Grounding Construction Process for Distribution Boxes
Proper grounding of distribution boxes requires correct material selection, secure bonding, low-resistance connections, and adherence to electrical standards to ensure safety and system reliability.Material and Connection ConsiderationsMaterial Consistency: Use connectors that match the enclosure material (e.g., stainless steel) to prevent electrochemical corrosion .Contact Surface Preparation: Remove coatings or oxide layers from connection areas to reduce contact resistance. Applying conductive paste can protect against moisture and oxidation .Flexible Bonding: For moving parts like hinged doors, use flexible copper braided tape to maintain stable contact .Fastening: Employ anti-loosening washers to prevent loosening from repeated door operation .Grounding Wire and Resistance RequirementsWire Sizing: In the US, a 10 AWG (5.26 mm²) ground wire is standard; in other markets, 6 mm² is typical . For connections between mounting plates and spindles, larger wires (e.g., 16 mm² or 6 AWG) may be required depending on cable length and number of spindles .Resistance Limits: The total grounding resistance should be very low, typically
