Re: hybrid cable
I'll ask again same as when you posted this question before- what is the power for that is run with the data?
If you give us some information maybe we can help you. Exactly what are you concerned about?

Re: hybrid cable
There are different types of 'hybrid' cable.
I remember one that was used with the original 'smart house' system that had 120v wires and the control wires in 1 jacketed cable.
There are also fiber optics combined with 120v cables in one jacket cable.
It is hard to speculate without knowing more details as to what was actually used, there are many types, and manufacturers.

Re: hybrid cable
The smart house cable is NMS. There is still an article in the NEC for it. The company that made it went out of business, the article stays as there are still homes wired with it.
But as far as the orginal post, I have not heard of such a product.

Re: hybrid cable
Not to give you a hard time, but why would anyone want to run 120v with the data cable for the computer? Aren't there suitable branch circuits and 120v receptacles in the rooms already??

Re: hybrid cable
Not to mention the fact, that running (presumably ethernet) with power cable, would most likly mess up the data. You would be better off just running conduit for the outlet, and pulling the data cable seperatly, keeping plenty of room between the data cable, and any other wiring.

Re: hybrid cable
I don't think this type of cable should be run in a conduit. If it is in a manufactured jacket it will have engineered separation between the low voltage and the high voltage conductors that would suppress cross talk or allow noise to enter the communication conductors from the power conductors, but if it is in a metal conduit this noise can get reflected back into the data and communication conductors and cause havoc. I do not see in the NEC where it would be allow ether and the fact that 780.6(B) does not reference it being in a raceway but allows it in the same box if listed connections for hybrid cable are used.
And that 780.6(A) requires us to follow the Code provisions applicable to their current, voltage, and insulation rating. which would not allow communications and power in the same raceway. 800.52

Re: hybrid cable
I have used a new power cable named SIMTRA that allows power and data to be pulled in the same conduit in several of my projects. This power cable consist of a barrier that complies with the NEC section 800.52 (A)(1) and is U.L. approved. This barrier absorbs the EMI and prevents distortion to the data cable. A typical application that I used it for was to wire a computer workststion system for a new tenant buildout which saved installation time and conduit. A 20 to 30 percent savings can be reflected to the owner. If you are interested in info on this product I would be more then happy to email you info and contact person for this product.

This might make sense if you were doing a bunch of POS stations like maybe in a supermarket where the only power requirement is the computer, monitor, etc. but I can't see this in something like an office environment where the receptacle and load requirements are diverse. You wouldn't install a dedicated receptacle for a computer today anyway.
Another thing- I can just imagine the IT geeks playing with this stuff.

Re: hybrid cable
Thanks Planas, I think that's what the owner was taking about and probably he could not explain it better. He emphasized everything, "fax, phone, data and power", were in the same box. If that is the case I certainly would appreciate any info you can give me.
