    About 21-26 And it all depends on how you arrange it

    In order not to create a new topic, I will connect to this one. Namely, can I connect a 1-phase resistive load of 4000W to 3x2.5mm2, it is about 17.4A, the cable will be laid on plaster or, if necessary, in plaster, and then covered with cardboard gypsum. The tables I reviewed allow such a burden, but I would like to ask practitioners.

    Withstands (ideal load resistance does not actually occur). For this type of cable, the optimal constant load is 22 A, with higher current the cable starts to heat up. The highest load that I was able to measure on this cable is 32A. it was installed flush-mounted and the protruding end in the switchgear was very hot, in such conditions it withstood over a year

    Thank you for your response.

    So you don't have to put it under the plaster because it gives off heat better?

    Another question arose: To what long-term, harmless temperature can the popular YDYp cables work?

    ps. It will be an accumulative furnace, so 99% of the power will be consumed by the heater.

    This is a glass rub.
    If the cable is yet to be laid, why not 3x4mm??

Topic summary

The discussion revolves around the maximum power capacity of a 3x2.5 mm² YDYp cable used in a home corridor. Users provide varying opinions on the safe load limits, with suggestions ranging from 21-26A as a safe constant load, while some report that the cable can withstand up to 32A under certain conditions. Concerns about heat dissipation when the cable is laid under plaster versus exposed are raised, along with inquiries about the long-term temperature tolerance of YDYp cables. The conversation also touches on the possibility of using a larger 3x4 mm² cable for better performance.
