I just looked at a job and it is refinishing an attick space. The costomer wants some outlets (1) 14/2, some recessed lights and fan (1)14/2 and some electric heat(1) 10/2.
There is a gunner from the basement to the attick, but it has 2 RG6 coax cables in it. The pipe is an 1 1/4 pvc so i know i have the spce in the raceway, i know your not supposed to run RG6 and romex in the same raceway but..................will I get static or interference on the cable or internet (RG6) if I run the 120v and 240v (heat) in there?

Is this a raceway? or a sleeve? If you fiched the cable and romex in the same wall cavaity is that illegal. You may be right about the coax and 120 v in the pipe but I am not sure if you can't do it. What is that code reference. I think you have a sleeve not a raceway.
 
i wouldnt do it but there are guys that would
dont think its allowed anyway.. 6 in spacing
for phone and cable is best practice

Why is fishing a cable and a Romex in the same wall cavity illegal?

It isn't illegal. That was my point. I was implying if you can run romex in the same cavity as coax then why can't you run the romex in the same sleeve pipe as the coax?
 
This 1 1/4 pvc pipe runs from the basement to the attic. It's not a nipple. I usaually wouldn't do it ( run RG6 and romex in the same pipe) but there is no way to get to the basement from the attic. The boiler is power vented, and the bathrooms are not stacked. This is a pretty nice house so a raceway outside on the side of the house is out of the question. The house is very 'open' with a great room and half walls...so there are alot of load-bearing beams.
My only worry is the interference on the cable/internet line (RG6)?

820.44 is in Part II of Art 820, which is for cables outside and entering the building.
Try looking at 820.133(A) and the exceptions.

Thanks, I knew it was there somewhere.

Would this permit sleeving the coax in ENT within the same PVC?

Sorry I am confused. 820.133 (A) (2) states that coax shall be separated by at least 2 in from conductors... . Except. #1 states UF as an exception. The original post was wanted to know if there would be interference if he put a 10/2 in the pipe with coaxial cable. Am I reading this correctly to mean that if he ran UF in the conduit it would be legal and interference is not a factor. His originally question has not been answered either.
 
If interference isn't a design problem than the two different cables can go in the same sleeve. The 2" limitation is for conductors not cables. And yes, conductors and cables are two different things. As Larry stated, the two different cables could even go through the same hole in a stud.
 
Ok this is all great info......but will the 120v and 240v cir cause interference on the cable and internet line?

My bet is that it won't. The cable is shielded. That should stop interference. I watch cable installers run next to electrical all the time.

Seriously, you'd have to try it to see. 60Hz interference usually manifests itself as two wide bars slowly climbing up the screen.
