Tele. Coax and other low voltage

[butch]

How close can One get to our stanard romex?With these low voltage wires?

Re: Tele. Coax and other low voltage

As close as you want. They are permitted to occupy the same hole if you wish. However, from a design and performance perspective it may be better to have separation between the two.

I believe that 800.52(A)(2) & 820.52(A)(2) requires 2" minimum.

Ron,
Take a look at Exception #1 to the sections that you cited. Also note that those are the 2002 code sections. The same rule in is the .133 sections for the 2005 code.

Don,
Thanks, I just re-read the exception and the other post (occurring at this time too).
Yes, my reference is from 2002, thanks.

Exception No. 1: Where either (1) all of the conductors of the electric light, power, Class 1, non?power-limited fire alarm, and medium power network-powered broadband communications circuits are in a raceway or in metal-sheathed, metal-clad, nonmetallic-sheathed, Type AC, or Type UF cables, or (2) all of the conductors of communications circuits are encased in raceway.

Why not? The power is NM cable.

Re: Tele. Coax and other low voltage

Sorry Don, I updated my previous post.

The wording is weird. I wonder why they list metal-sheathed, metal-clad, nonmetallic-sheathed, Type AC, or Type UF cables? Isn't AC cable also metal sheathed? Isn't UF also nonmetallic-sheathed?
Is the cable sheath around a coax (or any low voltage) cable considered nonmetallic-sheathed?
