ᐅ Which flush-mounted boxes are used for network cables and for cables with five entries?

Hello,

I am currently building a house and preparing the electrical installation.

My questions:

1. When installing network outlets, are standard deep flush-mount boxes sufficient? And is it acceptable to route the network cable through the middle cable entry points rather than the lowest ones (see file)?

2. Throughout my house, M25 conduit is used for wiring. If I have five cable entry points in a flush-mount box, can I still use deep flush-mount boxes, or should I rather use device connection boxes such as the Kaiser model with item number 1069-02?

Thank you again

I would reconsider this approach. Ideally, you shouldn’t have 5 cables terminating in a single box anywhere...

Always use the rear-most entry. Especially if you plan to install dual LAN. The inserts themselves also have a significant depth. Plus, network cables are quite stiff.

The junction box you linked to is definitely top of the line.
It allows you to neatly store some extra cable inside the box, which makes connecting much easier and also leaves you with some spare cable for the future.
I recently did it this way myself.
Great.

Well, I have already installed the conduits in the concrete ceiling.
There are recessed lights in the ceiling.
My power supply goes to my switch, and from there it branches out in a star pattern, meaning one lamp, one power feed, and then two to switching devices (intermediate switching setup).

Always at the very back. Especially if you want to install dual LAN connections. The modules themselves also always have a considerable depth and length. And network cables are stiff

Well, I have already installed the conduits in the concrete ceiling. The ceiling contains spotlights. My power supply goes to my switch, and from there it branches out in a star configuration, meaning one lamp, one power supply line, and then two switching elements (intermediate switch wiring).

But there are only 4, right? Also, you can easily combine a switch with a socket outlet underneath, and then you already have 2 flush-mounted boxes in the same space.
