Do you come to Heinsberg if the firm is in Gangelt?

Yes. Heinsberg and the surrounding places are part of the working area. Just give the address in your enquiry, as that helps to plan the visit properly.

The residual current device keeps tripping. What now?

That points to an earth leakage, often at a single appliance or a cable that has taken in moisture. We narrow the affected circuit down by measurement rather than swapping fuses.

Does the meter cabinet really have to be renewed?

Not in every case. The framework is set by the network operator technical connection rules, for instance when a wallbox or a heat pump is added. We look at what is there and tell you what is required.

Can we stay in the flat while the work is going on?

Usually yes. Working circuit by circuit keeps the kitchen and the heating off supply for as short a time as possible. What gets switched off, and when, is agreed beforehand.

Do I get documentation of the installation?

On request, yes. A board schedule and the measured values belong to a properly handed over installation and help anyone who works on it later.

What helps you make a first assessment?

A photograph of the open board, roughly what year the house was built, and a sentence or two about the problem. That already says a great deal before anyone sets off.

Circuit

Where the current belongs

An electrical installation is a chain. A fault shows itself at the socket, but it is usually solved further up the line. That is why we look at the whole run.

Supply in

Meter cabinet and service head

Meter position, main tails, the area ahead of the meter. This is where it is decided what the building can carry later and what can still be added.

Distribution

Distribution board and protection

Overcurrent protection, residual current protection, clean terminations and labelling that will still be true in ten years.

Final circuits

Rooms, light and sockets

From the cable in the plaster to the switch on the wall. Enough sockets, and in the places where they are actually needed.

Have the installation looked at

Terminal strip

Electrical work in Heinsberg

Eight terminals we work on most often. Your enquiry will almost always fit one of them.

Installation in a new build

Plan the cable routes, set the boxes, build the distribution board and commission the installation.

Older property and rewiring

Replace old cabling, renew the board, add residual current protection. Section by section, so the house stays liveable.

Meter cabinet and boards

Meter position to the network operator technical connection rules, distribution board built cleanly and labelled properly.

Fault finding and breakdowns

A breaker keeps tripping, the RCD lets go, the light flickers. We measure the circuit rather than guess at it.

Lighting and switching

Light points in the room, switch positions, dimmers, outside lighting and motion detectors.

Sockets and circuits

Extra sockets and dedicated circuits for a washing machine, a workshop, an office or a garden building.

Connecting appliances

Cookers and hobs, instantaneous water heaters, a heat pump or a wallbox connected properly to the installation.

Testing the installation

Measure, test, record. For landlords, buyers and anyone who needs the condition in writing.

Board

What sits behind the cover

Four views from the world behind the distribution board cover. They show what matters in an installation: order, labelling, and protective devices that trip when they have to.

Board from the front A complete panel with meter position, outgoing ways and labelling

Busbar and modules Phase busbar, surge protection, residual current device

Switch and socket Switch, dimmer and socket in one shared frame

Residual current device Two pole, with a test button for the regular functional check

How an enquiry becomes an appointment

Four points along the way. At every one of them you know where you stand.

M1

You describe the job

Through the form, on the phone or by email. A few sentences are enough to begin with.

M2

We look at the installation

On site, or from your description and photographs. Only then is it clear what is really needed.

M3

You receive a quotation

With individual items you can read through, rather than one sum with no explanation.

M4

Work and handover

Appointment, work, functional test. At the end you know which circuit goes where.
