Code for Ethernet / AV
FWIW,
I asked a licened electrician associate of mine the same question with regard to my basement, specifically, running rough-in wires through PVC (1-1/4" sched 40), and leaving an empty (same spec) pipe with pull strings for future expansions, proximity to A/C, HVAC and flourescent fixtures. I was told....
- keep parallel runs of ethernet, telco and co-ax a minimum of 12" apart from A/C
- keep cross-overs between lo-voltage and A/C as close to 90-degree, right angles, as possible
- do not run A/C and lo-voltage through the same holds drilled through studs
- that there were no restrictions regarding running through PVC
no mention of code requirements/restriction was made, however since SP, above, has referenced an NEC chapter, it would be good to check out.
