Breaker Keeps Tripping? Causes & Fixes in Luxembourg
Why Your Breaker Keeps Tripping
If a breaker in your Luxembourg home trips again and again, it's doing its job — protecting you from a real problem. Here's what's actually happening.
The 4 Real Causes
1. Circuit overload Too many appliances on one line. Common in older Luxembourg apartments where one circuit feeds the whole kitchen.
2. Short circuit A live wire touches a neutral wire. Usually trips instantly with a loud snap. Often caused by a damaged appliance cable or a nail in the wall.
3. Ground fault Live wire touches a grounded surface — common in bathrooms and kitchens where moisture gets in. Your differential breaker (30mA) catches this.
4. Faulty breaker After 15–20 years, breakers wear out and trip on normal loads. Very common in panels installed before 2005.
Safe Things to Try
- Unplug everything on that circuit
- Reset the breaker once
- Plug appliances back in one by one
- The one that causes the trip is the culprit
Stop and Call When
- The breaker trips with nothing plugged in → wiring fault
