    Hi.
    I will slowly start working on the electrical installation. I decided to run the internet cables right away.
    Unfortunately, this will be a job in installments. Room by room. I have an agreement with an electrician friend that I will do the work and he will come and install the electric cables.
    Along with laying the electrical installation, I would like to lay some pipes or something so that I can easily run internet cables later. There will be a few of them because I want to make at least 4-6 nests per room.
    I need some advice on what to use to run these cables. Any illustrative link or names are welcome. It will be easier for me to find myself.
    Thank you in advance for your help.

    You buy a corrugated pipe (conduit) fi28 and lay one separate pipe from the wardrobe to each room. If the cables are to be pulled in after painting or plastering, you will need to make some pass-through boxes to facilitate pulling them in (approximately every 10 m). Pipes must be laid with a minimum number of bends and with the largest possible bending radii (i.e. in the corners the connections must be cut deep and from a distance). It is very important that the pipe is not routed "in the air" anywhere. Then, when you pull in the wires, it will shrink and tighten the wires like a choke (you won`t pull anything in).
    As for the number of Ethernet cables - I would give two for each room for PC and similar (+ one possibly for AP). Minimum 4 for the living room. Additionally, you need to run coaxial cables to the TV and SAT antennas. If you go with SCR, which is becoming a standard, there will be one cable for each room. If the installation is based on classic fullband converters, there must be two cables to the room where you want to have a decoder with a recorder.
    UTP cables also need to be distributed to the alarm, boiler room, door phone, etc.
    It is also a good idea to run empty pipes from the patch cabinet to the attic, basement, boiler room and other sensitive places. If technology moves forward in 20 years, you just pull the necessary cable (e.g. optical fiber into the connection).
    Coaxial cables of at least class A+, and UTP network cables of category 6 or 6A.

    Do you mean that the pipe will compress like a spring?

    And here I added 4-6 cables, as I wrote earlier. A bit future-oriented. I assumed that in the future I would connect a computer, TV, maybe a console, or a printer - these are already 4 sockets occupied. You never know what else will come up.

    And I don`t get it, I`ll have to read it.

    With remote control!

    How does this remote control work?

    Normally, the conduit is plastered immediately with the cable inserted into it. I would advise you to do the same - unless the routes are planned, constructed, then the cables are connected, and finally the connection speed is checked by the electrician himself. And if it`s not OK, he`ll pay for the work to be done again.

    The electrician is to lay copper wires after familiarization. There are still aluminum ones on the floor where he will be doing this. He`s a specific, old-school guy, so I won`t even enter into a polemic about internet cables. Some time ago I ran cables upstairs, but upstairs. I hid it in the skirting boards. I already have some practice.

    I have already read something about problems with pulling cables in such corrugated pipes. Someone wrote something about smooth-wall pipes. Does something like that work?

    Is there any practice or standard regarding the height from the floor for placing such cables, or is it whatever you want?

    Once it tightens like a spring, reducing the cross-section of the pipe, it will then twist along its length into a spiral "like DNA"

    You will even need more than 28 fi. Maybe even 32 fi or two 28 fi pipes (two pipes are easier to lay and you don`t have to dig the walls too deep).

    The pilot is a steel wire inserted into the pipe. However, I recommend replacing such a remote control with a DY1.5 cable. The steel wire itself corrodes and tends to break off (if you don`t pull in the wires right after laying the pipes), and secondly, it cuts into the pipe when pulled in and you can`t pull the wires directly behind it. Sometimes even inserting a stay into the pipe behind such a steel wire is problematic.

    So, to insert the cable, you have to attach it to the remote control and pull it out of the pipe? There are no problems with putting the remote control back later?

    You pull the wires ALL IN TOGETHER. Previously, they were arranged nicely so that they did not cross each other but ran parallel to each other. You have to buy a few discs or measure the lengths and get addicted to it. One by one, you may not pull it in, and two... by pulling in a new cable when the others are already in the pipe, you may damage them irreversibly. When you pull in the cable, you rub it against those already pulled in and you will rub them on bends or other bulges. The problem is very important if you pull the cables in several times.
    If you want to still have the remote control for the future, all you need to do is connect the UTP and RG6 cables, attach a new DY to them and pull them together.
    And most importantly - whoever doesn`t lubricate doesn`t drive. Before pulling in the wires, they must be thoroughly lubricated with a preparation available at an electrical wholesaler. Then they will be easier to pull on and will not rub as much.
    To prevent the remote control from breaking (DY1.5 is a delicate cable), it is a good idea to first put a stay behind it, and then pull the actual cables after the stay.

    So this complicates the matter a bit due to the attic renovation being done in installments. I need to think better about this whole cable arrangement.

    The idea is that you pull them all together into one tube. Of course, you can enter other pipes at different times. You can also pull in the section and roll it up somewhere behind the cabinet in the room before the renovation.
    Of course, you probably know this, but UTP cables cannot be connected or extended (there is no need to cut the antenna cables unnecessarily, as the connectors may corrode over time). The UTP cable must be in one piece from the patch cabinet to the socket.

    Why so many and why don`t you put two (one as a spare) and use switches?

    For now, my plan is to install a rack cabinet in the staircase with a switch with X sockets in it (still to be determined). And from this closet run the cables throughout the floor to the sockets in the wall.

    Of course, I could run 2 cables from the bottom and do without the sockets on 2 small switches.

    Although my hamster is starting to spin around now and maybe you have another, simpler solution for it.

    What came to my mind now is 1 cable to the switch, and cables from the switch to the sockets. Only this switch should be hidden somehow.

    How many devices should be wired in each room at the same time? Probably a computer, possibly a TV and a console, think carefully about the amount of cabling.

    I`m already lost in this thread. Dear moderator, please do not delete information that is important to me.

    And on top of that, a switch powered by PoE

    I would run the cable to the attic from the first floor, from the switch that covers the sockets on this floor. The switch is not PoE. Rather, an additional switch powered by PoE will not work. Unless I`m wrong.

    There are "free-standing" PoE power supplies - like a box, on one side there is normal Ethernet and on the other side there is PoE.

Topic summary

The discussion revolves around the installation of electrical and internet cables in a home, focusing on the use of conduits for future-proofing. Users recommend using corrugated pipes (fi28 or fi32) for running multiple Ethernet cables (4-6 per room) and emphasize the importance of proper installation techniques to avoid complications when pulling cables later. Suggestions include using pass-through boxes, ensuring minimal bends in the conduits, and the necessity of lubricating cables for easier installation. The conversation also touches on the use of switches, the potential for Power over Ethernet (PoE) solutions, and the need for careful planning regarding the number of sockets and devices in each room.
