The hotel has 105 rooms. How big is the main current line of each room 15?

105 room, each room 15 current, total *** 1575 current. Because it is three-phase electricity, 525 currents will be distributed equally to each project (you won't get electricity from only one project and leave the other two projects empty).

1 square copper wire allows 6 currents to pass. 525/6=87.5

But heat dissipation should also be considered, and the problem line of overload should be thicker.
