　　According to Article 4.3.9 of GB 50169-2016 "Code for Construction and Acceptance of Grounding Devices in Electrical Equipment Installation Engineering", the grounding of metal cable trays should comply with the following regulations: bolts should be welded on the supports and hangers of cable trays, and copper stranded wires with copper noses pressed at both ends should be used for bridging the main body of cable trays. The minimum cross-sectional area of the bridging wire should not be less than 4mm ?. When there is no grounding wire between the galvanized support and hanger of the cable tray and the galvanized cable tray, there should be no less than 2 bolts with anti loosening nuts or anti loosening washers fixed at the connection between them. Article 11.1.1 of GB 50303-2015 "Code for Acceptance of Construction Quality of Electrical Engineering in Buildings": The connection between metal ladder frames, trays or trough boxes should be firm and reliable, and the connection with protective conductors should comply with the following regulations: when the total length of ladder frames, trays and trough boxes is not more than 30m, there should be no less than 2 reliable connections with protective conductors; When the total length is greater than 30m, a connection point should be added every 20m to 30m, and both the starting and ending ends should be reliably grounded. The two ends of the connecting plate between the non galvanized ladder frame, tray, and trough box body should be bridged with protective connecting conductors, and the cross-sectional area of the protective connecting conductors should meet the design requirements. When the galvanized ladder frame, tray, and trough box body do not cross connect the protective connecting conductor, there should be no less than 2 connection fixing bolts with anti loosening nuts or anti loosening washers at each end of the connecting plate. Article 8.7.1 of GB 55024-2022 General Code for Electrical and Intelligent Construction of Buildings: The connection between cable trays should be firm and reliable, and the connection between metal cable trays and protective conductors should comply with the following regulations: when the total length of the cable tray is not more than 30m, there should be no less than 2 reliable connections with the protective conductor; When the total length is greater than 30m, a connection point should be added every 20m to 30m, and both the starting and ending ends should be reliably grounded.

　　非鍍鋅電纜橋架本體之間連接板的兩端應跨接保護聯結導體，保護聯結導體的截面面積應符合設計要求。

　　The two ends of the connecting plate between non galvanized cable trays should be bridged with protective connecting conductors, and the cross-sectional area of the protective connecting conductors should meet the design requirements.

　　鍍鋅電纜橋架本體之間不跨接保護聯結導體時，連接板每端不應少于2個有防松螺帽或防松墊圈的連接固定螺栓。

　　When the galvanized cable tray body does not cross connect the protective connecting conductor, there should be no less than 2 connection fixing bolts with anti loosening nuts or anti loosening washers at each end of the connecting plate.

　　總結：鍍鋅橋架：連接板兩端需用2個及以上防松螺帽或防松墊圈固定，可不跨接接地線，但需確保連接可靠。非鍍鋅橋架：連接板兩端必須跨接保護聯結導體，截面積不小于4mm?。特殊材質（如不銹鋼、鋁合金）：需采用專用接地螺栓孔跨接，確保導電連續性。

　　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.
