How to distribute wiring in a three-story house by floors?
Good afternoon, there is a cottage three floors.
1) There is a problem of installing one large shield on the machines on all floors - there is no place for it. I want to install three small shields on each floor, and pull wires to each floor from these shields. Question: 1) is this the right decision 2) how to bring the cable to these shields after the counter 3) Are there any additional points. thank
Good afternoon! For your questions:
- Correct only if you connect the cable of each floor to a circuit breaker (introductory).
- In the sense? Just like any other.
- No, there are no special restrictions. But personally, I would make a small electrical panel at the input, where I put the machine on the cable of each floor automatically. Then it will not be necessary to think how to connect the three phase conductors to the input circuit breaker (each core will have its own, and zero on the bus), and the circuit will be more reliable, because in the event of an overload or short circuit on one of the floors or cables, the others are more likely will continue to work.

Good afternoon!
And who (or what, what rules ...) prevents you from leading from the opening automatic machine of the house to the main line to the floor shields (in fact, this is a loop). To ensure the selectivity of the introductory machine of the house and the introductory floor machines.
For example, an introductory machine at home C63, a floor opening machine C32 (or even B32).
Examine the issue in the context of multi-apartment 3-storey buildings, provided: 1st floor - 1 apartment.
