#What is an RCD?

An RCD is a residual current device. It is a safety device designed to reduce the risk you of getting an electric shock. When the RCD detects electricity flowing down an unintended path it will switch the circuit off very quickly, to reduce the risk of death or serious injury.

#What does an RCD do?

As a life saving device, it can switch off electricity automatically if there is a fault. If for some reason the outbound chord goes into the water or you happen to pick it up with wet hands, the RCD may shut off stray currents before they can electrocute you or cause fire.

An RCD is a very essential piece of equipment you need to have on the site. It is also a requirement on building and commercial work sites. You can plug it on the wall, be it in a house, building site or commercial premises.. If you don’t have control over the electrical circuit within a particular building or structure, an RCD can assist in this area.
