Whether in sampling at the prefabricated house manufacturer or in individual planning with a trusted electrician – the experts know exactly how the electrical installation is done. But as the building owner, you should also consider which type of installation you want, which equipment makes sense – and how much of it. The following dozen tips will help you make the right decisions.
1. How many connections does the perfect electrical installation need?
When planning, it is determined how many secured circuits, individually switchable lighting circuits and how many sockets are to be installed. The various standards of the Electro + Initiative provide an indication of the need and the costs for this. But when in doubt, every household has different requirements, such as a study with a computer and several peripheral devices, a high-quality hi-fi system in the living room, or a home cinema in the basement. Provide your own fuses for extra applications in these rooms and plan enough sockets.

2. Switch design
The eye switches on – an important part of the sampling, therefore, relates to the design of the buttons and socket frames. The variety continues to grow, for example with flush design switch ranges. The more complex and chic the models, the higher not only the price of the switches and covers increases. Installation is also becoming more and more complex.
3. Smart home or not?
You can gradually make the decision to use smart home technology. But in the new building, the electrical installation should be smart home-ready. This means: The light switch is replaced by two devices: An actuator installed centrally in the control cabinet that closes the circuit for each luminaire and buttons that control the respective actuator. The switching or dimming actuators can be freely programmed on each button, which then controls one or more consumers. This installation is available in different versions. With KNX bus technology, it is significantly more expensive than the classic variant – but hardly with Enocean radio technology.
4. Plan TV reception
Antenna cables for TV reception are also laid along with the electrical installation. In this context, clarify how you want to receive your television program – satellite gives you the greatest free choice of channels, cable reception saves you having to install a dish on the roof, and with Internet television such as Telekom Entertain TV, the network connection for television is sufficient. In order to be flexible in the long term, it is definitely advisable to move an antenna and a network connection into the living room and all other rooms with TV reception.

5. Central distribution
Telephone, DSL connection, network, TV reception – the media technology in the house is becoming more and more diverse and changes frequently, for example when you switch the DSL connection from the Telekom to the cable provider.
With a central media distribution point in the technical room, you remain flexible. This is where the cables and data for TV and telephone arrive, are processed in the respective router, and then forwarded in a star shape.
