Cat5 in a warehouse 2

[PeaveyPhones]

I need to install 6 Cat5 cables in a warehouse. The distance is about 50'. 30' horizontal to the workstation, along a concrete wall, then 20' down to the workstation. Electrical circuits/conduit will be installed in the same path, probably prior to the data cable. Is it acceptable to just zip tie the Cat5 to the EMT that the electrical cables are in? .... Ya'll can stop screaming at the computer and cursing my name now. I don't really think this is a good idea. What are the proper ways to do this? Is EMT ok for voice and or data cable? Do I need that smurf stuff? Help.

On a sidenote, caddy does say that about their bridal rings; however, they now manufacture a plastic sleeve that fits around the bridal ring providing roughly a 1" or more base to support your cables, which is about the same as a J hook.

OK, let me make sure I understand this. A cable or cables can be supported by a J hook or ring that is modified with a 1" wide piece of plastic. But if it lays across the truss which is made of two pieces of angle iron that are about 1" apart the cable will be deformed and therefore improperly installed?

well if the trusses where spaced 5' to 6' appart you would be ok

First let me say that the NEC is produced from a safety aspect, they don't even care if what you install per the NEC works. What they do care about is safety, in theory if you install according to the NEC, your installation will be safe. If you want it to work, that's another matter.

Actually, the NEC requires you to support your cables at specific intervals, and it sounded like the red iron was more than 4 or 5 feet apart. As far as the surface are used to support the cable, yes your point is valid. Technically a bundle of wires on the flat side of 1" red angle iron is not going to be any worse than a J hook. However, the NEC requires you to use a listed support. That is a product manufactured and listed for supporting cables, which the red iron likely isnt.

You can't approach all this from a logic stance, sometimes you just have to abide by the rules if you wish to be compliant.

Good Luck!
