Code Question for Low Voltage Cables

I am running 18 AWG cable in my kitchen for low voltage lighting. I've never done this before. Should I drill separate holes in the plates or can they share the holes with NM cable? Is the cable required to be secured/stapled at specific intervals? Thanks!

The LV cables can go through holes in the top/bottom plates or studs. They cannot go in the same boxes as line voltage. The cable must be a type rated for in-wall use (much LV cable is not). Generally follow the same practice for securing and supporting as romex.

Electrical code may or may not apply depending on the voltage of the system. Many jurisdictions do not enforce code for LV lighting even if it does technically apply.
