Hey I may not be good, but I'm slow...



I think KentAT is right in calling it a metal wireway Art. 376



725.55(A) Cables and conductors of Class2 and Class3 circuits shall not be placed in any cable, cable tray, compartment,enclosure,manhole,outletbox,devicebox,raceway,or similar fitting with conductors

That has been moved in 2008, to 725.136 but you bring up a good point.

I was wrong when I said.....

...specifically Check out 725.55(H).

The question then becomes are the conductors Article 725 or Chapter 8?

A cable tray is a support system.
No separation is required between cables of different systems regardless of voltage rating, as they are cables. Separation is required for conductors and limited energy, coax or data cables.
The code rules for this are located in different articles and its hard to peel them out.
Most locations will install a divider in the tray, thats typically the easiest way to ensure separation.
 
It doesn't sound to me like the OP is describing a cable tray (support system ) but a wireway ( 376.2 ), which is included in the Art 100 definition of a raceway. Does that make any difference?


Iwire, I'm not sure I was disagreeing with you. I screwed up my original post and it took me a few minutes to fix it... maybe you saw my original post. I left off the last few words... "with conductors" and you don't have it in your quote either. Does the fact that it doesn't specifically include "cables" make it OK to have them all intermingled if they were all cables ?

Truth is, I don't know what I think ( again ). One thing I think I think for sure is:

With the proliferation of limited power stuff these days, 725 could certainly stand to be translated into english ( or some sort of human-ese ). .:)

You can place both power cables and communication cables in the same cable tray without any barrier or separation.

Bob,

Can you point out how power cables are excluded from consideration as conductors?

Thanks, iwire. I think the OP needs clarifying.

mestudentinva:

Please specify the type of your equipment. The manufacturer's designation is probably what counts.

Is is a wireway, as mentioned in your title? If so, then it is also a raceway.
Is it a cable tray?

Hi guys - thanks for your input. Sorry took so long to get back here!

In my original post - the mfg. calls it "ME2 Cable Tray".
Here is what it looks like.
http://cableorganizer.com/cable-trays/ME2-straight.htm

It is basically a stiff wire mesh with square openings about 2"x2" bent into a U shape (gutter like) and a thin sheet metal lid (which may or may not be installed).

(it is different than my other post)

I believe now it is a cable tray.

In my other post(((separate discussion than this))) (http://forums.mikeholt.com/showthread.php?t=98259
) I mentioned the Hammond Lay In wireway - which is listed as UL 870 - which I have found out is either Auxiliary Gutter (360) or Metal Wireway (376) - depending on the application (I'm still not sure which one I fall into yet.)
