Making slits (position during ceiling installation)

Hello, I want to make the slots for the electrical installation myself. I am familiar with the installation zones for this. Normally, horizontal slots are made at the top of the ceiling, at a distance of at least 15 cm below the ceiling.

Now, in my case, conduits are installed in the ceiling with small distances between them, but they all lead to the same power strip.

Should I really first go 15 cm down from each conduit and then channel all of them into a common horizontal slot to the left and then vertically down?

Or can I, in such a case, directly make a horizontal slot to the left at the height where the conduits come out, i.e., about 3-4 cm below, and then go down?

What is the best way to do this in practice?

Thanks and best regards!

Where the cable runs is basically irrelevant. You should just document it. I mean, with the greater distance you can mill better and the bending radius is also more elegant.

Why are they all going to the socket? Aren't they a bit short? Lay them so that it's easier for you. It doesn't really matter, as long as you know something is running there. It would have been nicer if you had drilled at an angle about 5-10 cm below the ceiling before pouring the ceiling. Then you wouldn't have work right at the edge. Now you probably have to resort to hammer and chisel.

Hello quattro 123

4 empty conduits for 4 sockets. What will be laid there?
Possibly 1 or 2 empty conduits right up to the socket. Can be supplied with new cables at some point.
Otherwise, you can lay the cables as you like.
If all empty conduits are cut at the ceiling, I would pull two 15cm below the ceiling to the left (you can't reach directly under the ceiling with the wall chase cutter) and I would run two cables vertically down to socket height and then horizontally up to it.

So the empty conduits have been installed in the raw ceiling. I will cut them off and then lay the cables under plaster...

There are two sockets, one LAN and one SAT.

I also spoke with the electrician again. He said it's fine as it is.

Thanks for your help

Hello quattro123

and exactly for the LAN and SAT socket I would lay the empty conduits up to the socket. It’s just a bit more work. But if it ever becomes necessary, you can replace the cables. Especially with the Cat cables, there is constantly something new.
Better to have and not need than to need and not have.
