The first thing to check is whether the power is out only in your place or across the whole building — that immediately splits the cause into either "the utility cut power" or "something's wrong inside your home." After that, check the panel: a tripped breaker or RCD is almost always visible from the switch's position.
Possible causes
- A breaker or RCD tripped at the panel — one circuit or the whole incoming feed shut off
- A scheduled or emergency power outage in the building or area from the utility company
- A break or damage in the wiring inside a wall on a specific section
- A fault in the main breaker, the meter, or loose terminals in your own panel
- A problem in the building's shared wiring — the riser or the building's main distribution unit, relevant for apartments
- Several bulbs burning out at once from a voltage spike — less common, but it happens
Why it matters
Losing power on its own isn't dangerous, but the cause behind it can be: if the power went out because of a short circuit or badly overheated wiring, repeatedly trying to reset the breaker without understanding why can lead to a fire. Caution is also needed around the panel itself — don't touch the meter, its seals, or the main terminals unless you're confident in what you're doing.
What to do
When you need an electrician
Call an electrician if the power is out only in your place, the breaker trips again as soon as you reset it, or the outage came with a burning smell, crackling, or sparks. If it's the utility's outage, an electrician can't fix that — check with your power supplier instead.
Frequently asked questions
Power is out in just one room but fine elsewhere — what does that mean?
It's most likely not the whole home but a single circuit — the breaker for that room has tripped, or there's wiring damage on that specific section. Check the panel: if one breaker is in the "off" position, try resetting it once.
Power flickers on and off with no obvious reason — is that dangerous?
That can point to a bad contact at the incoming feed, the meter, or the panel terminals, and that kind of contact tends to heat up over time. It's not the same as losing power entirely, but it's worth investigating — call an electrician for a diagnostic.
After the power came back, the breaker holds for a couple of minutes then trips again — why?
That usually points to an overload or a hidden short circuit that doesn't show up immediately. Don't keep resetting the breaker repeatedly — it needs a diagnostic to pin down the exact cause.
