I would like to install a coffered ceiling in my living room and adjacent dining room. My plan is to use 2 X 4 as the strapping and then tack the finished pieces to the 2 x 4. For lighting, as the ceiling is already finished, I was thinking of dadoing a channel on the ceiling side of the 2x4 to run 14/2 wire through. Is it permissible to run the wiring like this? To be clear the wiring will be on the drywalled ceiling side of the coffer.

Hi Scott,

Yes it is permissible. If you are installing the 2x4s flat, then you will need to use protection plates everywhere that the wire passes through the 2x4.

You should also get an ESA Permit & Inspection for the work you are planning to do. First inspection should be done before anything is closed up.

Hi there,

I think we can help you. Provided you are using approved wiring, it can be on either side of the 2x4, provided there is a fire separation, in this case, the drywall itself.

You will need to take care not to pierce the wire when you affix the wallboard, other than that, you should be good to go!


Note: ensure you comply with local building codes, as they do vary. Most are searchable via Google, etc.

Yes this is allowed. Make sure any wire that goes through the 2x4 has a plate protection the wire.

Also ensure you pull a permit for the work.
