MCB OR RCCB Different

Question

Accepted Answer

MCB and RCCB are both electrical devices used for circuit protection, but they differ in their functionality and applications.

MCB stands for Miniature Circuit Breaker, while RCCB stands for Residual Current Circuit Breaker.
MCBs are designed to protect against overcurrents and short circuits, while RCCBs are used to protect against electrical leakage or residual currents.
MCBs are commonly used in residential and commercial buildings to protect individual circuits, while RCCBs are often used in areas where electrical shock hazards are present, such as swimming pools or construction sites.
MCBs trip when the current exceeds a certain threshold, while RCCBs trip when there is a difference in current between the live and neutral wires, indicating a leakage.
Both MCBs and RCCBs play a crucial role in ensuring electrical safety and preventing electrical accidents.
