Grounding wire for factory distribution box
Use a properly sized copper grounding wire connected from the distribution box to the factory central ground, ensuring resistance below 0.1 Ohm.Wire Sizing and StandardsFor grounding a factory distribution box, the wire size depends on the market and application:US market: Use a 10 AWG (5.26 mm²) wire for general grounding connections, and 6 AWG (13.29 mm²) for connections between mounting plates and spindle plates in high-current applications .International markets: Typically, a 6 mm² wire is used for general grounding, with 16 mm² for critical connections between mounting and spindle plates . Copper is preferred for its conductivity and corrosion resistance, especially in industrial environments .Connection PointsDistribution Box to Mounting Plate: Attach a grounding wire from a threaded stud at the bottom of the distribution box to the mounting plate .Mounting Plate to Factory Ground: Connect a second grounding wire from the mounting plate to the factory's central grounding point .Optional Spindle Plate Connection: In some applications, an additional wire from the mounting plate to the spindle plate ensures low resistance, particularly for long tool cables or multiple spindles . Use factory-preset studs or welded points on stainless steel enclosures to ensure mechanical stability and low contact resistance. Remove oxide layers and ensure proper torque when tightening connections .Resistance RequirementsThe total grounding resistance between all system parts should be less than 0.1 Ohm .For parallel paths (tool cable and grounding wire), calculate total resistance using parallel resistance formulas to ensure compliance .Material and Installation ConsiderationsCopper conductors are recommended for buried or exposed runs; avoid aluminum for underground connections due to corrosion risks .Use anti-loosening washers and flexible copper braided tape for moving parts like doors to maintain consistent grounding .Ensure all grounding points are corrosion-resistant, especially in high-humidity or outdoor environments .Test each installation to verify resistance meets the maximum allowable limit (typically 25 Ohms for general grounding, but industrial low-voltage systems require
