What are RCDs?
A Residual Current Device (RCD), is a life saving device designed to prevent fatal electric shocks by switching off electricity automatically if there is a fault. They do this by monitoring the flow of electricity from the main switch board and reacting to any imbalance in the current.
Do I have an RCD installed?
To check if your home or workplace has one, look for a ‘TEST’ button on your switchboard or a button marked with a ‘T’. RDCs are not to be confused with circuit breakers and surge protectors. Check the label for ‘RCD’, ‘ELCB’, or ‘safety switch’.
What are the main types of RCDs?
There are various types of RCDs that can be used to make sure that you are always as safe as possible.
These ones are usually found in the consumer unit (fuseboxes) and can provide protection to circuits. Fixed RCDs boast the highest level of protection due to their ability to protect all the wiring and sockets on a circuit and any connected appliances.
Used in place of a standard socket-outlet, these outlets have an RCD built into them. This provides protection only to the person in contact with the equipment, including its lead, plugged into the socket-outlet RCD.
These plug into any standard socket-outlet and are useful when neither fixed nor socket-outlet RCDs are available. Simply plug in your tool or appliance, set the safety switch, and you’re protected.
How often should I test my RCDs?
You should test your RCD at least once every three months to check it works properly. To do this you can press the Test button, if it trips then it is working correctly.
