ServiceSafety & testing
The emergency electrician service of Kara Elektrotechnik is available around the clock in Neuss and the surrounding area, including nights, weekends and public holidays. Call us if the power is out in the house, a fuse keeps tripping, there is a smell of burnt plastic or water has reached electrical cables. We come as quickly as the situation allows.

It is an electrical emergency when the installation poses an immediate danger or important parts of the building are without power and cannot be switched back on. Typical signs are a burning smell, smoke or sparks at a socket, switch or distribution board. If water has reached cables, sockets or the meter cabinet, for example after a burst pipe or heavy rain, the affected area should stay without power until an electrician has checked it.
It is also an emergency if the power is out in the whole house or part of the building and the residual current device (RCD) or fuse cannot be switched back on. For businesses there is also everything that depends on power: fridges, heating, servers or machines whose failure quickly causes further damage.
If there is smoke or an open fire, call the fire brigade on 112 first.
Many faults can be narrowed down by how the installation behaves before an electrician arrives. The table helps with a first assessment:
| What you notice | Common cause | What to do |
|---|---|---|
| No power in the whole house, neighbours too | Fault in the public grid | Call the local grid operator's fault line |
| No power in the whole house, neighbours have power | Tripped RCD or a fault at the main fuse or house connection | Check the fuse box; if it stays dark, call the emergency service |
| RCD trips again immediately | Insulation fault, moisture or a faulty appliance | Unplug all appliances in the area and switch the RCD on once; if it keeps tripping, call us |
| Fuse trips with one particular appliance | Overload or faulty appliance | Stop using the appliance |
| Warm socket, burning smell | Loose terminal or overload | Switch the circuit off and call the emergency service |
The table does not replace fault finding, but it helps when you call: if you can tell us whether your neighbours have power and which switch has tripped, we can assess the situation better before we set off.
Until we arrive you can narrow the situation down with a few safe steps, without opening the installation yourself.
Please do not open covers, sockets or the meter cabinet yourself. Under § 13 of the German Low Voltage Connection Ordinance, work on the electrical installation may only be carried out by the grid operator or a company registered in an installer directory.
Most power failures in a house have a cause that can be narrowed down. If the RCD trips, there is often an appliance with an insulation fault behind it: a kettle, washing machine, dishwasher or an outdoor light that moisture has got into. If the RCD can be switched back on once all plugs are pulled, the fault is usually in one of the appliances and not in the fixed installation.
If a single fuse trips instead, the circuit is often overloaded, for example when a fan heater, kettle and microwave are on the same line. In older houses, loose terminals in sockets and junction boxes add to this. They heat up under load, which shows as warm covers, flickering light or a burning smell. This is not a case for calling tomorrow, because a loose contact can develop into a fire.
If the whole house is without power and the neighbours are too, the fault is in the public grid. Then the local grid operator is responsible, not the electrician.
An emergency call-out has two goals: first remove the danger, then fix the cause. Already on the phone we ask what happened and tell you what you can do until we arrive.
On site we measure the affected circuit and check the distribution board and protective devices. Faulty circuits are switched off so there is no more danger and the rest of the house has power again. Where possible we repair immediately. If parts are needed, we make the installation safe with a temporary solution and arrange an appointment for the final repair.
After major damage, for example from water or fire, a complete electrical test with a test report makes sense afterwards. What the call-out costs depends on the time of day, the work and the materials; we discuss it with you directly.

Yes, once. If it trips again immediately there is a fault; the circuit then stays off until an electrician has checked it.
The local grid operator. If your neighbours have no power either, the fault is usually in the public grid, not in your installation.
Switch off the affected circuit or the RCD, do not touch anything and call the emergency service. If there is smoke or fire, call the fire brigade on 112 first.
