ᐅ Electrical Installation by a Friend – Is an Inspection Mandatory for Insurance Purposes?

Hello everyone,
A good friend of mine is a certified electrician and works as an industrial electrician. Since we need a sub-distribution board in the garage, he offered that I could do the cable pulling and he would handle all the connections.
My only concern is whether this might cause problems with the insurance, as I would not have an invoice or documentation for the work done.
Would I then need to have the installation inspected and approved by another electrician afterward?
I can’t quite imagine that another electrician would take responsibility for that.
Best regards

None of this is illegal (in a single-family house). The criminal code is meant for other matters.
However, insurance companies can be difficult if there are faults in or caused by the electrical installation.
A professional electrical inspection is the proper way to protect yourself against this. Just inquire with a few companies. The effort involved in a proper electrical inspection should not be underestimated (access to every socket and terminal). Proper documentation beforehand helps a lot with this.

It’s the same as with water pipes.Even the practical electrician interprets NAV §13 as meaning that the registration requirement only applies up to the measuring devices. After that, a "regular" electrical specialist may take over.
But yes, the paragraph is probably (intentionally) worded in a way that allows for a different interpretation.

Everything inside the house has been approved. It was all done by the company contracted by the utility provider.
For us, it’s about additional work or anything outside and in the garage. Maybe I’ll actually find someone who can create a test certificate for that. I mean, no one will be able to verify later on any changes inside the main distribution board in the house anyway.

You should definitely avoid doing anything yourself on anything that is actually used as drinking water.
A garden irrigation system connected after a backflow preventer is more likely to be acceptable. However, I would need to look up the exact legal regulations first.
