We have alot of open lanai (porches) closed in and made into what they call a "Florida Room". Many of these are a foam and aluminum panel construction. Along the bottom is a channel for the installation of cables for power and lighting. Per 820.133(A)(1)(2), would coaxial cable be permitted to be installed in these channels along with the NM cable? The section uses the term "conductors" and not "cables". Does that make a difference?

Also, the Exception #1 to 800.133(A)(2) and 820.133(A)(2) read exacxtly the same except for a little comma betwen "nonmetallic-sheathed" and "Type AC". Which one is it suppose to be?

The way the 820 section reads, it appears to be one cable - a nonmetallic sheathed AC cable. The way the 800 section reads, it appears to be two separate cables. NM and AC.

The handbook is no help.
 
Re: Cable Separations

For my buck a conductor is definitely not a cable.
The coax and type NM are, as far as the NEC is concerned, fine in the same chase. Take a look at the definition of type NM cable:


ARTICLE 334 Nonmetallic-Sheathed Cable: Types NM, NMC, and NMS
I. General

334.2 Definitions.
Nonmetallic-Sheathed Cable. A factory assembly of two or more insulated conductors enclosed within an overall nonmetallic jacket.

Re: Cable Separations

So any cabling method is permitted to be in the same raceway, enclosure, etc. with other power limited circuits?
 
Re: Cable Separations

You can run coax, cat5 and NM in the same hole in a stud too. Might not be the best design but it is permissible.
 
Re: Cable Separations

Would 800.50(B) come into play on this?
Or would 800.133(A)(1)(c) Exception 3.
As permitted by 620.36.
