Laying a separate line for powering electrical appliances

The situation is this, my wiring in the wall is weak, and there are a lot of electrical appliances. There are 16 amp automatic plugs on the counter and they are constantly knocking out if you connect 2 computers, a refrigerator, an iron and a washing machine at 40’s at once, turn on the bulb and cut off the plug due to the wires being heated. And I have 2 more Conders of 3800 W each, TVs 2, a microwave, a pressure cooker, well, there are some little things there, including also 150 W incandescent bulbs. In short, I, a kettle in an electrician, so as not to hammer the wall to change the wiring, I started to draw a parallel, power network for individual elements of electrical appliances. By the way, I don’t have an earth wire in the house, as it is, PEN is called in my opinion, in general two wires are only phase and zero. From the bottom terminals, which under the plugs (not the top ones, which after the plugs) led two copper cables 4 mm in diameter, single-core lived and through IEK C50 brought to the power distribution bus with the same cable. From these buses (phase and zero, two copper plates with terminals) I brought out three lines through IEK and C20, two to air conditioners and one to the kitchen and bathroom, I connected 25A 30 mA to the bathroom and RCD. Given the cross-section of the wire, in general, several welding machines can be connected to them. In general, in my eyes this looks certainly funny, but I still did not dare to put plugs on the bottom terminals of the plugs, because vague doubts torment me. I calculated the power of all electrical appliances that can be accidentally turned on simultaneously on all branches, divided by 220 and I got 47.3 A. This means that 47 A will hang on the lower terminals of the plugs, and on the upper terminals that go from the rooms with wiring in the wall, there will be approximately 12A. The question is, will plugs 16A be triggered when 12A goes to them, and after them 47A? Thank.
