Are you dealing with a fuseboard RCD that keeps tripping for no clear reason? It’s a common issue we’re regularly called out to fix across Snodland and the surrounding Kent area. While it might seem like just an inconvenience, a tripping RCD can be a warning sign of an underlying electrical fault—and it should never be ignored.
At Kent Tech Electrical Services, we’re local, fully qualified electricians based in Snodland, offering expert fault-finding and repair services to both homeowners and businesses. In this blog, we’ll explain why your RCD might be tripping, and what to do next.
What Is an RCD and Why Does It Trip?
An RCD (Residual Current Device) is a key safety feature in your fuseboard (consumer unit). Its job is to detect imbalances in the flow of electricity—caused by things like damaged wiring or faulty appliances—and instantly cut the power to prevent electric shocks or fires.
If your RCD keeps tripping, it means it’s doing its job—but it also means there’s likely a fault that needs urgent attention.
5 Common Causes of RCD Tripping
1. Faulty Appliances
One of the most common causes of RCD tripping is a faulty electrical appliance. Try unplugging all your devices and plugging them back in one by one. If the RCD trips again when a specific item is connected, you've found your issue.
2. Wiring Faults
Wiring can degrade over time, especially in older properties. Loose connections, damaged insulation, or damp in wiring can all lead to residual current leakage, causing the RCD to trip.
3. Overloaded Circuits
Plugging too many high-powered devices into a single circuit can trigger an overload, especially in kitchens or home offices.
4. Nuisance Tripping
Sometimes, overly sensitive or incorrectly rated RCDs can cause nuisance tripping, particularly if multiple appliances start up at once or when using certain types of lighting.
5. External or Outdoor Circuits
Outdoor lighting, garden sockets, or water ingress into external cables can also lead to intermittent tripping—especially after heavy rain.
What Should You Do If Your RCD Keeps Tripping?
Start by unplugging all appliances and resetting the RCD.
If it trips again, try plugging items back in one by one to isolate the fault.
If you can’t find the cause, don’t leave it to chance—call a qualified electrician.
