Can ground wires be installed in cable trays
All metallic cable trays must be grounded as outlined in NEC Article 250. This precaution helps prevent electrical shocks and equipment malfunctions. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. These systems provide an efficient and adaptable solution for managing a wide range of cables, including power cables, control. Cable tray grounding wire is the safety connection that links your electrical system's cable tray to the ground. When a wire is broken or is leaking power, the EGC captures this energy.
