Differential in circuit breaker wiring diagram:
This diagram shows how to make a Differential in a circuit breaker wiring diagram. In this circuit, we use FP MCB ( Four Pole Miniature Circuit Breaker ), and a differential Switch. Here first we need to connect the MCB with a power source, then connect the differential switch. If you want to know more about this circuit please check our youtube video below the post.

Components used to make the Differential in circuit breaker wiring:
4 pole MCCB for 4-Wires Connections, the one additional 4’th pole for Neutral Wire Connection so that between Neutral and any of the other three will supply. In 4-Pole MCCB the Neutral Pole is also having Protective release as in the Phase Poles. Three Phase Supply with Neutral. TPN means triple pole TP + Neutral which is 3 – phases and Neutral, but the Protection is given for Three Phases only and in 4 poles MCB Protection is given to all 3-Phases as well as Neutral. In the case of a 4-pole MCB, the Purpose is not to protect the Neutral but it is rather to Isolate the Neutral.
02. Differential Switch:
ELCB complete earth leakage circuit breaker works on earth leakage production. Usually, the ELCB circuit breaker has two cables Phase and Neutral if any load is directly connected to the earth without taking neutral from ELCB then the circuit breaker will trip automatically. Earth leakage circuit breakers are used in applications to prevent electric shock and electrical fire caused by a short circuit or overload in the control panel by automatically closing when leakage is detected.
