Distance between the building and the power line - wall or roof?

In the conditions of the ZE, it was written that the distance of the building from the 15kV line is to be 5 meters from the horizontal projection of the extreme working conductor, and therefore I have a question - from what point to count - the walls of the building or the outline of the roof, and from what provision does this result?
The plot is so narrow that every meter is of great importance ...
My suggestion is that the distances from the boundaries of 3m or 4m are counted to the building wall and the roof extension does not matter here.
If anyone has any experience in this topic, please help.

I am curious where they took 5 meters from. A friend recently had the same problem and he got 3 meters, according to:

I don't know if ZE has the right to freely give this distance, because that's how we always play the lottery.

Maybe from the first article you linked yourself:

Regulation of the Minister of Infrastructure of February 6, 2003 on occupational health and safety during construction works (Journal of Laws No. 47, item 401) in § 55 (...) it is not allowed to locate workplaces, product storage sites and materials or construction machinery and equipment directly under overhead power lines or at a horizontal distance from the extreme wires, less than:
2. 5 m - for lines with a rated voltage above 1 kV but not exceeding 15 kV;

Why doesn't it matter? The roof is an integral part of the building. At your request, your architect can also design a roof extension covering, for example, a driveway or a swimming pool. And what? Do you want to have this roof right next to the 15kV line?

A slightly bizarre subject. In most threads, people ask how to get rid of the power line, how to wire it for free, how to simply throw it out of the plot as far as possible, how to condemn the money for its existence. For the first time I read that someone would like to "come closer".

Complementing the previous answers, I also recommend taking a look at the spatial development plan (if a given plot is included in it), because there are often specific requirements as to the distance of the building from individual installations / networks.

Are you aware that cables have a feature called sag? It is a change in the length of the wires depending on the temperature. Hence, some differences in the given distances may result. I don't know the local situation, so I don't know if I am interpreting it correctly.



This is a table of not very current regulations, but as far as I know these distances have remained unchanged.

From the norm. At the moment, I do not even know which one, because the European regulations for the construction of power lines have shredded our, once quite consistent standard PN-E-05100-1, and the network operator based on them creates its own company rules, which cannot contradict the European standard.
