Hello everyone. I have just become the owner of an apartment with an area of 60m2. The apartment is undergoing major renovation, currently I do not have electricity in it because the meter has been removed after the eviction of the previous owner. There will be 2 TVs, 2 computers, fridge,...

This chart should bring some light to the problem. I think 12kW is enough for you. Well, unless you intend to connect 3-phase motors ...

It would be appropriate to have 25A inserts on the pre-meter protection, it gives a power of about 15kW. The more economical version is 20A inserts and a power of 12kW. Take a look at the example table in this post:

Hmmm I was thinking about 7-8 kW

It can be 4kW in one phase or 12kW in 3 phases.

Gentlemen, if I let go of the topic of the induction hob, what power is enough for me, maybe then it is worth staying with a single-phase heater? In general, I got a little lost in all of this (a layman if you want electricity)!

Buddy, there is nothing to get lost. Each device has a specific rated power and usually gets such power. First, add it up (also the future ones not yet purchased) and see how much it will be. If you want the 'comfort' version, take that power and you don't have to worry about a possible back-out. However, in the 'economic' version, take into account that you will not be able to simultaneously use some power-hungry devices, which can also be troublesome (especially women like to turn on everything at once )

Buddy, there is nothing like a 3-phase power supply! You will divide it into rooms and you will not have overloads. In addition, if one phase is missing, you will have electricity in the other rooms powered by 2 living phases, because before the Power Engineers move, sometimes you have to wait half a day. Once it's worth paying for comfort for the rest of your life, so these 12 kW are a good idea!

So I can raise the power to 7.3 kW from the current 5.3 kW, then I will have 32A and the board will work on one phase

Hello. Provided that ZE gives you such a power allocation.

I have to apply for conditions.

Hello everyone.
I have just become the owner of an apartment with an area of 60m2. The apartment is undergoing major renovation, currently I do not have electricity in it because the meter has been removed after the eviction of the previous owner. There will be 2 TVs, 2 computers, fridge, washing machine, dishwasher, oven, electric kettle in the apartment. I am also planning to buy an induction hob. The standard power that is supplied to the apartments in this block is 5kW single-phase. Taking advantage of the renovation, I will replace the installation with a 3-phase one, but I do not know what power to write about, how many kW is enough for me, I ask because each 1kW costs about PLN 180. Please reply urgently.
Best regards and thank you in advance to everyone for your advice.

Buddy, the power you want, you will take it, but remember that it should be 3f and that the power cord has a lot of reserve, e.g. 10mm ^ or even 16mm ^.
You will not overpay much and you will certainly save yourself "spitting in the chin" in a few years.

Yes. Only first to the building administrator for (written) consent, and then to the ZE. If you didn't know ;-)

And in general, if you are a layman in the field of electrics, you will not forget to hire a professional. So it's best you do it right now.
