Why Does My Safety Switch Keep Tripping?
What Is A Safety Switch?
A safety switch (RCD) breaks the electrical circuit if the system in the home becomes unsafe and there is a potential for an electrical shock. It is a mechanism to protect the person using appliances (like kettles), power points, or other equipment within the installation.
Without safety switches, you are exposing yourself to an increased risk of electrical shock, equipment damage and electrical fire.

Things That Cause A Safety Switch to Trip
For this to happen once in a while is normal. If you’re continually asking, “Why does my safety switch keep tripping?” it’s best to call in a professional.
Several factors can cause the problem, and it’s sometimes challenging to find the root of the problem.
Faulty wiring can be the most difficult situation to diagnose as you can’t identify everything due to restrictions and concealed sections of the installation. It could be a new section that was connected incorrectly or wiring that’s degraded or damaged over time.
Plugging in a Faulty Appliance
If your appliance is playing up or causes the power to trip while being used this is a good indicator that your appliance is unsafe and should be replaced. See below for instructions on how to reset your safety switch if you incur a faulty appliance.
Ingress of Water
One of the most common faults we come across is equipment affected by water this could be such things as outdoor lights, power points or other parts of the installation exposed to the elements. It is recommended to continually check your outdoor fixtures to ensure that there is no damage or corrosion due to the harsh conditions they’re exposed to.
What Can You Do?
If your safety switch (RCD) trips, you need to find out whether it’s wiring or an appliance. Start by unplugging new appliances and switch on a radio so that you can hear when the power is restored. Then, go to the breaker box and reset the switch.
If you can’t switch it back to the “On” position, you need to investigate more. Try unplugging all the devices in the home and check it again. If that solves the problem, an appliance is probably to blame. Plug them in one at a time to find the guilty party.
If the switch still won’t flip back up, it’s best to leave it off and call in one of our expert Perth residential electricians.
