Which cable to choose for entry into the house?
What cross-sectional cable is needed to enter the house? A refrigerator, light, a boiler and a washing machine will work. What cable to take to be with a margin and what is it called?

You can choose VVG cable for input or a little more expensive - VVGNG or VVGNG-LS (it is not combustible, it is better suited for a wooden house). The cross section of the input cable is quite enough 3 * 4 at your load. If it is planned to connect an electric stove, air conditioners, etc. with a margin and in the house, you can take a copper cable with a section of 3 * 6 mm.sq. at the input. That will definitely be enough.
Such a question: input cable to the house 2 * 6 cross-section. In principle, this section was enough, but recently they made electric heating with a boiler (boiler consumption is max. 6 kW, well, + pump). I think not enough, the old section will not be enough 2 * 6 the wire will warm up because In addition to heating, do we still use light, a kettle, a refrigerator, a washing machine? What do you think?
Is the cable copper?
Yes
6 mm sq. Copper withstands loads up to 10 kW. In your case, this is enough end-to-end, taking into account the fact that all consumers are unlikely to be simultaneously turned on. The most powerful consumers: boiler 6 kW + washing machine about 1.5 kW + kettle 2 kW. Total already 9.5 kW. Of course, it is better to run a cable with a cross section of 10 mm.sq., it will withstand a load of up to 15 kW, which is enough with your head.
I’m certainly not an electrician, but here you also need to take into account the length of the wire, I think that a 10/2 kV wire will survive but will warm up. I agree that I need to put 10 squares, but is it reliable that 15 kV will pull such a wire or is it better to buy 16 squares right away?
1 square cable can withstand 2 kilowatts, calculate it like that, and so that the cable doesn’t get warm, put the machine in and out, here’s your 50 year warranty
Calculate machines, 1 kilowatt - 5 up
