Home / Optical and mobile cables are laid in the same cable tray
Cable trays are a support system for electrical cables, power, signal, and communication and optical fiber cables. The purpose of this AE Note is to outline the use of fiber optic cables in "tray rated" environments. NEC section 300-8 does not permit any tube, pipe, or equal for water, air gas, drainage, steam, or any service other than electrical in raceways or cable trays containing. en completely installed, without damage either to conductors orstructural system use maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. NEC Article 392 explains cable trays, their components, appropriate wiring methods for cable trays, and instances where they are and are not permitted for use. - Installation of perforated GI Cable tray of size 300 x 50 mm at height ~12 meter on wall and existing metal support structure.
