Secondary grounding of the three-level distribution box

26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. 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. Knowledge of the various types of system grounding and performance characteristics is critical when designing or operating an electrical system. The voltage, system arrangement, loads connected, and continuity of. This paper is intended to address how grounding system effectiveness affects each of these goals. SEC Distribution System extends from the MV (33 kV, 13. Each DISTRIBUTION BOX and control...
