How to set up electrical systems. Part 1.

If you have a 2-3 - storey house does not need to drag kilometers of electric cables from a single distribution.
Preliminary section from which to go out one by one in big cross-section cable on each floor. And on each floor has its own distribution.
1 central distribution:
It surge - lightning protection, further leakage maker (fuse 300mA),switch 25A and 3 switches which allow you to unlock every floor.

Floor distribution looks like this:
leakage switch 30mA = 0.03 wet areas. If you want you can lining to all zones separately. And on Automatic electricity switch on the beam 10A and Automatic electricity switch - sockets 16A. Cable cross-section of 3x2.5mm/2 sockets, - on light 3x1.5 mm/2

Followed selectivity. If the sockets Automatic electricity switch 16 A, then one must be the distribution 20A and input fuse 25A.
