Residual current device, or RCD, is found in fuse boxes. The RCD is a device made to protect people from electric shock. An RCD does this by switching off the electricity automatically should there ever be an electrical fault
Checking on your RCD regularly not only saves money and lives! Even better, it’s one of the easiest electricity checks you can carry out by yourself. Here are the basics of RCD, how they work, and how you can test yours.
How Does An RCD Work?
Residual current devices work by keeping track of circuits for any earth leakage faults. Whenever it detects a defect in the circuit, the RCD will switch that circuit off. Therefore, reducing any risk of electric shock, injury or electrical fire.
Research shows that RCDs are about 96% reliable. However, if homeowners tested their RCD’s more often, this figure would be higher. That’s why it is essential for you to get yours tested every six months.
How To Conduct RCD Tests At Home
- Lift the flap on your consumer unit.
- Identify the RCD switch with a “T” for test indicated on it
- Push the test button to see if all the mechanisms are working as they should
- Make sure that you have the RCD’s circuit breaker switched off, reset the RCD and switch the circuit breaker back on
If the RCD fails to operate or have an uncertain feeling about whether you’re on the right track, contacting a local electrician is the best possible option.
Why Does Your RCD Keep Tripping?
It can get really frustrating when the RCD trips out continuously, especially if you’re coming home a half defrosted freezer. So, what could be the cause of those excessive RCD trips? Here are some causes:
- Faulty appliance: Any electrical appliance, including bedside lamps and washing machines, can cause RCD tripping. Try switching off and unplugging appliances, resetting the RCD and switching everything back on to see if any were the cause of your trip.
- Moisture: Electrical wiring that comes into contact with too much moisture or humidity can cause RCD tripping. By sealing any leaks in bathrooms and kitchens can prevent any moisture coming into contact with wiring.
- Damaged wiring: This could be caused by DIY work such as any nails that were used to hang shelve
