What is an RCD Safety Switch?

Posted by Michael Sansom on

An RCD (Residual Current Device), also known as a safety switch, is a safety device that disconnects a circuit when it detects an imbalance of the electric current. The RCD turns the power off to prevent electrocution. You will still receive an electric shock, but the duration will be very short, reducing the risk of serious injury.

Warning – A RCD cannot detect all faults for example if a person receives a shock between the active and neutral conductors, however these circumstances are rarer than the majority of incidents that occur between the active conductor and earth which is protected by a RCD.
