I installed a low voltage box onto the side of a single 120 v enclosed box. Electrical building inspector flagged a violation and stipulated that the 120v box and the low voltage box need to be separated. Does the code stipulate this?

If the "low voltage" wiring and the circuit wiring are in separate boxes, there is not a separation requirement for the boxes. Ask the inspector for a specific code section. See section 725.55 for more information.

Not following you there. If you modified a box or attached one box to the other, unless they were designed to be used this way you violate the listing. Besides that, I can't see how the plate would fit.

That's probably what the inspector was talking about- those boxes (like most) are designed to be used individually.

There are combination boxes with either partitions or a separate section for LV. That's what you should be using if you want both on a 2G plate.

The add on low voltage box is made by Carlon, is rated for class 2 low voltage and is a single open. It is designed to be attached to a single gang box. When clipped on to a single gang box, the combine structure equals a double gang box. Basically creating a combination box which can be covered with a 2G plate.

I Used The SC100SC By Carlon For Adding On To Existing Electrical Boxes During The Rough-In Stage Of The Last House I Built. They Worked Very Well And Are Listed For The Application.
