I found this on web search:

“I'm not a pro, but rather a long-time audio guy and electronics hobbyist. So some of the pros may disagree, but I base this recommendation on my own practical experience.

While code doesn't mandate any separation, IMO good practice calls for keeping electrical wiring and signal or data wiring at least several inches apart where they run parallel.

The problem is the possibility of induced noise in the signal or data cable. The electrical wiring will not be affected in any way.

There is little concern if the wiring is in a grounded metallic raceway, or if the data/signal cable is well shielded. Using thinwall conduit or AC cable instead of NM would take care of the problem easily.

I still wouldn't zip tie an unshielded data or signal cable to conduit, but otherwise you should be fine.

If you're using NM cable, in addition to the separation, I recommend a twist or two per foot in the electrical wires, to help cancel out EM radiation from them.”
