Good morning everyone,
I have another question. In our new build, the LAN cables are being installed in protective conduits. However, there is some disagreement about the required diameter according to the relevant standards. I have read about 25mm (1 inch) conduits.
According to the electrician, a 20mm (¾ inch) conduit should be used for simplex cables up to the outlet. No pull cord or similar is planned.
This naturally raises the question for me of how a future replacement would be possible... if it is even necessary.
What size conduits would you use? Where might it make sense to install an empty conduit for future use?
Thanks everyone

I recently had a huge thread on this topic, in case you want to dig it up.
In the end, we installed 25mm (1 inch) conduit. Whether you can replace it afterward is quite questionable anyway, depending on the bends they need to make inside your house. But in our case, the angles didn’t look as bad as initially expected.
One idea would be to connect the old (damaged) cable to the new one, and then pull the new cable through while removing the old one. That should possibly work. Normally, the cables shouldn’t get damaged either.

Most flush-mounted boxes (the plastic parts embedded in the wall into which the actual outlets, etc., are installed, such as those from Kaiser) have inlets for conduits or protective tubes of 20 and 25 mm (about 0.8 and 1 inch). The electrician shouldn’t make a fuss and just buy a bundle of 25 mm (1 inch) conduit.

The electrician should install what you want. I read DN25. Where is the additional cost? 10 cents per meter?With his excellent general contractor electrician, it will certainly be significantly more.S

I always determine individually how the cable fits through the conduit...
