3 Phase Mcb Wiring Diagram. When the control mcb is turned on the control circuits will be charged. By using the the three pole circuit breaker we can control three phase power system and by using the four pole we can control 3 phase 4 wiring system.
On the other hands buildings that need high power in three phase and single phase. Another one is a single pole mcb for the control circuit. The power in the main breaker is then given to various busbars.
In industrial and commercial buildings they need high power.
Another one is a single pole mcb for the control circuit. In today electrical wiring installation tutorial we will show how to wire a three phase consumer unit installation in a multi storey building from utility pole to a 3 phase energy meter 3 phase distribution board and then how to connect single phase three phase loads in a three phase wiring distribution system in home electric supply system. Three phase power from the utilities is connected to the main breaker through three phase energy meter. The figure below shows schematic diagram for industrial three phase wiring.
