Is there a Code or Standard that addresses the issue of underneath a raised floor cabling? :(

IEEE 518-1982 did but it has since been withdrawn. :(


Even though it is shielded cable could cross talk and other EMI still be an issue? :mad:


Does anyone have any ideas?

Bewildered.....
 
Re: DCS Control Room Wiring issue -Raised Floor

What is the rating of the cable jacket...ie what does it say on it? Is it just general communication wire?
 
Re: DCS Control Room Wiring issue -Raised Floor

I looked through Article 725 (I guessed that you were talking about Class 2 or 3 cable) to see if there were specific references to support or securing requirements like found in other articles. I didn't find any.
If I was the AHJ for that installation, and there was not owner's contract specification to require support or securing the cable, I would try to reference 110.12, since spaghetti under a raised floor is not neat and workmanlike.
 
Re: DCS Control Room Wiring issue -Raised Floor

Well the cable is all rated for such and the only real "code" piece I have is 'craftsmanship'. At this stage in the game, I do not want to hold the project up so I guess I will have to live with it.

I do believe all the cable is shielded so hopefully it will not be an issue when the start up comes.

Thanks for your help folks, it is appreciated.

DCS (Distributed Control Systems) Raised Floor
I have installed several Raised Floor Control Rooms for DCS systems.
We always used a cable tray system,and sometime I used the telephone type of cable tray and sometimes we would use a regular electrical type of cable tray. I would never want to see a raised floor system not using some sort of a cable tray system. You know as well as I that it would look
like a Rats Nest if we did not install cable tray.
I have worked in a Raised Floor system that had 4 feet of clearance, meaning that the electrician would be able to work in the Raised Floor area, and you would want to keep the cables in a neat manner for Safety and also that it would show that it was done by a First-Class Electrician.
 
Re: DCS Control Room Wiring issue -Raised Floor

Yes that is what I would like to see, but sadly it is not the case. If I had a 'code' that would force the issue, I would have a chance, but workmanship is not one that I could use at this point. I need the DCS running soon and I was a late arrival to the job, someone just missed it and I am afraid I have to live with it.

Rats Nest it is.....
 
Re: DCS Control Room Wiring issue -Raised Floor

You might want to look into TIA/EIA standard 569 (Pathways and Spaces). I work on government facilities and we always install tray, duct, or cable ladder to provide physical protection for signal and power cabling. Also used to provide EMI/RFI protection.
