Surge protection for every new building

From now on, new standards prescribe mandatory surge protection for standardised electrical installations

It's official: In every new building to receive a standardised electrical installation ‒ surge protection is a must. The revised standards DIN VDE 0100-443 and DIN VDE 0100-534 have been in force since 1 October 2016 and specify where, when and how each type of surge protection is to be installed.

In industry and commerce, public buildings, hospitals and other facilities, protection devices were already prescribed for a standardised electrical installation. What's new is the obligation to plan surge protection in all new houses and purpose-built buildings.

In concrete terms, this affects areas in which "groups of people" are to be expected ‒ for example, large housing blocks, offices, schools or churches. In addition, the standard DIN VDE 0100-443 names areas used by "individual people" ‒ such as housing and small offices, if, in these buildings, resources of surge voltage category I or II are installed.

Resources of surge voltage category I and II are, for example, buildings and heating controllers, telephone systems or roller shutter controllers. Also, electronic devices, such as computers or sensitive kitchen appliances are endangered by surge voltages and are used on a daily basis in almost every household. Suitable surge protection provides increased safety for these devices and also prevents arcing and the resulting fires in buildings.
