Introduction
A Residual Current Circuit Breakers is another different class of Circuit Breakers. A Residual Current Circuit Breaker (RCCB) is essentially a current sensing device used to protect a low voltage circuit in case of a fault. It contains a switch device that switches off whenever a fault occurs in the connected circuit.

Purpose of RCCB

Residual Current Circuit Breakers are aimed at protecting an individual from the risks of electrical shocks, electrocution andfires that are caused due to faulty wiring or earth faults.

RCCB is particularly useful in situations where there is a sudden earth fault occurring in the circuit.
 
In such situation, in absence of an RCCB in the circuit, an earth fault may occur and the person is at the risk of receiving an
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?

As explained above, RCCB is meant for protection from earth faults and associated risk to human life such as electrical shocks.

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.
 
In case of an earth fault, the current finds a passage to earth through accidental means (such as accidental contact with an openwire etc.). As a result the returning current from neutral is reduced. This differential in the current is also known as "Residual Current".
 
RCCB is designed such way that it continuously senses and compares for difference (residual current value) in current values between the live and neutral wires. Any small change in the current value on account of such event would trigger the RCCB to trip off the circuit.
