A breaker that trips once is a non-event. A breaker that trips weekly is your electrical installation filing a report. Before you call anyone — or worse, learn to live with it — a few safe checks can tell you roughly what is wrong and make the electrician's visit shorter and cheaper.
Know which device is tripping
Open your distribution board and look at what moved:
- One small breaker (MCB) down — an overload or fault on that single circuit.
- The RCD (the wider switch, often with a "test" button) down — earth leakage somewhere: electricity escaping where it should not, often through moisture or a failing appliance. The RCD is doing exactly its job.
- Everything down including neighbours — a supply issue, not your installation.
The unplug-everything method
For RCD trips, this narrows the culprit safely in fifteen minutes:
- Switch off and unplug every appliance you can reach.
- Reset the RCD. If it holds, the wiring is likely fine and an appliance is the problem.
- Plug appliances back in one at a time, running each briefly.
- When the RCD drops again, you have found your suspect.
If the RCD will not hold even with everything unplugged, the fault is in the fixed installation — moisture in a junction box, a damaged cable, a failing socket. That is an electrician's job, and in Malta's humid months it is a common one.
Malta's usual culprits
- Water heaters. A scaled, blistered element leaks to earth as it fails. If trips happen when the geyser heats, there is your answer — see our water heater guide.
- Washing machines and dishwashers — heating elements again, plus water and vibration.
- Outdoor sockets, pumps and garden lighting after rain. Maltese winters find every badly sealed box; if trips follow the weather, tell the electrician exactly that.
What not to do
Do not hold the breaker on, tape it, or "upgrade" a breaker to a bigger one so it stops tripping — breakers are sized to protect the cable behind them, and oversizing turns a nuisance into a fire risk. Do not open fittings or boxes yourself while investigating; identification by unplugging is the safe limit of DIY here.
Calling it in
When you post the fault on Qabbad's electrician page, include: which device trips (photo of the board helps), how often, what you were running at the time, whether the unplug test pointed anywhere, and the property's rough age. Fault-finding is billed by time — arriving with that information can halve it. Typical diagnostic rates are in our electrician price guide.
Frequently asked questions
Why does my RCD trip when it rains in Malta?
Rain finds moisture paths in outdoor sockets, garden lighting, pumps and roof-level junction boxes. Water bridges live parts to earth, the RCD detects the leak and disconnects. An electrician traces the wet circuit and reseals or replaces it.
Is a tripping breaker dangerous?
The tripping itself is the safety system working. The underlying cause — a leaking appliance or damaged wiring — deserves prompt attention, and the truly dangerous move is defeating the breaker to stop it.
How much does electrical fault-finding cost in Malta?
Expect a call-out of €25 to €60 plus time on the fault, at roughly €25 to €45 per hour. Faults you have already narrowed down with the unplug method cost noticeably less to fix.
My whole street lost power — who do I call?
Supply interruptions are the distribution network's territory, not a private electrician's. If neighbours are dark too, report it to the utility and wait it out.
