    Do you understand the meaning of the phrase "will slide out?" ?
    It means mechanical movement

    Have you heard about the phenomenon of thermal expansion of metals? It is the mechanical movement caused by thermal expansion that causes the wires to become loose and, as a result, to increase resistance. If you insert a wire into the wrong side of the screw when screwing it in, the rotation of the screw while tightening can cause the wire to be held only by the edge of the screw head. And it doesn`t take much (just mechanical movement) for the cable to fall out from under the screw.
    Col. CYRUS2, I`m embarrassed that I have to explain such things to you. Well, it only says something about you.
    I would never advise someone to connect a cable to the receiver that could carry half of the power required by the receiver. And what`s more, we don`t know what conditions the cable will work in. Additionally, explaining that it is not necessary to use the full power of this receiver. And that`s exactly what you did. And that`s it on this topic

Topic summary

The discussion revolves around the installation of a 230V induction hob in an apartment with a single-phase electrical system. The user has a 3x2.5mm² cable and a B16 fuse, with a total connection power of 4 kW. Concerns were raised about the adequacy of the cable size and fuse rating, especially when multiple appliances are in use. Responses suggest that while the 3x2.5mm² cable can handle the load, it may be insufficient for high-power induction hobs, which typically require a 4mm² cable for optimal performance. Recommendations include applying for an increase in connection power to 5 kW or 25A protection to avoid frequent fuse tripping. The importance of monitoring simultaneous appliance usage was emphasized, as well as considering energy-efficient models that reduce power consumption. The feasibility of upgrading to a three-phase supply was also discussed as a potential solution.
