This post is about the complete wiring method of 3-phase 4-wire system wiring controlling through the 4 pole MCB circuit breaker. In this post, you will learn something about the Three phase four wire system control. Last time I published a post about the 3 pole MCB breaker wiring if you did not read it then for better understanding read it.
3 Phase 4 Wire System Controlling From 4 MCB Pole Circuit Breaker
As Supply: Three phases four wire
Breaker: four-pole MCB circuit breaker
Also, read it :
Method of controlling three phase four wire system through 4 MCB pole breaker
First of all switch off your incoming main line supply and after that connect the wires to the breaker as shown in the below image. Just like the below image/diagram connect the In voltage L1, L2, L3 and neutral to in terminals of the breaker and then connect same the out connection wires as shown below.
In the above 4 pole MCB wiring diagram image, I use the blue colour line for phase 1, yellow for phase 2, red for phase 3 and black for neutral. Remember that we use only these colours for 3-phase wiring and if we have 110 or 220 voltage supply then we use black colour wire for neutral and red for phase.
If you learn something from this blog then it will be your kindness to share this post with your friends, and always work carefully in electric wiring. Advance thanks for sharing…….
