We have searched all over Google and NEC to get a precise answer. We have a fiber optic data communication cable - extended demark run - that is 30 feet in the air that has to travel approx. 350 feet in a enormous warehouse. We do not want to use just J hooks attached to the IBeam because we do not want to take a chance that the fiber is stressed and in future fails do to sag etc. We would like to know what is NEC qualified and best suited for this run and if we have to ground the cable tray if we use non-conductive fiber composite trays vs galvanized vs other metal? Can we use cable trays that high that the trays are being held by IBEAM clamps/caddies?
Thanks everyone,
