    Reasons for grounding in the distribution box

    Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions such as shocks. Whether you're a seasoned pro or just starting out, this comprehensive guide will give you practical. Grounding systems aren't just boxes and wires – they're the silent bodyguards protecting people and equipment from electrical disasters. When lightning strikes or a rogue voltage surge decides to crash the party, proper grounding steps in like a seasoned bouncer, redirecting danger away from. Safety of Personnel: By safely channeling fault currents into the ground, proper grounding helps to reduce the risk of electric shock to personnel. This helps to reduce the potential difference that exists between conductive parts and the earth. Each DISTRIBUTION BOX and controller must be grounded. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used.
