No, but some installations such as hospitals might dictate the ground
up preference. Some equipment designed for hospitals and such might
have cords with right-angle plugs on the end which expect the
ground-up orientation. As someone else has mentioned, there may be
locals codes to consider where NEC is agnostic on the matter.
You are probably right, your friend is probably wrong, and his
enforcement official should be able to cite an official local code to
remove the 'probably' from those statements. If he does cite a source,
I would like to see it because no such source has ever been cited
before as far as I know.

I replaced the cord on a really old, almost jet engine strength, floor fan
many years ago. I don't recall where I got the cord from, but the plug
is designed for ground pin up.
OT, but here's a plug-socket habit/pet peeve of mine:
When plugging a "permanent" item (lamp, clock radio, toaster oven, etc.)
into a duplex receptacle, please use the bottom receptacle to keep the
top receptacle open for temporary use.
That's something I do. Sometimes, I've even changed it in public places.
Unlike a lot of people, my idea of "looks best" depends on practical
things, not silly rules. If you plug something into the top outlet (of a
vertically mounted) duplex receptacle, the cord hangs down across the
bottom outlet making it harder to use.
I'm not sure if I EVER thought it looked best to use the top.

You're partially correct. The ground pin is not known as a neutral pin.
The flat blade that's currently made wider than the other flat blade is
the neutral. While both of them are grounded, the neutral is intended
to carry current, and the ground only carries current in the event of a
fault. It is safer to have the ground on top for the reason you
mentioned, but I know of nothing in the NEC that dictates which way you
mount them, unless it's a recent change.
This was one of my main complaints with electrical inspectors, back when
I had to deal with them. Sometimes they make shit up and claim it's a
code violation, when it isn't. We had an old saying: "Those who can,
do. Those who can't, inspect".

Another option, albeit not real attractive, is to use a weatherproof outlet
(Amazon.com product link shortened)
Plug the cord in, close the cover, and nothing it going to fall between the
plug and the outlet, not even rain.
I suppose you could paint the cover to match the wall. Perfect for those
situations where you're constantly dropping pieces of metal on your
electrical outlets. :)
Thanks all for the replies. Looks like the answer is that there is no
national code (in the U.S.A.) that requires outlets to be oriented in any
One thing that I also noticed in recent years is that there does not seem to
be any one standard way that the 3 prongs on 3-prong plugs are oriented --
including the flush mount type plugs that allow the wire to be parallel to
the wall with the plug plugged in. With those types of plugs, I would like
to be able to orient the outlet so that the plug wire can come up from the
floor or down from the appliance (such as a window A/C) and plug in
correctly. I am probably not describing or explaining this too well.
And, I sometimes thought it would be interesting if all outlets were
designed so that there would be not "up" or "down" position. For example,
if all duplex outlets had the ground pin of each outlet on each end and the
other two prongs in the center, then there would be no "up" or "down"
orientation -- the outlet would look the same regardless of which way it was
installed. But, there would be problems with that idea because that would
result it the hot side screw of one outlet being on the same side as the
neutral side screw of the other outlet in the duplex.
