How many cables in 2-gang box?

Is there is a code-enforced limit to the number of cables that you can have coming into a standard depth 2-gang box (a box that would be used for two switches)? I have a box with 5 cables coming into it and I am concerned that (although they will all fit) there will be a code issue.

Thanks,

Steve

What is the volume of the box and what size cables are you using?

Yes, there are code enforced limits. But there is no such thing as a "standard depth" box. Boxes come in all sizes and colors and mnufacturers and materials.

The code limits are based on the cubic inch size of the box (should be stamped on the box) the size of the cable, and the type of the box (and a few other things). However, five 14/2 cables coming into a plastic double-gang switch box is probably not excessive. Give us the details and we'll give you the definitive answer.

5 cables and 2 switches = 10 wires +1 for ground + 4 for switches total of 15.
#12 wire you need 15 * 2.25 = 33.75 cubic inch box required.
#14 wire you need 15 * 2 - 30 cubic inch box required.

Sorry I was slow to answer about the size of the box.

The box is 35 cubic inches (interior) and I am running 12 gauge cable, so it looks like I will squeak in.

Thank you for all your help.

I forgot to add cable clamps. If you have internal cable clamps that is another 2.25.
