Cable tray grounding 20 meters
Summary: The key to grounding metal trays lies in "starting with 2 points, adding one every 20-30 meters, using 2 anti-loose bolts for galvanized trays, and crossing 4mm² copper wire for non-galvanized trays". Strict implementation can ensure personal and equipment safety. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. The intent of this article is to review grounding practices for cable tray. The core requirements for Cable Tray grounding, as per GB 50303-2015, GB 51348-2019, and CECS 31-2023, can be summarized as "metals must be grounded, connections must ensure conductivity, and multiple points must ensure reliability". The specific provisions and implementation points are as follows:. Cable tray systems have become an essential component in the infrastructure of modern commercial buildings, smart offices, data centers, and various industrial facilities.
