Purpose of RCCB
RCCB is particularly useful in situations where there is a sudden earth fault occurring in the circuit.
electrical shock.
However, if the same circuit is protected with RCCB, it will trip the circuit in fraction of a second thus preventing the person
from receiving an electrical shock. Therefore, it is a good and safe practice to install RCCB in your electrical circuit.
How does it Protect?
The underlying fundamental principle behind operation of RCCB is that in ideal situations the current flowing in to the circuitthrough live (hot) wire should be same as the returning current from the neutral.
