electrical outlets in 2 hour fired wall

[anbm]

Are there any codes preventing to install electrical outlets in 2 hour fired wall?

No.
However, each opening can be no larger than 16sq inches.
Openings on opposite sides of wall must maintain at least 24" horizontal spacing.
No more than 100sq inches of opening per 100sq feet of wall.
Those are just the basic requirements

That pertains to metal boxes, if you are using listed boxes that have a 2 hour fire rating the listing will have the required separations from boxes facing the opposite way and any limits to the number of boxes in the wall.

Chris is correct.

For instance, Allied Moulded Fiberglassboxes can be installed within 3" of each other on opposite sides of the wall.

These are building Codes and not NEC codes, is that a fair question?

Correct, that requirement comes from the IBC.

There are many installations an electrician must deal with that involve applicable codes other than the electrical code [building, mechanical, plumbing (Yes), and energy codes are just a few].

Are you suggesting an electrician with a real world problem cannot come here and get help if the answer cannot be found in the electric code?

[BTW - the mechanical and electrical codes conflict with each other with respect to disconnects for rooftop equipment....an electrician can install a disco 100% compliant with the electrical code and still fail his inspection because the mechanical code is more restrictive...shouldn't this electrician be able to get help here?].

I am not sure that the intent of that post was to say that other codes could not be discussed.

I felt that the question was just to clarify that the sections that were being posted came from the building code and not from the NEC.

Don't forget that you cannot old work into the rated will and just use madison clips.
The box needs to be attached to a framing member or else it violates the UL listing of the rated wall.
