5-pin cable to 3-pin cable

If you give tips as an EFK or EuP and the layperson then completely messes it up, you are, by the way, criminally in focus... if there are witnesses that you gave advice, you might end up with a massive problem.

I would place that in the realm of legends and myths. When I see how many EFKs explain things for laypeople on YouTube, the public prosecutor’s office should be all over that as well. By the way, knowledge is not a secret. Do I now have to show my master’s or journeyman’s certificate at every technical discussion so I don’t accidentally reveal guild secrets to a muggle?

PS: By the way, almost no layperson dares to deal with gas lines. But why? ;)

Because: - Gas is such a special case that there is almost no reason for a layperson to handle it. Gas comes from the supplier into the house and from there usually with a very short line to the boiler - I can't connect sockets to gas - I can't connect lamps to gas - I don't extend gas lines in the wall - I don't lay gas for the wallbox in the garage - I can't connect Shelly etc. to gas lines (P.S. legally, Shellys are also not allowed to be installed by oneself) - Gas lines are not KNX-capable and so on. There are simply almost no use cases for laypeople, therefore no demand and certainly almost no explanations/videos on the internet. Electricity and water are things that have been explained thousands of times.
