Common Causes and Solutions by Your Fulham Electrician
When an RCD (Residual Current Device) trips, it can disrupt your electrical system and cause concern. RCDs play an important role in protecting you from electric shocks and preventing electrical fires. However, understanding why your RCD trips can help you address the issue quickly.
This article will explore common reasons for RCD tripping, the role of EICR (Electrical Installation Condition Reports) in identifying issues, and solutions to prevent frequent trips.
What is an RCD and How Does It Work?
An RCD detects differences between the live (active) and neutral wires. If current leaks, such as through a person’s body or a faulty appliance, the RCD trips. It disconnects the power to prevent harm.
There are several types of RCDs, including:
- Standard RCDs – Protect multiple circuits.
- RCBOs (Residual Current Breaker with Overcurrent Protection) – Protect individual circuits.
- RCD Main Switches – Used as the main switch for the whole installation.
Why Does an RCD Trip?
An RCD can trip for several reasons:
- Faulty Wiring
Poor or worn-out wiring can lead to leakage currents. This can cause an RCD to trip, even if there’s no visible damage. - Faulty Equipment
Appliances like immersion heaters or heating elements often cause leaks when they develop faults. The RCD detects the leak and trips. - RCD as a Main Switch
When an RCD is used as a main switch, the cumulative leakage across multiple circuits may exceed the 30mA threshold, causing the RCD to trip. This could happen even if no single circuit is at fault.
How Can You Prevent RCD Tripping?
To reduce the likelihood of RCD tripping, consider these solutions:
- Avoid Using RCDs as Main Switches
When an RCD acts as the main switch, small leakages across circuits can trigger it. It’s better to avoid this setup. - Install Dual RCD Consumer Units
Using dual RCD consumer units divides circuits into two groups. If one group develops a fault, it won’t affect the other group, reducing the risk of a total power shutdown. - Use Dedicated RCD or RCBO Protection for Each Circuit
Installing an RCBO or dedicated RCD for each circuit means that only a faulty circuit will trip. This keeps the rest of your property powered.
How Does a Fulham Electrician Test for Leakage?
During an EICR (Electrical Installation Condition Report), a Fulham electrician will use earth leakage testing equipment to detect any leakage in the installation. This test checks if the overall leakage exceeds safety limits. If it does, the electrician can identify the source and recommend repairs.
Why You Should Get an EICR
An EICR is a detailed inspection of your electrical system. A qualified electrician checks the condition of your wiring, circuits, and electrical components to ensure they meet safety standards.
Getting an EICR done regularly can help identify problems early, before they cause major issues. It’s recommended to have one every 5-10 years or when you move into a new property.
The inspection looks for:
- Damaged or outdated wiring
- Problems with the earthing system
- Faulty RCDs
- Potential safety hazards
When Should You Have an EICR?
Consider an EICR if:
- You haven’t had one in 5-10 years
- You’re moving into a new property
- You’re experiencing frequent RCD trips or other electrical issues
- You’ve had recent renovations or electrical work
FAQs About Tripping RCDs and Fulham Electrician Expertise
An RCD (Residual Current Device) is a safety device designed to prevent electric shocks and reduce the risk of electrical fires. It trips when it detects an imbalance between live and neutral currents, which may indicate a fault such as current leakage to the ground.
Random tripping may result from:
Faulty appliances or water ingress into circuits.
Damaged or deteriorating wiring.
Intermittent electrical faults, often requiring professional diagnosis.
Yes, minor electrical fluctuations, accumulated current leakage from multiple appliances, or older RCD models may cause nuisance tripping. Modern RCDs are designed to minimize such occurrences.
As a trusted Fulham Electrician, I specialise in identifying and resolving RCD issues. My approach includes:
Inspecting appliances for faults or damage.
Testing the RCD and circuit insulation resistance.
Checking for moisture in outdoor sockets or wiring.
Ensuring circuits comply with BS7671 regulations.
Contact an electrician immediately if:
The RCD won’t reset after tripping.
The issue persists even after unplugging appliances.
You suspect damaged wiring or water ingress.
