ServiceInstallation & planning
Electrical planning by Kara Elektrotechnik, your electrician in Neuss, defines before construction begins where cables, sockets, lights, distribution boards and protective devices go and how the installation can be extended later. We advise and plan for new builds, conversions and renovations, for homes and businesses, in line with the DIN 18015 series and the VDE regulations.
Electrical planning describes a building's entire electrical installation before the first cable is laid. It covers the power supply from the house connection via the meter cabinet to the sub-distribution boards, the division of circuits, the sockets, switches and light points in every room, the protective devices and communication and network connections. Where required, building automation, solar PV, a wallbox and a heat pump are added.
The result is floor plans showing every outlet, an overview of circuits and distribution boards and a materials list. These documents are the basis for a reliable quote and for coordination with the architect, the heating and plumbing installer and the other trades.
Spare capacity is an important part of any plan. Free spaces in the sub-distribution board, a conduit from the plant room to the roof for a future solar PV system, one to the garage for a wallbox and one to where a heat pump will stand cost little at the shell stage. Added later, the same routes often mean opened-up walls and ceilings.
For residential buildings, the DIN 18015 series is the central planning basis. According to the description by DIN Media, Part 1 applies to the planning of electrical installations in residential buildings including power installations, communication, broadcast and lightning protection systems, and is also relevant for residential buildings with partial commercial use and for installations with building system technology. The table shows the three parts:
| Part | Content | Current edition |
|---|---|---|
| DIN 18015-1 | Planning principles | 2020-05 |
| DIN 18015-2 | Nature and extent of minimum equipment | 2021-10 |
| DIN 18015-3 | Wiring and disposition of electrical equipment | 2016-09 |
Part 2 sets out the minimum equipment a dwelling should have (DIN). Minimum equipment does not mean it is enough for every household, however: anyone who works from home, spends a lot of time in the kitchen or plans a wallbox later often needs more circuits and connections. That is exactly what we clarify during the consultation.
Concealed cables may not run anywhere through a wall; they are routed in defined installation zones. According to DIN Media, DIN 18015-3 covers the concealed installation of electrical cables and the arrangement of connections, switches and sockets. The aim is to reduce the risk of cables being damaged when gas, water or heating pipes are installed or during later work on walls, ceilings and floors.
This has a practical benefit for you: anyone who later puts up a shelf or chases a wall can estimate where cables run. The 2016 edition also defined installation zones for outdoor areas. We keep to the zones in our planning and document deviations, which may be needed for lightweight partition walls, for example.
Good electrical planning begins with questions about use, not with standards. Only once it is clear how the rooms will be used and what will be added in the coming years can circuits, connections and spare capacity be defined sensibly. We discuss these points in the first meeting:
The answers lead to a first draft, which we go through with you on the floor plan and adjust before detailed planning follows.
In offices, practices, shops and workshops other questions come first: three-phase connections for machines, workstations with power and network, lighting that suits the work, and a distribution system that can grow with the business. Where controls or larger distribution boards are needed, we plan the control cabinet construction at the same time.
For installations in commercial use, later operation also belongs in the plan, for example how installations and equipment will be tested at regular intervals. A clear distribution layout and complete documentation make these tests much easier; we describe how they work on our electrical testing page.
The plan is the template for the installation. Under § 13 of the German Low Voltage Connection Ordinance, the installation may only be built, extended or modified by the grid operator or a company registered in an installer directory. If we take on both planning and the electrical installation, both are in one hand, and changes during construction go straight into the plans.
On completion you receive the updated plans with the actual cable routes, the circuit list for the distribution boards and the test report. You will need these documents later for every extension, test or fault-finding.
As an electrician in Neuss we plan electrical installations for new builds in Allerheiligen and Rosellerheide as well as conversions in Grimlinghausen, Erfttal and Derikum. Outside Neuss we advise and plan for builders and businesses in Kaarst, Meerbusch, Dormagen, Grevenbroich and Korschenbroich as well as in Düsseldorf, Duisburg and Cologne.
For a first meeting, a floor plan, the type of project and an idea of which technology is to go into the building now and later are enough.
You can find every place we work in on our service area page.
Yes, at least in a simple form. Without a plan, the position and number of connections are decided on the building site, and later wishes such as a wallbox or solar PV cost more to retrofit.
As soon as the floor plan is settled and before the shell is complete. Cable routes, conduits and space for distribution boards can then be included without extra effort.
DIN standards are recognised rules of technology and are used in practice as the benchmark for professional planning. Whether they are contractually agreed is set out in the building contract.
Yes. In existing buildings, planning starts with an inspection of the current installation; this shows what can continue to be used and what will be renewed.
Yes, consulting and planning can also be commissioned separately. Having planning and installation from one source does, however, simplify coordination during construction.
It depends on the size and type of the building and the scope of the planning. After the first meeting you receive a quote.
