Think of the RCCB as a much more advanced and sensitive version of the ELCB, offering even better protection against electric shock. Just like the ELCB , the RCCB keeps an eye on the electricity flowing in the live and neutral wires. RCCB works based on the principle of Kirchhoff’s current law. The law states that the incoming current must be equal to the outgoing current in a circuit. RCCB thus differentiates the deviation in current values between live and neutral wires. RCCB Definition: A Residual Current Circuit Breaker (RCCB) is defined as a safety device that detects and interrupts a circuit when there is a leakage current to the ground. RCCB or RCD is the new name that specifies current operated (hence the new name to distinguish from voltage operated). The new RCCB is best because it will detect any earth fault.
