Insufficient cable tray grounding occurs when grounding is improperly executed, deteriorates, or is altogether absent. This can lead to equipment failures, safety risks, and regulatory violations. The use and installation of cable trays is covered by legally enforceable OSHA regulations in 29 CFR 1910. Safety of a cable tray is not a matter of compliance with codes, but a matter of saving human life and billions of dollars' worth of infrastructure. Poorly fitted trays may serve as a fuse in case of a short or a top chimney in case of a fire. Most of the electrical engineers show their curiosity in getting experience on cable tray installations service or task. Cable trays effectively lift cables off the floor, eliminating the risk of employees tripping over loose wires and causing potential injuries. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system.
