distance between comm cables and power cables
distance between comm cables and power cables
(OP)
I am trying to find technical spec or code that gives me an actual distance that power cabling (for equipment or service entrance)and communication cabling must be spaced apart from each other. I am aware that under certain conditions the NEC allows them to be run together. My concern is for noise/EMF and I am seeking a code or standard that specifies any required spacing. Maybe it is in EIA/TIA standards, but I do not have a copy currently. Can someone let me know where I may find this specific data. I know a manufacturers recomendation may cover this, but that isnt what I am seeking..Thanks

Electrical/Comm. cable separation?
RE: distance between comm cables and power cables
I went to the location you specified and there are about 6 posts on June 29th of 09. None of those have anything to do with what I am seeking. Here in washington state I have found a state code that specifies a 2 inch restriction, but I am looking to see if anyone has another standard or national code that may apply.
But thanks for your time to make the reply it is appreciated!

Being that you're in WA state, look closely at your state codes. My little experience with WA, their state electrical codes were far stricter than what's common in other places.

- Voltage and current of power leads (noise source)
- Voltage and current of signal leads (noise receptor)
- Cable type (shielded, unshielded, singled ended ground, double ended ground - noise path)
- and the cable routing (inductive coupling of the current or capacitive coupling of the voltage - noise path)
A manufacturer can define most of these variables for their equipment, otherwise it is up to the installer.
