When you press a switch the current starts flow from line to earth. All circuits are fed via an overall isolator and selected circuits fed additionally via the rccb. Rccb test circuit wp ad camp 2 working principle of.
And circuits fed via the rccb are socket outlets garage circuits.
Rccb senses the difference between current values in phase and neutral and breaks the circuit in case of an imbalance. Then rccb trip the circuit. Rccb means residual current circuit breaker. As rccb cannot give protection from short circuit and overload faults so generally rccb is always used with mcb.
