Horizontal cable tray lightning protection grounding
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. Power circuit grounding of cable trays is explained in CTI Technical Bulletins, Titles No. 8, 11, and 12, and the National Electrical Code Sections 318-3-© and 318-7. It is also covered in NEMA Standard VE-2. It involves connecting cable trays to the facility's grounding system, providing a low-impedance path for fault currents and protecting personnel. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. 96 regardless of whether or not the cable tray is being used as an equipment grounding conductor (EGC). There are three wiring. Welcome to Harger's Engineers Corner. Please contact us if you have any questions.
