    Hello
    I can't find on the network how to calculate the conductor cross-section depending on the power of the devices.
    I have a problem that I wanted to throw a 4kW stove into the garage and I do not know if my cables will withstand it, I think I have 1.5 mm there.

    Hello. Mr. Grzeskk is right. I suggest choosing the YKY 5x4 cable, assuming that this garage is not far from the house (?). Let me mention that you will certainly connect other power sources as well as lighting. Greetings.

    I would like to note Mr. Marek Rozenblut, the YKY5x4 cable is an aluminum cable that is no longer produced, and besides, the Polish standard allows the use of aluminum cables from 10mm only. suggests OWY or YDY 5x4mm cable.

    Hello
    YKY is not a wire but a cable and not aluminum but copper
    the aluminum cable would be marked YAKY. Moreover, aluminum cables are still produced. The stove is probably not a portable receiver, so the OWY cable is probably not the best solution. I propose the YDY 5X4 cable, assuming that the furnace is 3f and the distance from the power box is large.

    Exactly, YDY will be the best solution - I do not know why my colleague suggested a cable 2 posts above ..

    hmm, and if it is an induction furnace and there is, for example, 4kHz at 50V?
    but I agree with my predecessors. especially when it comes to YAKY :)

    Hello. I'll correct the information. I mean the YDY 5x4 cable because it is cheaper than the YKY 5x4 cable. Sorry for the wrong word: wire / cable.
    I have not written anything about aluminum conductors, but I can see that my successors corrected a certain person. Thank you.

Topic summary

The discussion centers around determining the appropriate conductor cross-section for a 4kW stove installation in a garage. It is established that a 4kW load at 230V requires approximately 17.4 A, suggesting a minimum of 2.5mm² cable. Several participants recommend using the YDY 5x4 cable, which is copper, as a suitable option, especially if the stove is a three-phase unit and the distance from the power source is significant. There is clarification regarding the YKY cable, which is noted to be aluminum and no longer produced, while the YDY cable is preferred for its cost-effectiveness. The discussion also touches on the distinction between aluminum and copper cables, with emphasis on the correct specifications for safe installation.
