When part of your home, holiday rental, or hotel room suddenly goes dark, a tripped circuit breaker is usually the cause — and it is something any adult can fix in under five minutes without calling an electrician. The video above shows the process clearly; the steps below walk you through it in order so you know exactly what to do and, just as importantly, when to stop and call a professional. Whether you manage a villa in Crete or an apartment in Athens, keeping this guide bookmarked means power outages never catch you off guard.
What Is a Circuit Breaker and Why Does It Trip?
A circuit breaker is a safety switch inside your electrical panel (the metal box usually mounted in a utility room, hallway, or meter cupboard). Its job is to cut power the moment a circuit draws more current than it can safely handle — protecting the wiring inside your walls from overheating and potentially catching fire.
Breakers trip for three main reasons: an overloaded circuit (too many appliances running at once), a short circuit (a live wire touching a neutral or ground wire), or a ground fault (current leaking to an unintended path). Identifying which cause applies to your situation determines whether a simple reset is enough or whether you need an electrician.
How to Tell a Breaker Has Tripped
Open your electrical panel and look at the row of switches. A tripped breaker sits in a middle or 'half-off' position — it has moved away from the ON side but has not clicked fully to OFF. Some panels use a small red or orange indicator window that appears when the breaker trips, making identification even easier. Greek panels (which commonly use DIN-rail breakers from brands such as Hager, ABB, or Schneider) typically show the lever shifted to a visually obvious mid-position.
If every breaker looks fully on but you still have no power, the problem may be with the utility supply rather than your own panel — in that case, check DEI's outage map or call 10500 before touching anything.
How to Reset a Tripped Circuit Breaker: 5 Steps
- 1
Switch off or unplug devices on the affected circuit
Before touching the panel, go to the room that lost power and turn off light switches and unplug all appliances. This removes the load from the circuit and prevents a second trip the moment you restore power — which is the most common reason a reset appears to fail.
- 2
Locate your electrical panel and identify the tripped breaker
Open the panel cover (no tools needed; it lifts or swings open). Scan the rows of breakers for the one sitting in the middle position or showing a red indicator. Most panels have a label chart on the inside of the door — if yours does not, make a note to label circuits once power is restored, which makes future fault-finding much faster.
- 3
Push the breaker firmly to the full OFF position
Before flipping it back on, you must first push it completely to OFF. Breakers are mechanically latched when tripped and must be reset from this fully-off position. Skipping this step and pushing directly to ON is the single most common mistake — the lever will feel stiff and will not hold.
- 4
Flip the breaker decisively to ON
With one firm motion, push the lever to the ON side until you feel or hear a click. Avoid a slow or hesitant movement. If the breaker holds, the panel light (if present) will go out and you will hear appliances in the affected room hum back to life.
- 5
Reconnect devices one at a time and observe
Return to the room and plug devices back in one by one, leaving a minute between each. If the breaker holds with all devices reconnected, you had an overload — consider redistributing appliances to other circuits. If the breaker trips again immediately upon reconnection of a specific device, that appliance likely has a fault and should be inspected before further use.

FAQ
- What should I do if the breaker will not stay on after I reset it?
- A breaker that trips immediately or within seconds of being reset — even with no load on the circuit — indicates a short circuit, a ground fault, or a failing breaker. Do not keep resetting it. Disconnect everything on that circuit and call a licensed electrician. Repeated forced resets can damage the breaker's thermal mechanism and create a fire risk.
- Can a tripped breaker cause damage to my appliances?
- The trip itself is a protective action, so appliances are generally unharmed. However, a sudden loss of power during operation can corrupt data on computers or smart TVs, and compressor-based appliances such as air conditioning units and refrigerators should be given a 3-5 minute wait before being switched back on after power is restored, to allow the system pressure to equalise.
- How many times can I safely reset the same breaker?
- A healthy breaker can be reset many thousands of times over its lifespan. But if you find yourself resetting the same breaker repeatedly — more than once in a short period — that is a sign the circuit is consistently overloaded or there is an underlying wiring fault. In a rental property or hotel, this situation needs a qualified electrician to assess the circuit capacity before guests are affected again.
