10 Common Reasons Why Your RCD Keeps Tripping And How To Fix Them

An RCD, or Residual Current Device, is a crucial safety device that protects homes and businesses from electric shocks and fires. These devices constantly monitor the electric current in your circuits, and if they detect any imbalance or leakage, they swiftly cut off the power, acting as superheroes for your electrical system. However, RCDs can sometimes trip unexpectedly. There is nothing to worry about; they are just doing their job.

Today, through this guide, we will share some common reasons for RCD tripping and provide practical solutions to ensure the safety of your home or business.

The Top 10 Causes Of RCD Tripping And Solutions!

RCDs are safety devices that trip when they detect a fault. Frequent tripping can signal underlying issues. Here are common causes why RDCs trip and their solutions:

Reason 1: Faulty Appliances

The first common reason for RCD tripping is when an electrical appliance malfunctions. This can be a faulty or aged washing machine, oven, blender, or any other device.

Solution: Unplug devices individually to identify the culprit, then repair or replace the faulty appliance.

Reason 2: Overloaded Circuits

Sometimes, connecting too many devices to a single circuit can overload it, triggering the RCD.

Solution: Reduce the load by unplugging some appliances or distributing them across multiple circuits.

Reason 3: Damaged Wiring

Faulty, worn, or damaged wiring can also lead to earth faults, causing the RCD to trip.

Solution: Get the help of a qualified electrician; they will help you inspect and repair any damaged wiring.

Reason 4: Moisture Ways In

When water seeps into electrical sockets, wiring, or appliances, it can create a path to earth, tripping the RCD.

Solution: Fix leaks, keep electrical equipment away from wet areas, and ensure sockets are dry before use.

Reason 5: Rodent Damage

Rodents are uninvited guests. They chew the wires, causing short circuits and earth faults, which can lead to RCD tripping.

Solution: Seal any entry points and consider humane pest control measures.

Reason 6: Faulty RCD

Over time, RCDs can develop internal faults and become hypersensitive, tripping without cause.

Solution: If you find any fault, have a professional test the RCD and replace it.

Reason 7: Deteriorating Insulation

Wiring insulation can degrade in older installations, exposing live parts and causing earth faults.

Solution: Consult an electrician to inspect and upgrade the wiring if needed.

Reason 8: Loose Connections

Sometimes corroded or loose wires and connections can also be the reason to create resistance, triggering the RCD.

Solution: Tighten connections and replace any damaged components.

Reason 9: Capacitive Leakage

Some electronic devices have capacitors that can cause a small amount of leakage current, which can cause nuisance tripping with sensitive RCDs.

Solution: Consult an electrician about adjusting the RCD’s sensitivity.

Reason 10: DIY Electrical Work

Sometimes, incorrect DIY electric work can lead to a fault, which causes the fuse box to trip.

Solution: Always take the help of a qualified electrician near you. They will guide you better with fuse replacements and other electrical work.

How To Prevent RCD Tripping?

While some causes of RCD tripping are unavoidable, there are steps you can take to minimise the risk:

• Regular maintenance: Keep your electrical appliances in good condition.
• Avoid overloading: Be mindful of how many devices you use on a single circuit.
• Protect from moisture: Ensure proper ventilation and fix any leaks promptly.
• Professional installation: Always take the help of a qualified electrician for any electrical work.
• Upgrade old wiring: Consider upgrading your electrical system if it’s outdated.
