Repeated grounding of the incoming line to the distribution box

Home / Repeated grounding of the incoming line to the distribution box

Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). 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. Safety of Personnel: By safely channeling fault currents into the ground, proper grounding helps to reduce the risk of electric shock to personnel. First, we review and compare medium-voltage distribution-system grounding methods. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used.
