How To Ground The Distribution Box
The metal box itself should be processed with a "box grounding bolt" (with PE mark), which must be connected to the grounded PE bus with a copper core wire or a special braided soft wire;
Distribution System Grounding
Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions
Grounding in Power Transmission and Distribution Networks
Power transmission and distribution systems are earthed for electric shock and fault protection. This chapter presents the principles and practices of grounding for power systems.
Why are three-level distribution boxes grounded
Electrical power, single-phase or three-phase, supplied to a user as a residence or a commercial building is generally grounded with a “solid ground” connection.
