Learning How To Test Your RCD could just save a life! Just about everybody knows that they have an RCD / ‘safety switch’ installed at their home and take comfort in ‘thinking’ that the safety switch may save their or one of their family members lives, however what most people don’t know, is that they are not completely fail proof and things can and DO go wrong!
So today we are going to teach you how to test your RCD!
It is a national recommendation that your RCD or ‘safety switch’ is tested every 3 months, yet most people have NEVER had their RCD switches tested! The good news is, that you can do it yourself with relative ease by following these simple steps:
How To Test Your RCD Switch
- Plug a small lamp into a power point and make sure it works. Leave it turned on.
- Make sure that electricity is connected to the property and the main switch is in the “on” position. The lamp should be on.
- Turn off all electronic equipment (computers and televisions) etc.
- Push the test button on each RCD. Do not hold your finger on the test button. The RCD should operate (turn off). If it does not operate, it must be checked by an electrical contractor.
- After pushing the test button and the RCDs have turned off, check that the small lamp is now off. Also check that all the lights and power points do not operate. To do this, plug the small lamp into all the power points and turn the power point on. If the lamp turns on, a licensed electrical contractor must be engaged to correct the wiring.
- When finished testing, turn the RCDs back on and check that the lamp works when plugged into a power point.

Sometimes old electrical appliances or a home with old wiring can have a normal small amount of earth leakage current which can trip out your safety switch.
Earth leakage increases with each additional electrical appliance plugged in, so a single meter box RCD protecting all household wiring is more likely to experience nuisance tripping.
If your RCD trips twice for no reason, it would pay to have your wiring and appliances tested by a licensed electrician. Contact us for a free quote and we will let you know what is involved.
