There are parts of the answer in several posts
here. You can buy some 6/32 screws that are
longer than normal and just space the outlet
out further, if necessary.
If it's in just a bit too far you can just back
out the existing screws. They're normally about
3/4", so there's some play there.
You can also add an extender, if necessary.
Ideally the tabs will sit on the wall surface so
that you can tighten down the screws. It sounds
like you either have no tabs or the opening is too
big. If the opening is too big you might be
able to build it up with some plaster or durabond,
but that's not critical. The plate screw will prevent
the outlet from pushing in once it's finished, if
you don't use an extender and you can't easily
rebuild the opening.
Where I live, the code requires an extender only
if the wall material is flammable. (Tile, no. Wood
panelling, yes.) The idea is that it's possible for
a spark to happen. (It used to be a big problem
with aluminum wiring.) And if a spark does happen
it shouldn't be able to hit something flammable.
But more to the point is that the contacts should
be wrapped with electrical tape. I rarely see
electricians do that, but if they're wrapped then
there's no risk of sparking or of kids getting their
fingers zapped. Also, if it were already wrapped,
you wouldn't need to shut off the breaker. You
probably won't need to anyway, if you're careful,
but that's up to you.
What I'm saying is that the code *might* require
an extender in your case, if you want to go by the
letter of the law, but if it were me I'd just make sure
to wrap the contacts with electrical tape, then back
out the screws as needed.
