    Hello, I would like to know how many watts can be connected to one phase, I live in a dormitory and I would not like to burn anything but I want to connect 2 devices with a total power of 3.6KW or something can go wrong?
    I will add that I am completely green in this matter.

    If you go too far, security should work.

    HPS? :) 3.6kW is about 16A for a resistive load at 230V, so it is rather absent. It all depends on the overcurrent protection and installation.

    3.6 kW gives a power consumption of almost 16A.

    If so, the fuses may fly. It's best to ask the building administrator.

    From what I understood, 3.6kW gives 16A and 16A is the maximum current consumption on one phase anyway? So if I connected less, let's assume 3kW, it would not be a problem?
    How can I check without asking the building administrator about it?

    And it is not known if 16A is the maximum current consumption. Depends on the security features in the dormitory.

    Depends on your installation. I usually meet 16A overcurrent protections for sockets in the room, but I don't know how it is in dormitories.

    And I can check somehow without connecting these devices to the network and without asking the building administrator what the network security is?

    Look at the fuse box. However, I would advise you to give up on it, because it can only result in some misfortune.

    Better ask the building administrator because you can have 10 A security for one line. P (power) = U (voltage) * I (current). So count I = P / U comes out 3600W / 240V = 15A. If the administrator has installed "esy" 10A, the protection will work for sure. After all, 10A security was usually available for one room.

    We have 230V in Poland.

    Yes sorry ;) I forgot that we raised it from 220 to 230 and not from 230 to 240 ;) My mistake, I don't think anything anymore today.

    Rather more than 16A, not because standard sockets have max. 16A

    There is nothing to think about because the author is unfamiliar with the electrician, and if he starts to think about something, it can only be a misfortune. I consider the topic to be exhausted.

    It is not only about protection, we also do not know the cross-section of the wires (I used to meet installations with a cross-section of 3x1.5mm).

    Have you come across a method of selecting protections without the current carrying capacity of the wires?

    Yes ;) I saw an installation with 3x1.5mm cables and 16A protection in one apartment :) Installation made by a qualified electrician, and I do not see something that the 1.5mm cable can withstand such a load.

    It will endure. My point is that under * normal * conditions, the protection is selected taking into account the load capacity of the cables.

Topic summary

The discussion revolves around the safe connection of devices with a total power of 3.6 kW (approximately 16A) on a single phase in a dormitory setting. Participants emphasize the importance of understanding the electrical installation, including the overcurrent protection and wire gauge. It is noted that the maximum current capacity can vary, with some dormitories potentially having 10A fuses, which would not support a 3.6 kW load. Users suggest checking the fuse box for specifications and recommend consulting the building administrator for accurate information regarding the electrical system. Concerns about the risk of overloading circuits and the potential for electrical hazards are highlighted.
