What documentation is required for the commissioning of the electrical installation?

Ok. Thanks. We have now been living in the house for almost a year and I am still waiting for the documents as well as the labeling of the fuse box. (I have since taken care of it myself)...

Without applying pressure, nothing at all will come even in the next 10 years.

Does something have to be handed over there?

No.

Or is it mandatory to create documentation?

For your own records, yes. For you: no.

Operator of the electrical system

As the owner of a single-family house, you are not the operator of an electrical system! … Even if your house has an electrical cabinet with fuses.

That means I do not have the right to a transcript? That can't be correct??

If the homeowner is not supposed to be the operator, then who is the operator?

But I still have the right to see that the electrical system has been properly checked, don't I?! Strange topic.

Even if nothing was agreed upon in the contract, you are entitled to a test report according to DIN-VDE 0100-600, as already wrote above. In my opinion, however, there are no legal regulations regarding the minimum scope of documentation. Try googling "documentation of electrical installations" or check elektropraktiker de, if I remember correctly, there was a page about it.
