![]() If you install a current transformer with an ampere meter for measuring running load. Note that the ampere meter and current transformer are 200/5A. And the ammeter will show the total load running ampere. In the blue wire a current transformer install which provides the supply to the Ampere meter. And supply will go to each load from 100 A circuit breakers. And for each 100 Ampere MCCB supply was got from the bus bar. The Neutral wire (black wire) was connected to the bus bar.įrom the Main MCCB circuit breaker, the 3 phase supply goes to the upper bus bars. The 3 Phase Line 1, Line 2, and Line 3 (red, yellow, blue) are connecting to the line points of MCCB circuit breaker. The main 3 phase four wire supply enters the panel board. The wiring connection is started from the main 600 A MCCB circuit breaker. In the 3 phase panel board wiring diagram you will see an Ampere meter with a current transformer connection, some light indicators, and Voltmeters.īelow three phase distribution board wiring diagram shown. And have 5 other 100 Ampere circuit breakers. Which are 3 poles 600 Ampere MCCB circuit breaker. In the diagram, you can see the main MCCB (molded case circuit breaker). 3 phase panel board wiring diagram post is about a three phase panel wiring which is the main distribution board for 3 phase load. ![]()
