When installing coaxial cables beyond the point of grounding, when is it permissible to support coaxial cables by means of attachment to a conduit or other raceway?
As per 820.133(B), "Raceways shall be used for their intended purpose. Coaxial cables shall not be strapped, taped, or attached by any means to the exterior of any conduit, or raceway as a means of support." It's important to note the requirements of 820.133(B) supersede those outlined in 300.11(B) (see 90.3).
