Where should the grounding wire of the distribution box be installed

The grounding wire should be connected to the grounding bar (PE bar) or designated grounding studs inside the distribution box, ensuring a secure and low-resistance connection.Steps for Proper Grounding

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
