Several problems can make a home's electricity trip, including too much demand, an appliance fault or a fault in the wiring. What was running and how quickly the power went off help an electrician decide what to investigate. Repeated tripping needs attention, especially if it comes with heat, a burning smell or water near electrical equipment.
Record what happened safely
Note which device trips, what was running and whether it happens immediately or after a while. A photo of the closed consumer unit can help identify the device without removing a cover.
Do not repeatedly reset a device that won't stay on. Heat, a burning smell, water near electrics or smoke mean stop using the affected equipment and seek help; immediate danger needs emergency services.
Several different faults can look like ‘no power’
The home may exceed its contracted power, overload a circuit or have an appliance or wiring fault. The protective device and the timing give clues, but they don't replace testing.
Don't accept a larger breaker as a casual fix. The protective device must suit the wiring and installation. Increasing what it allows without checking those can remove protection the cable needs.
Ask for the cause and the repair
Use an appropriately enabled electrician. Explain changes such as a new hob, heater or charger, and whether the fault coincides with rain or another appliance.
After the visit, ask what was tested, what failed and whether the solution is temporary or complete. Keep the invoice and any recommended follow-up. A reset that holds for ten minutes isn't much of an explanation.

- Danger signs checked
- Unsafe resetting stopped
- Apartment or common fault considered
- Written diagnosis retained
Common questions
Should I replace the breaker with a larger one?
No. Protective devices are selected for the installation. Changing one without proper design and testing can remove protection and create a fire risk.
Can one faulty appliance trip the whole home?
Yes, depending on the fault and protective arrangement. Stop using the suspected appliance and have the problem assessed.
