Tilslutningskontrol: Periodically check the tightness of the terminal screws. Loose connections can lead to overheating and potential hazards.
Funktionstest: If safe to do so and in accordance with local regulations, occasionally test the trip mechanism by simulating an overload or short circuit (only by qualified personnel).

IMPORTANT: Any maintenance requiring internal access or complex repairs must be performed by qualified personnel only.

8. Fejlfinding

If the circuit breaker trips or fails to operate correctly, follow these steps:

Breaker Trips (Green Indicator Visible):
- Identificér årsag: A tripped breaker indicates an overload or short circuit. Disconnect all appliances or devices connected to the affected circuit.
- Nulstil: After identifying and resolving the cause (e.g., unplugging a faulty appliance, fixing a short), push the operating handle fully down to the "O-OFF" position, then push it up to the "I-ON" position.
- Vedvarende tripping: If the breaker trips immediately after resetting, do not attempt to reset it again. There may be a serious electrical fault. Contact a qualified electrician.
Afbryderen nulstilles ikke:
- Ensure the handle is pushed fully to the "O-OFF" position before attempting to push it to "I-ON".
- If it still does not reset, there might be an internal fault with the breaker or a severe electrical issue. Do not force the handle. Contact a qualified electrician.
Overophedning:
- If the circuit breaker or surrounding wiring feels hot, immediately disconnect power at the main supply.
- Check for loose connections, overloaded circuits, or damaged wiring. Contact a qualified electrician.
