There are 30 rooms on the first floor of the hotel, each with 8000 watts. How big is the main line and open space?

Each room needs 1.5 square main line and 40 years of open space. It is recommended to choose a larger open space, because people who live in it will also have other electrical appliances to use. 8000 divided by 220 equals 36, and the conservative estimate is 40 a. You can also choose a bigger one. The corresponding main line is 1.5 square meters.
