Residual current devices are used in buildings to help prevent surges in electricity from tripping electrical appliances and shocking people. These safety switches are important and should be tested frequently to make sure they are working correctly.

Only an electrician can replace RCD switches which are defected but any person can test RCD switches. To test the RCD safety switch follow these testing procedures:
- Find the RCD switches in the electrical switchboard.
- Switch off all lights and appliances in the building by the powerpoint.
- Quickly press the RCD switch test button and it should make a clicking sound and move to the off position.
- Inspect the lights and appliances to see if they are off and are not working while the RCD is switched off.
- Turn the RCD switches back on and contact an electrician if the appliances still work when the RCD was in the off position.
How Do I Test RCD Switches?
Any person can easily test their RCD switches and should be a regular practice. The best ways to test to see if the RCD switches are working is to follow these steps:
- Locate the RCD switches which are most likely located where the circuit breakers are located in the electrical switchboard. Most buildings will have two RCD switches built into them which will protect lighting, power points and other electrical systems.
- Turn off all electrical equipment, appliances and systems around the home through the power points. These can include televisions to the dishwasher to make sure the power supply is not connected.
- The push button test on the RCD switch is often noticeable and is built in when safety switches are installed. Push the button quickly and the RCD switch should switch to the off position. A sound should be heard when the test button is pressed on the RCD switch. The electricity supply to the circuits which are protected by the RCD switch should be disconnected when the RCD switch is in the off position.
- Inspect the lights around the home to make sure they do not turn on while the RCD switch is off. Appliances and other electronics should also be tested to see if they work with the safety switch off.
- Once every appliance and system has been tested, switch the RCD switches back on. They should be easily flicked from the off position to the one position and the power points and lights should work again correctly.
How Often Should I Test My RCD Switches?
It is highly recommended that RCD switches are tested every three months to guarantee that they are working properly. At the start of each season is a good reminder to ensure that the RCD switches are tested. The process is quick and is important in preventing people from receiving electric shock or appliances tripping.

- When testing the RCD switch the switch does not automatically switch to the off position or make a clicking sound.
- When seeing if appliances and the lights are off while the RCD switches are off and they still work then the RCD has defected.
- Electrical surges are common or there is an abnormal amount of heat generated by the switch.
