A few guys I work with asked me today if cut-in boxes were only allowed to be used for switches. I guess one of them noticed the box that these came in said "switch boxes" and not outlet boxes. I am not aware of any code requirement for this but maybe it has something to do with the listing of these boxes.
 
All of the cut-in boxes that I have ever used are fine to use with either a receptacle or switch or as just a simple old splice box without a device.

The only code section that I can think of that would not alow a switch to be installed in the box would be 110.3(B) if the box listing didn't allow a switch to be installed.

Just don't cut in a double gang old work box and then put two switches in them with 480 volts between them without a divider like I did recently.

I have used hundreds of them and never a problem.But if the listing says switches only then you need to be nice to the inspector or buy another brand.

As far as buying a different brand that is a problem since I have now looked at four different brands and they all say switch box on them. I almost wonder if this is just a name for these types of boxes. If I install a handy box I don't put a hand in it.......

Ryan, could you please give a code section as to cut-in boxes not allowed in fire-rated walls. I believe I know the reason but as you well know as an inspector that will not be enough. Thanks

It is a UL listing. Not sure where.
 
OK I've seen the picture and looked it up more than once, but for the life of me I can't find it right now.

It states that boxes must be securly fastened to the structure. The box becomes part of the listed assembly.
