Locate the Grounding Point: Open the distribution box and identify the grounding bar (PE bar) or terminals marked for grounding. This is the designated point for connecting the main ground wire and any equipment grounds inside the box . Connect the Main Ground Wire: Use a yellow-green insulated copper wire of appropriate cross-section (typically 6 mm² internationally or 10 AWG in the US). Strip the wire end, insert it into the PE bar or grounding terminal, and tighten the screw firmly to ensure a reliable connection . Ground Electrical Components: Any internal components that require grounding should be connected to the PE bar using copper wires. This ensures that all metallic parts are at the same potential, reducing the risk of electric shock or equipment damage . Verify Grounding Quality: The total ground resistance should be low (typically <0.1 Ohm for industrial systems). Ensure all connections are clean, free of paint or oxidation, and clearly labeled for maintenance . Additional Precautions: Avoid connecting to rusty pipes or sequential links that could increase resistance. For cable shields, keep grounding wires short (under 20 cm) to prevent inductive effects at high frequencies. Multiple parallel grounding points are preferred over a single sequential chain .
The grounding wire in a distribution box must be connected to the PE bar or designated grounding studs, with all internal components also bonded to this point. Use proper wire type and size, ensure firm connections, and verify low resistance to maintain safety and effective grounding .
