A Residual Current Device (RCD) is a critical safety component in your home’s electrical system, designed to protect you from electric shocks and prevent electrical fires by cutting off the power when a fault is detected. However, if your RCD switch keeps tripping, it can be frustrating and disruptive. At RCD Electrical, we understand how inconvenient this issue can be, and we’re here to explain the common causes and provide practical solutions to keep your electrics safe and reliable.

What Is an RCD and How Does It Work?
An RCD monitors the flow of electricity through your circuits, comparing the current flowing in and out. If there’s an imbalance—indicating a fault, such as current leaking to earth—it trips, disconnecting the power within milliseconds. This rapid response is vital for safety but can become a nuisance if the RCD trips frequently. Understanding why this happens is the first step to resolving the issue.
Common Reasons Your RCD Switch Keeps Tripping
1. Faulty Appliances
A common culprit is a faulty appliance, such as a kettle, washing machine, or fridge, with damaged wiring or internal faults. When plugged in, these appliances can cause a small leakage of current to earth, triggering the RCD. For example, worn insulation in an appliance’s cable or water ingress in outdoor equipment can create this issue.
Solution: Unplug all appliances on the affected circuit and plug them back in one by one to identify the faulty device. If an appliance consistently trips the RCD, it needs repair or replacement. RCD Electrical can perform appliance testing to pinpoint the issue safely.
2. Damaged Wiring
Worn or damaged wiring in your home’s electrical system can cause current leakage, prompting the RCD to trip. This is common in older properties where insulation may have deteriorated over time or been damaged by rodents, DIY mishaps, or wear and tear.
Solution: A qualified electrician from RCD Electrical can conduct a thorough inspection of your wiring using advanced diagnostic tools. If damaged wiring is found, we’ll repair or replace it to restore safety and prevent further tripping.
3. Overloaded Circuits
Plugging too many high-power devices into a single circuit can overwhelm it, especially if the circuit isn’t designed to handle the load. While RCDs primarily detect earth faults, overloading can exacerbate underlying issues, causing trips.
Solution: Spread high-power appliances across different circuits. If tripping persists, RCD Electrical can assess your circuit’s capacity and recommend upgrades, such as adding new circuits or upgrading your consumer unit.
4. Moisture in Electrical Systems
Moisture is a major cause of RCD tripping, especially in outdoor circuits, bathrooms, or kitchens. Water can enter sockets, light fittings, or junction boxes, creating a path for current to leak to earth.
Solution: Check for signs of dampness near electrical installations. RCD Electrical can install weatherproof fittings for outdoor areas and ensure bathroom and kitchen electrics meet IP-rated standards to prevent moisture-related issues.
5. Nuisance Tripping
Sometimes, an overly sensitive RCD or one that’s nearing the end of its lifespan may trip unnecessarily, even when no significant fault exists. This is known as nuisance tripping and can occur with older or low-quality RCDs.
Solution: RCD Electrical can test your RCD’s sensitivity and performance. If it’s faulty or outdated, we’ll replace it with a high-quality unit to ensure reliable operation.
