back to back outlet box
 
I have a single family dwelling with interior sheet rock walls. I am going to install a new outlet box on the backside of a wall that currently has an outlet box. What is the code requirement as to the location of this new outlet box? Can it be installed within the same stud cavity? A minimum distance requirement from original existing box?

Thanks

It will be fine unless its some type of firewall...

There is no code restriction about receptacle boxes on opposite side of wall.
There could be fire code regulations if this is a garage fire wall.

Anyone ever see those 4.5" deep open back to back boxes?
By "open" I mean the one box is open to both sides of the wall.

Back to back boxes
 
The current outlet box is in a bedroom and the ajoining wall is a hallway. By the answers here, I can put 2nd box in the hall wall in the same wall stud cavity as the bedroom outlet without violating an electric code.

Yes, I've used them also...

Don't forget that if your code requires arc fault breakers, you will have to add one at this point to be code compliant... that is if you don't have one already.

He does not have to install an AFCI breaker to install an extra convenience receptacle. AFCI's are required in new construction and additions to existing structures.

If you alter a circuit, then the circuit must meet current code.
