　　Summary: Galvanized cable tray: The two ends of the connecting plate need to be fixed with 2 or more anti loosening nuts or anti loosening washers. It is not necessary to cross the grounding wire, but the connection must be reliable. Non galvanized cable tray: The two ends of the connecting plate must be crossed to protect the connecting conductor, with a cross-sectional area of not less than 4mm ?. Special materials (such as stainless steel, aluminum alloy): Special grounding bolt holes need to be used for bridging to ensure conductivity continuity.
