| CAT 6 plenum installation standard|
I will be installing Cat 6 Plenum cabling above a drop ceiling. I would like to know if there is a standard on hanging the cable? Do I need to use cable hangers or can I just attach the cable with cable ties to existing structure? How far apart do I have to attach cable ties or hangers. Any suggestions would be greatly appreciated. Also do you know where I can find the standard codes for low voltage installations?

You should attach cables every 3 to 5 feet (1.2 to 1.5 meters). Usually, regular tie wraps (loosely tightened) would work for small amount of cables (<10). Since you do not suppose to attach them to drop ceiling supports, those ties with screw holes work best when installing alongside walls above drop ceiling. If you go over that amount, I would recommend using J-hooks designed for that purpose. Also, attached to the walls.
Electrical code that covers low-voltage installs would be the same NEC 2002 as for power. Also, as far as installation is concerned, EIA/TIA-569-A standard covers the subject. This is not a code though, just a standard. A sort of guidelines, if you wish. You can oder NEC 2002 from Amazon or other bookstore (click here). TIA/EIA-569-A has to be ordered from Global Engineering Documents
