Grounding resistance of metal cable trays

IEC 61537 mandates that trays used for bonding or grounding should have a resistance of less than 0. This ensures that in the event of a fault, the tray can safely carry the current without overheating or failing. The main purpose of. Wire mesh cable trays are widely used in commercial offices, industrial facilities, data centers, and smart building infrastructure because they provide unmatched flexibility, excellent airflow, and fast, adaptable installation. Their open-grid design makes it easy to route, add, or modify cabling. A cable tray grounding is best inspected by searching cable tray sections with bonding jumpers (the thick green or copper wires connecting various sections of the tray) and checking them with a device known as a multimeter. When the connection is very close, and the meter indicates a low resistance. that system to lose its UL Classification.
