How do RCDs work…

Electrical accidents are a lot more common than you may think…

in the UK Every year, around 70 people die and 350,000 are seriously injured in electrical incidents in the home. Many of these incidents could be prevented by having RCD protection.

How do RCDs work:

An RCD constantly monitors the electric current flowing through one or more circuits it is used to protect. If it detects electricity flowing down an unintended path, such as through a person who has touched a live part, the RCD will switch the circuit off very quickly, significantly reducing the risk of death or serious injury.
