Appliance Tripping Power?
When a specific appliance trips your electricity, it's a sign of a fault that shouldn't be ignored. Our CHAS approved electricians can diagnose and advise.

Why Does My Appliance Trip the Power?
When a specific appliance consistently trips your electricity, your RCD (Residual Current Device) is detecting current leaking to earth from that appliance. This is a protective mechanism preventing you from receiving an electric shock.
Important: If an appliance trips your power, stop using it immediately. Do not tape damaged cables or try to bypass RCD protection – these are serious safety hazards.
Common Appliances That Trip Power
Common Causes
Faulty Appliance
The appliance itself has an internal fault causing current to leak to earth, triggering the RCD.
Damaged Power Cable
A frayed, cut, or water-damaged power cable can cause earth faults when the appliance is used.
Heating Element Failure
In appliances like kettles, washing machines, and immersion heaters, heating elements can fail and cause trips.
Motor Fault
Electric motors in appliances like vacuum cleaners or washing machines can develop insulation faults.
Water Ingress
Moisture inside an appliance can create current leakage paths that trigger RCD protection.
Overloaded Circuit
High-draw appliances on already-loaded circuits may exceed the MCB rating.
Safety Warning
- Never continue using an appliance that trips the power
- Never tape damaged power cables – replace them
- Never bypass or disable RCD protection
- Do unplug the appliance and have it checked
Frequently Asked Questions
Why does my appliance keep tripping the electricity?
An appliance tripping the power usually indicates an earth fault - current leaking to the casing or earth wire. This triggers your RCD protection. The appliance needs testing or replacing.
Is it safe to keep using the appliance?
No. If an appliance trips your RCD, stop using it immediately. The RCD is detecting a potentially dangerous earth fault. Continued use could result in electric shock.
Can an electrician test my appliances?
Yes. We can perform PAT (Portable Appliance Testing) to identify faulty appliances and test your fixed installation to ensure RCD protection is working correctly.

Frequently Asked Questions
Why does my appliance keep tripping the power?
Faulty insulation, a short circuit, or water damage inside the appliance are the most common causes. The RCD detects earth leakage current and trips to protect you from electric shock.
Is it safe to keep resetting the RCD?
Resetting once to identify the faulty appliance is fine, but repeatedly resetting without fixing the cause can be dangerous. If the RCD trips immediately, call an electrician.
How much does it cost to fix an appliance tripping power?
Diagnosis starts at £80 plus VAT. If the issue is a faulty appliance, replacement is straightforward. If the wiring is at fault, repair costs vary from £100-£400 depending on the issue.
Can a faulty appliance damage my wiring?
Yes, a faulty appliance drawing excess current can overheat cables and damage circuits over time. This is why RCD protection trips the circuit — to prevent fire and wiring damage.
