RCD's Residual Current Device Offers Protection against Electric Shock
An RCD provides protection against earth faults occurring in equipment and reduces the effects of electric shock on human beings and thus saves lives.
An RCD measures the current flowing in the live and neutral cables and if there is an imbalance, that is current flowing to earth above the RCD sensitivity, the RCD will trip and cut off the supply
