Routing coax through small section of cold air return
One last question.
I know that I'll pass a high voltage line while routing the cable. I read that you should keep low voltage cables at least 1 foot or more away from high voltage cables if running parallel, but that is not possible in my case.
I can however run perpendicular, which is recommended. Should I still try to maintain some space between the high voltage and low voltage cables or can they be touching a bit?
