Grounding of the outer guardrail of the primary distribution box
Grounding of the units: 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. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. 8 kV) feeder outlets of HV/MV Substations down to SEC Customer interface including KWH-Meters and meter boxes. Safety of Personnel: By safely channeling fault currents into the ground, proper grounding helps to reduce the risk of electric shock to personnel. IN ELECTRICAL STATIONS INCLUDING TRANSMISSION AND DISTRIBUTION SUBSTAT GR THAN 8 FT FROM THE FENCE. THE FENCE SHALL BE GROUNDED SEPARATELY FROM THE GRID UNLESS OTHERWISE NOTED ON THE A PROPRIATE PROJECT DRAWING. First, we review and compare medium-voltage distribution-system grounding methods.
