Diffrence between ELCB Vs RCCB

ELCB (Earth Leakage Circuit Breaker) and RCCB (Residual Current Circuit Breaker) are both types of electrical safety devices that are designed to protect against electric shock and electrocution. The main difference between the two is the way they detect and respond to electrical faults.

An ELCB is a type of circuit breaker that monitors the current flowing in the live (hot) and neutral wires. If the current flowing in the live wire is not equal to the current flowing in the neutral wire, indicating a leakage of current to earth, the ELCB will trip and cut off the power supply.

An RCCB, on the other hand, is a type of circuit breaker that monitors the current flowing in the live and neutral wires, as well as the current flowing to earth. If there is an imbalance between these three currents, indicating a leakage of current to earth, the RCCB will trip and cut off the power supply.

In summary, ELCB monitor only current flowing in the live and neutral wires while RCCB monitor current flowing in the live and neutral wires, as well as the current flowing to earth.
