What cable to conduct electricity from the metering panel to the house?
Hello. I have a shield on a post near the house (pictured). The declared power of 15 kW. The introductory machine and the subsequent, after the counter, VA47-29 C25 are connected by jumpers with a cross section of 4 mm. What cable (mark, cross-section of conductors) to lead to the house (by air)? And then into the house to the switchboard. We carry 220V.
I suppose the cable to be lifted along the column (3-4 meters), then to the house 14m, and inside the house (in a metal box) about 5m more.
Currently installed in the shield:
new DIN rail
tire N
PE bus (jumpered to N bus)
author switch 16A (connected by jumper from one of the phases with C25)
220V socket.
Thank you
Sincerely, Igor Babarykov.

Hello! Why are you driving a 220V three-phase input? Through the air, all lines are laid with a SIP wire, in chapter 2.4. PUE in paragraphs 2.4.13 and 2.4.14 says that self-supporting insulated wires should usually be used on overhead lines (this is SIP), and according to the requirements for mechanical strength, wires with a cross-section of conductors on the overhead lines to the inputs should be used no less than 16 mm².
p.s.
15 kW for you with three phases, as I see it (25A 3p automatic), for 1 phase there is 25A, i.e. 5 kW
