ᐅ Electrical Installation for a New Single-Family Home – Assessment and Suggestions

I have optimized this with a friend for now. It is not yet finalized.
The cables are very easy to pull through.
Attached are also a few pictures showing that the cables do not reach all the way into the electrical boxes. You don’t really need to understand why...

I suspect the cables

They probably fit neatly at first, but were then pushed back by other cables.

And if something doesn’t work after all (such as data lines), the electrician is off the hook.

230v counts as high voltage.

According to DIN and in everyday language, yes—but according to VDE standards, not for 20 years now.

We only did this on the condition that we take no responsibility if something doesn’t work and that the electrician retains full warranty liability. He will inspect it afterwards, and that’s that. I’m not stupid.
We did not touch the electrical wiring. It has been like that from the beginning. The sheath of the cable must extend all the way into the junction box. This is mandatory according to construction supervision because gypsum plaster is corrosive. So we sealed everything with Rotband to protect those areas. He simply stripped too much insulation. That’s shoddy workmanship. Plain and simple.

We didn’t touch the power cables—they were like that from the start. The cable sheath has to go all the way into the junction box. This is mandatory according to the site supervisor because the plaster is corrosive. So, we sealed everything with joint compound to protect those areas. He simply stripped too much insulation off. That’s poor workmanship. Plain and simple.

From what I know, the cables basically just hang out of the box or are coiled inside it (not stripped yet) and are only stripped inside the box after the shell construction phase using a tool like "JOKARI XL". That way, something like this can’t happen.
At least, that was the recommendation from our electrician (we’re doing it ourselves).

That’s also how I know it.
Alternatively, you strip the cable and then run the wiring from the box to the distribution board or switch. That way, problems like this can be avoided.
In the end, it’s just sad that the work isn’t done properly and conscientiously. The time pressure is enormous and they have to cut costs everywhere. He was working alone and slowly installed everything over three weeks. That means he’s probably working on other houses at the same time. I find that crazy. Doing one project at a time would make much more sense. But if the boss wants it that way, there’s no choice.
You pay so much money and trust professional companies, yet you still have to check everything yourself, read up on it, and sometimes even complain. It’s just terrible.

So you protect with gypsum plaster (= Rotband) against the plasterer's gypsum plaster? Works 😀
