I have a concrete garage from Zapf, where the electrical cables are embedded in conduit within the concrete. The embedded cables consist of 3 x 1.5 mm² (1.5 sq mm) wires. The supply line to the garage, which is routed through the floor, is made as NYY 5 x 1.5 mm² (1.5 sq mm). The five conductors have the colors yellow/green, blue, black, gray, and brown. Which three conductors from the 5-core cable should I connect to the three conductors in the garage? Yellow/green for grounding is clear to me, but which two other colors from the 5-core cable should I use? Good luck Raiweired

If you’re giving advice to non-professionals, you should at least mention that the two "remaining" phases need to be properly insulated. Simply cutting them off is not enough, and wrapping them with tape isn’t sufficient either. Otherwise, someone might eventually lie next to the cable in the garage and not get up again... especially since children like to play and touch everything.
So, please advise laypersons not to tamper with this, but to hire someone who is qualified... and, above all, authorized. I thought that was clear. He just wanted to use an existing cable without necessarily terminating all poles in the distribution panel. I also recommended consulting an electrician.

I also recommended consulting an electrician. No. If you already point out that "green-yellow" is the grounding conductor, you apparently assume he has no knowledge at all.
Therefore, it’s best to advise a layperson exclusively to hire a professional and not give any tips. That way, you are also legally safe in the end.

For non-experts, always recommend hiring a professional and avoid giving any tips. This way, you are also legally safe in the end. A nice piece of advice. But unfortunately far from everyday reality.
Then you would also have to hire an electrician to change a light bulb – who is just as likely to show up as for connecting the cable from the original poster. Meaning, usually not at all...

Then you would also need to hire an electrician to change a light bulb – and they would be just as eager to come as to connect the cable mentioned by the original poster. In other words, usually not at all... No. Even a non-professional is allowed to change a light bulb, up to 200W and 250V rated voltage.
By the way, if you give advice as a qualified electrician (EFK) or electrical professional (EuP) and a layperson follows it and gets seriously injured or worse, you can face legal consequences… if there are witnesses confirming that you gave the advice, you could be in serious trouble.

SaniererNRW12320 Sep 2022 10:54I am aware that according to NAV only a registered installation company is allowed to work on cables.
However, this advice is far from practical in real life. At least in this case.

Nevertheless, this advice is far from real life. At least in this case. In reality, people unfortunately still die because they perform electrical work for which they are not qualified.
And because professionals tell them what they need to do... usually adding that it’s not that difficult after all...
PS:
Almost no layperson dares to handle gas lines, by the way. Why is that? 😉
