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, as an energy consultant (EFK) or energy expert (EuP), give advice and a layperson completely messes it up afterward, you could indeed face legal issues... if there are witnesses that you gave advice, you might end up with serious trouble. I would classify that as a myth or legend. Considering how many energy consultants explain things to laypeople on YouTube, the public prosecutorâs office would have to be very busy.
By the way, knowledge is not a secret. Do I now have to show my master or journeyman certificate at every professional conversation to avoid accidentally revealing trade secrets to a non-professional?

PS:
By the way, almost no layperson dares to work on gas lines. Why is that? 😉 Because:
- Gas is such a special case that there is hardly any reason for a layperson to work on it. Gas is supplied from the provider into the house and usually runs via a very short pipe to the boiler.
- You cannot connect outlets to gas lines.
- You cannot connect lights to gas lines.
- I donât extend gas pipes inside walls.
- I donât run gas lines for the electric vehicle charging station (wallbox) in the garage.
- You cannot connect devices like Shelly to gas lines (P.S. it is also legally not allowed to install Shellys yourself).
- Gas lines are not compatible with KNX systems.
and so on.
There are simply almost no use cases for laypeople, so there is no demand and hardly any explanations or videos online.
Electricity and water are topics that are explained thousands of times over.
