What to Do in Case of a Short Circuit at Home (Luxembourg)
A Short Circuit Just Happened — Now What?
A short circuit ("court-circuit") is when a live wire touches a neutral or ground wire. Your breaker trips instantly with a loud snap. Here's the safe response sequence.
Step 1: Stay Calm, Don't Panic-Reset
A breaker that tripped did its job. Do not keep flipping it back on — repeated resets through a short circuit can start a fire.
Step 2: Identify What Was Running
Whatever you just plugged in or switched on is likely the cause:
- A space heater, kettle, or hairdryer
- A lamp with a damaged cord
- A wet appliance in the bathroom or kitchen
- An extension cord with too many devices
Step 3: Unplug Everything on the Affected Circuit
Then try the breaker reset once. If it holds, plug things back in one by one. The one that trips it again is the culprit — throw it out or have it repaired.
Step 4: Stop and Call If
- Breaker trips again with nothing plugged in
- You smell burning or see smoke
- Outlets or switches are warm or discoloured
- Multiple circuits are affected

Frequently Asked Questions
Is a short circuit dangerous?
Yes — a short circuit can start a fire if not properly cut by a breaker. Modern Luxembourg installations have 30mA differential breakers that protect you, but old panels (pre-2000) may not react fast enough.
Can I reset a breaker after a short circuit?
Once — yes, after unplugging the appliance that caused it. If the breaker trips again immediately, stop and call an electrician. Repeated resets can damage wiring or start a fire.
What causes a short circuit at home?
Damaged appliance cords, water in outlets, faulty wiring inside walls, or overloaded extension cords. In older Luxembourg buildings, deteriorated insulation is the most common cause.
