All metallic cable trays shall be grounded as required in Article 250. The EGC is the most important conductor in an electrical system as its function is electrical. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. Prohibited Areas: Cable trays cannot be. Cable tray wiring systems have excellent safety and dependability records. The main purpose of. �, are we really interpreting UL correctly? Consider this: UL only classifies the tray when it is the EGC (Equipment Grounding Conductor) and studies show wire me bonding, not grounding serving as the EGC. Grounding relates to power cables and is governed by NEC 92. 7(B) (see pages 2 & 3 of t is.

Cable trays, commonly used in electrical installations, help organize and protect wiring systems. However, these trays are not immune to safety hazards that could cause system failures, fires, or other catastrophic events. A cable tray is an organized support structure designed to secure and route these insulated electrical cables. It acts as a dedicated pathway for power distribution and data transmission, often supporting cables hidden behind walls or above ceilings.
