Electrical planning - How many sockets are enough?

The answers read typically again... like: let us botch it until the end then you won't see anything of it anymore

Yes, the cleaner does that nicely.

Are there electrical cables in the corrugated pipes? Why exactly? There are cables that need to be protected and cannot lie directly, with the requirement to be able to pull new cables in. I can't imagine that corrugated pipes are allowed to be crushed. That contradicts the purpose of the pipe. It's also a pity that the electrician doesn't even show a willingness to perhaps look at this critically together. Therefore, I would get someone who can officially assess this. Maybe your acquaintance can also put that in writing. Don't let the schedule stress you now. Better accept delays and have it done properly.

Hi, I'm currently at the construction site, the electrician, to be precise, the journeyman just said that everything is fine, the cable in the corrugated tube (satellite cable) is not pinched. He also said he can gladly pull the nails out a bit. The only problem is that the sturdy tube remains pinched and doesn’t "inflate" again. He also said that they will measure it at the end. And over such a long distance, you can’t really pull the cable any further anyway.

Yes, they still do not work according to DIN even though they refer to it. Media cables, i.e. SAT, telephone, LAN, must be installed replaceably in protective conduits regardless of the length of the line.

Nail clips through the conduit also indicate "quality" at its best.

He is right that power cables for the roller shutter motors are no longer replaced, and NYY cables may also be compressed.

But the rest is nonsense...

Phew, I wouldn’t dare to write such blunt emails, you want to maintain at least a decent relationship and somewhat motivated craftsmen - but maybe otherwise you won’t be taken seriously.

I think everything will probably work out, but clean work would look different to me and I would have wanted some of the cables replaced again. Especially when it comes to data cables, most electricians don’t really have a sense of how sensitive they are. Better to do it yourself if you have the chance - and can do it better yourself.
