Why Does My Fuse Keep Tripping?
If your fuse board keeps tripping, it’s usually a sign that your electrical system is detecting a fault and shutting off power to prevent danger. While this safety feature protects your home, repeated tripping often indicates an underlying issue that should be checked by a qualified electrician.
Understanding the common causes can help you identify whether it’s a simple fix or something more serious.
⚡ What causes a fuse or circuit breaker to trip?
Modern fuse boards include circuit breakers or RCDs designed to cut power when a problem is detected. Common reasons include:
Overloaded circuits
Faulty appliances
Damaged wiring
Moisture or water ingress
Short circuits
Earth faults
Each of these can trigger the safety mechanism to prevent overheating or electrical shock.
🔌 Overloaded circuits
One of the most common causes is plugging too many devices into one circuit. High-power appliances such as kettles, heaters, or ovens running simultaneously can overload the system.
Try unplugging some devices and resetting the breaker. If the issue continues, further investigation may be required.
🚨 Faulty appliances
Sometimes the problem isn’t the wiring — it’s a single appliance causing the fault.
You can test this by:
Switching off all appliances.
Resetting the fuse board.
Turning appliances back on one at a time.
If the fuse trips when a specific device is turned on, that appliance may need repair or replacement.
🛠 Wiring or installation problems
Older wiring, damaged cables, or loose connections can cause repeated tripping. These faults may not always be visible but can pose safety risks.
If your fuse board trips frequently without a clear reason, it’s best to arrange a professional inspection.
⚠️ When should you call an electrician?
Contact a qualified electrician if:
The fuse trips immediately after resetting
You smell burning or see sparks
Lights flicker or power feels unstable
The fuse board is old or outdated
The issue happens regularly
Ignoring repeated tripping can lead to bigger electrical problems or safety risks.
