I made an error today while fixing the garbage disposal.
I replaced the fried wall outlet that was the cause of the problem, wired it correctly, but installed it upside down...

Will this matter?

Used a GFCI, ugly grey, was cheaper than white or almond...
It's under the sink, so you can't see it....

Well it almost does not matter. Is the ground at the top or bottom. Ground at the bottom is old school. Ground at the top prevents something like a paper clip or bobby pin dropped between the plug and outlet from contacting hot without popping the breaker.

It makes no difference-there's no such thing as upside down. I never met an electrical inspector that cared either way-just as long as they were wired correctly and worked.

Hospitals seem to like having the ground on top. They're somewhat crazy.

Correct, most commercial electricians install ground plug up, residential ground side down

It is not addressed in the NEC (was raised and rejected)

18-36 Log #3897 NEC-P18 Final Action: Reject
(406.4(B))

_______________________________________________________________
Submitter: Ronald Standley, E Light Electric Services
Recommendation: Add new text as follows:
Exception No. 1: Where metal cover plates are installed, receptacles shall be
mounted such that the ground pin opening is above the hot and neutral
openings.
Substantiation: If multiple failing conditions are encountered (i.e., plug not
fully inserted, metal cover loosens, etc.) it is possible that the metal cover
could contact the hot conductor creating a short circuit and a fire hazard.
Panel Meeting Action: Reject
Panel Statement: This proposal is not substantiated with incident data
indicating burn or electrocution exposure or the circumstances surrounding
such incidents.
Additionally, the proposal only addresses receptacles installed in a vertical
plane. How does one insure in a receptacle mounted on a horizontal surface
that the ground pin opening is above the hot and neutral openings?

I have always wired disposals direct with a wall switch.

Most electricians will say that the only thing that matters is that all of them (in the same business or residence) are all installed the same, either up or down doesn't really matter, just that all of them are either up or down.

Some electricians will install a receptacle that is on a switch with the ground hole up. They can be installed sideways also.

Upside down receptacles and tan wire nuts seem to be the hallmark of professional electricians.

yes,, mine was done that way when we had the remodel done. Had to get used to it but no problem now.

I have the one outlet for my gas dryer upside down intentionally, since that's the way the cord seems to be wired. Presumably the manufacturer thinks I want to put it on the same outlet as my washer. Other than that, all of mine are right side up. It makes no difference if it's upside down, as long as it's wired correctly!
