I've got a really old combination electrical receptacle that's failing
and needs to be replaced. It's configured with the outlet above the
switch. However, all the current models I've found have the switch on
top. Unfortunately,for my application, I need the outlet on top.

The question is-- can I mount it upside down without violating any
electrical codes?

It wont matter how it's mounted as long as it's wired properly and no
connections are exposed. The code dont specify anything in regard to
mounting positions.

I once lived in a rental house that had 2 switches that were upside
down. (not 3 way). That was not a code violation, but it irritated me,
so I reversed them. Except for 3 way switches, they should always go UP
to turn a light ON. That's just the way it is, and what we're accustomed
to. However, electrically, they work the same way.
