Communication and phone cable support

[mholland]

Our factory has recently made a decision to have all the communication and phone lines that drop from the ceiling, (in open air), to be "ty-rap" attached to the nearby 110v power drops, (buss drop cable). I don't believe this is allowed. What about the 2" separation? Any thoughts?

300.11(C) prohibits cables to be used to support other cables, raceways or other nonelectrical equipment.

Also the 2" separation is for conductors not cables.

How about power poles?
1/2 carries power and the othe 1/2 for phone/data etc.

Power poles have a solid divider to separate the line and low voltage.

Power poles have a solid divider to separate the line and low voltage.

Dividers are not necessary if listed cables for line voltage and communications (example- MC and CAT5) are being used. If the line voltage were separate THHN conductors then a divider must be used between them and the communications cables such as CAT5.

Also, you can't run flexible cordage in conduit or raceway which I believe a power pole would constitute.

You could use a length of strut from the ceiling as a support and ty-rap everything to that.

"Ty-rap" straps are not really being used as a means of supporting the communication cables, but rather a means of keeping the drops attractive and not hanging all over the place. Im not sure that it is truly a means of support. Both the communication cables and the 110v power drops are supported individually from the ceiling.

I think the case could be made that you would be supporting the cables horizontally by the power drops.

If it is holding it in a certain position why is it not support?
