This quick and easy 5 minute test could potentially save lives.
We are going to test the RCD at the consumer unit (or fuseboard as some people know it by).
An RCD, or residual current device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire. It can also provide some protection against electrical fires.
It is really important to carry this test out every 3 months to confirm the RCD/RCBOs are still in good working order and providing this essential protection.
I have attached photos of some common RCDs and RCBOs.
Here are the steps for testing these devices.
1. Locate the Consumer unit.
2. Ensure sensitive items of electrical equipment (computers etc.) are shut down/switched off, as power will be lost during the test procedure.
3. Open the front of the consumer/distribution unit and locate the RCDs or RCBOs.
4. Press and release the "Test" button on the RCD/RCBO (this may be coloured or could be labelled "T" or "Test" for example). See photos attached.
The power should "trip" and the relevant toggle switch should flick down.
5. To restore power at the consumer/distribution unit, push the tripped switch back up into the "on" position.
6. Carry this test out every 3 months.
You may also have seperate RCD sockets and switches in the house/garden connected to equipment and should carry this test out in the same procedure as described above.
Again just be aware when testing these devices as it will temporarily disconnect the power to certain circuits in the house which may be supplying important equipment like computers, alarms, WIFI, medical equipment.
If the RCD fails to operate or you are feeling unsure about testing it yourself then feel free to contact me for further information or advice.
