How to measure the grounding resistance of a cable tray
Measure the electrical resistance of the grounding path. Resistance values should meet project or code requirements (often low resistance values required for. 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. Unlike dimensional or surface inspection, grounding performance cannot be judged visually and must be verified through measurement and testing. Here's a basic guide on how to measure. It is essential that the grounding of cable tray systems, including the cables in the tray systems, is inspected for compliance with the grounding requirements in the National Electrical Code (NEC) BEFORE the cabling in the tray is energized and BEFORE cable is installed. If cable is installed. A Megger, or Megohmmeter (also known as Megger earth tester), is a specialized instrument commonly used for insulation resistance testing, but it can also be employed for measuring ground resistance and testing the earthing or grounding system to ensure that it is within acceptable limits and.
