Can cable trays be used as lightning protection strips
Where cable tray systems contain only signal and communication circuits that operate at low energy levels, power grounding per NEC Section 318-7 is not appropriate, but cable tray grounding for lightning protection, noise, and electromagnetic interference is necessary. The purpose of a cable tray system is to support, route, and protect cable as part of the cable management system. Through NEMA and the Cable Tray Institute numerous articles, standards, and other general guidance can be found regarding the proper use and installation of cable tray systems. The. Cable trays can be used as the only equipment grounding conductor (EGC), but they must meet certain criteria (only in qualifying facilities, minimum cross-sectional areas, U. classified as to suitability, etc. Because of its closed design, this type of tray should e used in applications where there is minimal risk of heat generation and buildup.
