    AbstractThe wiring practices of power neutral -point grounding modes for the sectionalized single-bus connectionthe multi-power supply system and the power supply to common TN system are analyzed and compared to put forward two wiring modes that can meet the code and functions requirements. The common one-point grounding wiring practices are adjusted and optimizedand the scope of application of the two grounding wiring practices are elaborated.
