Hello kindly.
A 4x4mm2 cable (diameter of the vein with the cover) is led to the summer house.
Three veins are one and the same phase, and the fourth lived as neutral.
The contract with Tauron says that the contracted / connection capacity is 5KW, and the place of connection "Cable connector". Counter 25A protection.
And now, who is responsible for this cable from the box at home to the box with the meter? Does the first electrician with rights have access to the box with counter-meter protection and has the right to change the configuration of the connected wires, or do you need to take someone from the ZE?
Why such wiring connections? The current in the circuit flows the same, regardless of whether it is a phase or zero, and therefore symmetry should be maintained.
I also found in forums that people sometimes have more than 11KW power allocated on a 25A fuse and I ask how it should work if 25A * 230V = 5750W?
I am also wondering if the current cable will be sufficient when I use two wires as the phase and the other two as neutral, with the load in the house: fridge, 7.2KW induction hob, 4.5Kw water heater, electric kettle, and a few smaller devices. Generally in 13KW I should shut down wanting all devices to be turned on full.
And so at the end I wonder the thickness of the neutral wire in installations with strength where we have 3 phases. Shouldn't such a vein be thicker than the others?
Best regards.
