NNN asks:
Good afternoon. Please tell me how to be in such a situation. From the developer around the apartment, a copper 2.5 mm two-core electrical wire (except for one socket with grounding). In the kitchen, from the socket already installed by the developer (without grounding), the master led me 2 two-core wires with a cross section of 1.5 mm each without grounding (1 for the hood, 2 * for the socket for the lighter). From the 2 * socket, the same wire is further laid and the washing machine is connected. Now the question is about installing an electric oven, and it is planned to connect it to a 2 * socket.The question is this:
1) is it safe to use this socket to connect an electric oven?
2) is it possible to additionally connect the hob to it (only for electric ignition)?
3) How much power can the oven be installed?

Hello!
- Both the oven and the washing machine (as I understand them, you will connect them to one outlet) imply connection to grounded sockets. That is, without grounding, their use, by definition, is not safe.
- Gas hob? If yes, then electric ignition is a negligible load, so you can).
- The maximum current for most outlets is 16A, which means that the maximum power of the connected device should be: 220 * 16 = 3520 W or 3.5 kW. There are special sockets for connecting electric stoves and ovens. You may have seen them - with flat, thick pins. But questions with your cables (below).
Your wiring itself is unreliable and not entirely secure. Why is there only one grounded socket? Every single outlet, judging by what you wrote, is wired with a wire or cable with a cross-section of 2.5 sq. mm. Then why did the master lay the wires from the existing outlet not with the same cable, but 1.5 sq. mm?
It is better (this will be correct) to lay a grounding conductor to the sockets in the kitchen and power them from a separate machine and protect the RCD, after all, there are already two dangerous factors - humidity and high temperatures.
As for why the 1.5 mm wire - the master "quietly" just bought the wire that he found in the nearest store and without asking me, he bought and installed it. That is, I have already confronted the fact simply because the same wire was brought along the ceiling to the zones for the installation of built-in lamps. The work on laying the apron with tiles followed, so there was no time left for disputes and alterations.
How can I now route a grounding conductor to this outlet? Pull it across the kitchen to a grounded outlet? How to power it from a separate machine, if the finishing is all done, and the stretch ceiling??? directly the one who laid the electrical wire said that the oven can be connected without fear, another master (later) said that the wire must be at least 2.5 mm. Therefore, I am at a loss, how not to burn the whole house. A gas oven is also not an option, since there is only one branch from the riser, you cannot put tees
