What is an RCD?

An RCD is a safety device that is typically connected to a home fuse board. The RCD will either monitor just one circuit or several circuits, depending on what way it is wired up.
Essentially, an RCD constantly monitors the electric current flowing through one or more circuits it is used to protect. If the RCD detects electricity flowing down an unintended path, for example through a person who has touched a live part, or an earthed metal object such as the pipe work in your house, then the RCD will switch the circuit off very quickly, significantly reducing the risk of death or serious injury.
