How to increase the power of the network from 8 to 20 kW?
The question is, is there a copper cable 4mm² in cross-section, accordingly it can withstand 8kW, the task is to make 20kW of power, and the voltage should not change as it went in and the output should be 220, which device or equipment is needed for this and is it possible?) it’s already confused in all these receivers, relay resistors, etc.) tell me pliz.
It will withstand 8 kW under the condition of open installation and protection by an automatic machine from the side of the power supply at 40A. And what you wrote is nonsense or you have been misled. Energy does not arise from nothing and cannot disappear into nowhere, do not believe it - open the physics textbook for grade 8. The current can be increased by lowering the voltage using a transformer.
To connect 20 kW, you must have an automaton with a rated current of up to 100A, a cable of the appropriate section, etc. Yes, and 20 kW is not a fact that the network company will give (or which company deals with these issues in your case).
p.s. The only option to get more power so as not to depend on the cross section of the input cable and the input machine is to put the generator or inverter (uninterruptible) of the required power! But it will be expensive.
