What To Do If Your RCD Keeps Tripping?

Updated: Jan 3

If you are experiencing an issue with your Residual Current Device (RCD) tripping, you are probably wondering what to do next. An RCD is a safety device that is designed to protect you and your home from electric shocks and electrical fires, so it is important to take any warning signs seriously. In this blog post, we will discuss what to do if your RCD keeps tripping and how to work out the cause of the problem. We will look at the different types of RCDs and the most common causes of tripping. We will also look at how to diagnose and fix the problem yourself and when it is best to call a professional electrician. By the end of the post, you should have a better understanding of your RCD and how to troubleshoot any issues.


Inspect the circuit breaker panel

One of the first things you should do if your RCD keeps tripping is to inspect the circuit breaker panel. Make sure that all the switches are in the correct position, and that none of the breakers are tripped. If you do find that a breaker is tripped, try to reset it. If the breaker trips again, it could be a sign of a bigger problem that needs to be addressed by a professional electrician.

Check for faulty appliances

The second step to take if your RCD keeps tripping is to check for faulty appliances. Faulty appliances can draw more current than they should, causing the RCD to trip. Check to make sure all your appliances are in good working order, and if they aren’t, have them serviced or replaced. Also make sure that none of your appliances are overloaded. If you have too many appliances plugged into one outlet, the amount of current drawn could be too high and cause the RCD to trip.


Look for damaged circuits

One of the most common causes of a tripping RCD is a damaged or faulty circuit. If you notice your RCD tripping frequently, it’s important to check all of the circuits in your fuse box for any signs of damage. Signs of a damaged circuit include frayed wires, smoke, sparks, or a burning smell. If you notice any of these signs, it’s important to switch off the power at the main switch and call a qualified electrician to repair or replace the circuit.

Test the RCD

The fourth step in troubleshooting your RCD is to test the RCD itself. Start by unplugging all the appliances connected to the RCD. If the RCD trips again, you can be sure the problem is with the RCD itself. To test if it is faulty, you should use a multimeter to perform a continuity test. Set the multimeter to its lowest range and make sure it is set to measure resistance. Connect one lead of the multimeter to the live side of the RCD and the other to the neutral side. If the resistance is not zero, it means your RCD is faulty and needs to be replaced.

Contact a qualified electrician for assistance

After trying to reset and troubleshoot the problem with your RCD, the next step is to contact a qualified electrician for assistance. An electrician will be able to examine the wiring and circuits in your home and identify any underlying issues that might be causing your RCD to trip. They can also provide advice on how to remedy the situation, such as replacing faulty wiring or even installing a new RCD.

Before you attempt to troubleshoot your RCD tripping, it’s important to ensure that your RCD is working properly. If you’re unsure, it’s best to call a professional electrician for help. Once you’ve identified the cause of your RCD tripping, you can take the necessary steps to fix the issue, ensuring that your home is safe from electrical hazards. Contact us for a quote.
