Is it enough for me to use 30KW three-phase four-wire 10 square copper core for three-phase electrical equipment in the hotel? How big is the meter and how to shunt it?

35kw phase current = 35/0.38/1.73 = 53.24a; The single-phase current is 25kW = 25/0.22 =113.6a..

The current density of copper core wire is 3 6A/mm2, and the cross section of the wire should be:

1 13/5=22.6 square meters (the standard wire diameter purchased from the market is 25)

10 square is not enough.
