Electrical installation by a friend - Mandatory inspection due to insurance?

[...] Electrician who inspects the system and creates a test report. But be careful that the report doesn’t burn up in case of fire

You can deposit it at the district court *LOL*

And since he's probably doing it for a case of beer, without a written contract, he will never have been at your place in case of damage. Prove otherwise...

It's a gray area. After all, you're not doing it yourself, but getting someone who can do it. If he works in the industry, maybe he can borrow a VDE tester? Just make the necessary measurements, done.

If you want it legally secure, a master craftsman company must measure, document, and sign it. That of course costs.

A good friend of mine is a trained electrician and works as an industrial electrician.

See NAV § 13 regarding installations.

The question that arises for me is whether this can cause problems with the insurance because I then do not have an invoice etc. for the work.

In the event of property damage or even personal injury, it primarily depends on whether the recognized rules of technology (= minimum standard) were observed and, if the work complies with the standard, less on the qualification of the person executing it and whether they have an entry with a VNB, which your friend obviously cannot show.

Do I then have to have the installation accepted by another electrician afterwards?

Electricians with an entry in a VNB also do not perform sovereign tasks like structural engineers or district chimney sweeps, which is why the electrician with a concession does not "accept" the combined work of a layperson and an industrial electrician. However, as the client, you accept their service as an inspection.

I can't really imagine that any electrician would put up with that.

Quick "acceptances at a fair price" are a separate business field. In such quick checks or telepathic "remote acceptances," it is usually ignored that the registering electrician is not allowed to cover third-party services with his name.

I will check - thanks. Assuming there is nothing mentioned about it, can I then conclude that nothing special is required?

Insurance distinguishes between intent and negligence. They will certainly not demand old invoices that may have been destroyed by fire, but rather bear the burden of proof. For that, there are experts. Your problem does not exist as described, because private individuals are also allowed to issue invoices. And there is also the law of neighborhood assistance. However, of course, one can have the electrical work professionally inspected in a completely lawful manner if one believes that the professional is not working according to DIN standards.

With a layperson in electrical engineering, it is generally assumed that they cannot perform the work properly due to lack of training... anything else would be completely absurd.

Neighborly help, yes. But which electrician is so stupid that he admits to having connected the sub-distribution in this way after a fire? I would like to shake that person's hand, honestly.
If he actually admits it and the fire originated there, he is liable in civil court for damages. Companies are often insured against such mistakes, private individuals rarely...

But ultimately. Don’t trust your buddy? Then have a company do it.

Neighborhood help, yes. But which electrician is so stupid that he admits to having connected the sub-distribution in this frame after a fire? I would like to shake his hand, honestly. Does he really admit that

That's good! That is not asked at all afterwards. Intent or negligence. In the latter case, payment is made, because it is also only a technical defect.
