An RCD Plug and Connectors are life-saving devices as they are designed to prevent any fatal electric shocks. RCD's offer personal protection to a level that ordinary fuses and circuit breakers are unable to offer.
An RCD essentially is a safety device that switches off electricity automatically if there is a fault. So for example, if you cut through the cable and expose live wires or a faulty appliance overheats causing electric current to flow to earth
It constantly monitors the electric current flow through more than one circuit it is used to protect. It’s able to detect when the current flows through an unintended path, such as a person who has touched a live part, the RCD Adapter will then switch the circuit off to avoid any further risk of injury.
An RCD can protect you from an electric shock and there are various types of RCDs that can ensure your safety:
These socket outlets have an RCD built into them which can be used to place a standard socket outlet. This RCD only provides protection to the person in contact with equipment, including its cable, plugged into the RCD socket outlet.
These adapters plug into any standard socket outlet. Also known as an RCD adapter, they are useful for when neither fixed nor socket-outlet RCD's are available. They provide the same level of protection as the socket-outlet RCD's.
These connectors embed the RCD in a cable for a single device, extension cable or trailing multi-socket. Used in environments where you use faulty electronic devices or moisture is present that could expose a fault.
