My understanding is that an old work box (metal or plastic) can be cut in to a ceiling or wall to support a device like switches, receptacles, and smoke alarms using the wall or ceiling surface for support. If installing an old work box to hang a fixture the box needs to be supported from a framing member.
I opened up a wall the other day to install a bar box for a wall sconce. Something in the back of my mind says you can use the wall (not framing member) for box support on wall mount fixtures to a certain weight limit. Am I right or wrong? Looking in 314.23 but not finding anything. looking in luminaires but seems to bring me back to 314. Any direction to locate if it's there?
Thank you
