Attaching Cables to Electrical Conduit

Attaching Cables to Electrical Conduit
Can I attach Cat3 or Cat5 cables to an existing electrical conduit?

The National Electrical Code (1999 Edition) states the following (Article 800-52(e)):

"Support of Conductors. .... Communications cables or wires shall not be strapped, taped, or attached by any means to the exterior of any conduit or raceway as a means of support".

Considering this, you have to provide alternative supports for communications cables (J-hooks, cable trays, wire channels etc).

Additionally, check if the space where you pull cables is *plenum*. If it is a plenum space, you have to use plenum cables or enclose cables in rigid metal conduits.
