Ok, so I have been installing low voltage wiring for a while but 99.9 % of all of the new work that I do is in a suspended ceiling environment. I am comfortable with my knowledge in this area.
However we are currently installing in an ancient building that has suspended plaster/sheet rock ceilings. The owner of the building just had it newly insulated and is almost fanatical about us not "mushing" the insulation. So we built a walk way system to get us around the area without damaging the insulation.
We are being paid to remove all of the old wiring (old 25 pairs to anthenol ends) and installing Cat 6 Enhanced for Data and Voice. Client is installing VoIP phone system.
The estimator, being someone of a screw up when it comes to bidding, wants us to just leave the cables lay on top of the suspended ceiling instead of supporting it. When I asked if this was a violation of code, he said no..
So it boils down to this, I know that in a suspended ceiling environment by code low voltage wiring has to be independently supported every 4 to 5 feet.. Etc ET. Al, but I am unsure if this "changes" when you get into a suspended hard ceiling environment.
Can anyone point me to the right direction.. A Website or NEC 2005 section etc to clarify this. I have been caught with code violations because of this idiot before and don't want to go through it again.
Thanks in advance.
