Home / The three-level distribution box was placed haphazardly on the ground
Quality inspection: Make sure the distribution box and its components meet the standards, check whether the wiring is firm, and whether the materials are qualified. Qualified Builders: Hire an experienced electrician for installation and connections to avoid mistakes and omissions. Next, we describe directional elements suitable to provide ground fault protection in solidly- and low-impedance grounded distribution systems. We then analyze the behavior of ungrounded systems under ground fault conditions and introduce a new ground directional element for these systems. 5M above the ground The main switch is 60A Lighting switch 16A two-phase leakage switch Air conditioning 1.
Generally, first level distribution does not allow direct use of electrical equipment, and second level distribution will be by power equipment because it is three-phase electricity, while third
