Connection Power in Apartment: 3 kW, 1 Phase, 20A - Can Electric Oven (3.1 kW) & TV Operate Safely?

Good morning !

Due to the fact that I know little about electricity, I decided to write here.
I have already seen a similar topic, but it has been closed.

I bought a flat with my wife whose connection power is 3 kW; 1 phase; 20 A counter-counting security. Flat from the early 90s
Due to the fact that the old stove (with gas oven) is falling apart, we decided to look for a new gas kitchen, with an electric oven. And that's why the question about which power to connect the oven to choose, so that when using an electric oven could work, for example, TV and not break the plugs and is this the only criterion? Stoves that interest me have a connection power of 3.1 kW and I wonder if the installation will withstand it. Because it's a bit "on the spot". In the store they will probably say yes, provided that I do not use an electric kettle at the same time. I saw that there are some ovens on offer stores have a power of 2 kW, but this probably involves some restrictions on the oven.

Start by increasing the power to five kilowatts, because what you have now will come into existence sooner or later.

Hmm, but you probably need to change the 5 kW electrical system in your apartment?

Nothing needs to be changed, but it may turn out that a new circuit for the planned oven may be necessary.
Here you should invite a cougar electrician who will make a decision on the spot.

It is worth noting that 3kW connection power and 20A protection only correlate at cos? = 0.65.
With a resistive load with cos? = 1, the author has available 4.6 kW.

Indeed, with 20A pre-meter protection, the connected load is 4kW. It is worth checking again in the contract or on the invoice.
