    I am currently reviewing the connection conditions issued by Tauron for one of the investments (reconstruction of a single-family house) and one issue attracted my attention. The ordered power is to be 20 kW, while the main security for the building located in the cable connector is to be 3x24 A.
    Is there something wrong here?

    It seems that it should be exactly as you say, but the conditions I pasted say something different, because they are supposed to be for 20 kW of power, and yet the protection included in the conditions cuts this power, and that is why I was surprised by these records.

    It is very possible that it is a fuse standard. 32A is 22,080kW.
    Do you lack power? 17.2 kW is not enough?
    It is a single-family house. That's only 2.75 kW of difference spread over 3 phases.
    In a single-family house, the total power taken from the network is averaged.
    For a short time, with 25 A, you can pull up to 30 A from each phase.
    It will not be possible to squeeze even 17.2 kW in a single-family house.
    It is important that the pre-meter is not S303 25 A but 3x 25 A.
    Preferably 3 power limiters of 25 A each.

    It doesn't matter if he uses all his power or not.
    Let ZE then charge a connection fee for 17kW and not for 20kW.
    You have to go to the ZE which issued the conditions and explain it.

    This requires writing and walking.
    What is the amount? Does it make sense to jerk off?

    Don't bother, just go ahead and sort it out. Maybe a phone call is enough. If he paid for 20kW, why should he be aggrieved? You have to fight for yours!
    I suspect that someone made a mistake and typed 25A out of habit

    Of course, there is a card in Tauron and it explains for what power and security.

    Of course, here's 32A. And this is not a fad because it affects the selectivity of the entire security system.

    It does not affect at all, even worsens, and the nominal value of the circuit breaker does not matter. There should be a power limiter or a selective switch. If I were the author, I would use a power limiter. It takes up the same space as an ordinary miniature circuit breaker, it even looks the same.

    But the Tauron writes nicely under the conditions that it is supposed to be a power limiter.

    I refer to what I read in the author's appendix.

    In my humble opinion, the obvious mistake of writing the terms. For 20kW it should be 32A.

    For the sake of accuracy, not in the cable connector but in the pre-meter in the connection-measuring cabinet.

    Because conditions are not written, only copied and pasted ... :D

    Just copying and pasting it is a pity that you do not read what you printed earlier. Then it goes to the supervisor for a signature who probably signs it "on the go" and such flowers come out. For me, at 21kW, there are already 40A security.

    This is still a small beer and can be quickly cleared up in ZE right away. Worse if the designer pats (read copy paste) a standard design and makes a mistake.
    I do not even mention the surveyors ;)

    And whoever has never committed a sin, let control + V throw an escort or even a capsule first ... :D

    And on the subject - it is enough to note in Tauron that the edit after pasting is unfinished. And it is gonna be fine... ;)

    Zbychu, a long time ago, years ago, descriptions for projects were written by hand and the typist typed them out on a typewriter. There were no errors then. Today, designers (I am writing about my plot) edit old descriptions called ancestors and I often encounter strange sentences in descriptions about other investments and objects. Oh, change. But is it good?

    Well, a symbol of our time. You can do something faster and easier, but also make a mean babola.

Topic summary

The discussion revolves around the discrepancy between the ordered power of 20 kW for a single-family house and the main security of 3x25 A, which limits the power to approximately 17.25 kW. Participants highlight that the power supply conditions issued by Tauron may contain an error, as the security rating should correspond to the contracted capacity. Suggestions include contacting Tauron for clarification and possibly adjusting the ordered power to align with the security rating. The conversation also touches on the importance of using appropriate power limiters and the potential for miscommunication in documentation processes.
