
the plug's ground pin and no problem would ensue. Of course, that would
only happen if the plug HAD a ground pin. It wouldn't help squat with a
two prong (ungrounded) plug.
You left out the tinder under the receptacle from a nearby pencil
Why wouldn't the circuit breaker wouldn't trip in that situation? If
that's not safe enough, put the receptacles with the loose cover plates
and near the paper clip dispenser on a GFI. Hell, put the whole house
on a GFI - that would actually do something to improve safety.
I could dream up a scenario that would compromise any system. Doesn't
mean that it's going to happen, ever did happen, or that my time
dreaming was well spent. This is the alt.home.repair version of how
many angels can dance on the head of a pin.
Absatively right, and all of the recepticals in my home have their
ground pin holes on the bottom, and I'm not about to change them until
my home moaners insurance company says they'll cancel the policy if I don't.
Well, just to satisfy my own curiosity, and because I knew that continuing
this thread would piss off Tekkie and RicodJour even more, I have posed the
question to my local inspectors office. Maybe in a couple of weeks they'll
respond with a nice sensible answer?
With all the time you save doing half-hearted Borg searches and
avoiding Your Friend Google, why stop with a local yokel? Go straight
to NEMA. Contact AHJs worldwide and ask for their justifications for
having a panoply of receptacle configurations.
I've seen the patents for two-prong polarized receptacles that are
rotatable. The part you plug into is part of a sphere that can rotate
inside it's socket so you can have the plug oriented however you'd
like. Haven't seen a 3 prong patent, but then again I didn't look. ;)
I'm not sure anyone manufactures them. Anyone ever seen one of those

I dont think the NEC stipulates either way. Authority having
jurisditction could answer that.
If you have the ground down and the receptacle is loose and the cord
end starts to fall out the ground will still be in. First make last
If you have the ground down and some how or another something metal
falls across the hot and neutral if the cord is not plugged all the
way in it will obviously short it.
6 of this and half a dozen of the other.

There are a lot of people with habitual ways of doing it,
and a lot of rationalization to support those ways, but
no particularly compelling reasons.
Ground up means falling conductors hit the ground first.
Ground down means that if the plug falls out under it's
own weight, the ground is the last to go.
Ground down means it looks like a smiley face and
attracts children. Ground up means that the
short prongs are on the bottom where it's
harder to see them when plugging things in.
I go with ground down because that's what
I'm used to.
If you're not consistant about it, it looks sloppy
and irritates the end-user. Was it me, I'd
pick one direction for normal convenience outlets,
and flip them upside down when I wanted to
signal some special-case ones.
(Like switched outlets, or outlets on a generator,
next time you grab a grounded cord to plug it in,
look at it and see which way you've turned it.
That's how the recepticle should go.
