Rcd Breaker Meaning. It can also provide some protection against electrical fires. Circuit breakers are safety devices which ensures the safety of equipment and personnel from electric shocks and damages.
An rcd which stands for residual current device is designed for human safety and can often be life saving. A residual current device rcd residual current circuit breaker rccb or ground fault circuit interrupter gfci is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock. Rcd means residual current device and mcb means multiple circuit breaker.
As their name suggests rcds have got to do with current and mcbs are concerned with circuits.
Let s learn more about them. It prevents or minimises the risk of injury from an electric shock if you were to touch anything live bare wires etc. The mccb is an earth leakage breaker also known as a core balance or residual current device. Residual current breaker rcb works on the assumption that the current going to the electronics device must come out from the neutral wire if there is no other way for current flow.
