Running cable along bottom of rafters


Hello,

can cables be run along the side of 2x4s which run along bottom of rafters? Sheetrock will be put up later on - attached to the 2x4s.
These are vaulted ceilings.

I know about the issue with nailing into cables in the walls and the requirement to install nail plates but how does this apply to the ceiling in this case (shown on attached picture)?

I'd like not to drill holes into the rafters to run the cables.

Will inspectors be ok with this?

Thanks

The cables as shown are not far enough away from the nailing surface of the 2x's. You need to be 1 1/4" away or more or you need to install nail plates or a conduit to protect the wiring.

ok, does this mean that I will be ok if I remove them from the 2x4s and attach them to the bottom of the rafters?
I just measured it and I would have 1 5/16" from the bottom of the 2x4 to the cable (12/2 in this case).

Thanks!!

As shown that would satisfy the code. You may want to move the cable a little more off the narrow side of the 2x, ie more centered.
