Wiring diagram in a two-story house with two shields

Hello! When designing the electrical wiring of a two-story house, I came to the conclusion that it is necessary to install two shields, one each on the floor! I decided to install the introductory shield on the street! I also decided to install a generator that would power only the second floor. He made a diagram. Does this scheme have a right to exist? And what errors are there? Thank you in advance for your help!
