How is the installation in the switchboard according to scheme e4 carried out?

Question

Electronics

How is the installation done here?
x1, x2 - tires. QF switches.
1. tires, switches are installed in the KMP.
2. L, N, PE are incoming wires? then N and PE are put in the tires, but where does the phase L go? In general, please help. What technology is here?

Answer 1

The PE busbar is without options a busbar with wire bolts.
The N bus can be the same as the PE bus, with the switch inputs connected to the bus by wires.
But there is a better option - to take a two-pole comb bus, it will be an N bus and an L bus at once, the shield with the comb looks neater. The excess length of the comb is cut off.
If the installation is without a comb, then you can use a stranded wire and NShVI lugs for installation.
It is bad that in the diagram the introductory switch is single-pole, it is better to replace it with a two-pole one. If QF4 goes to lighting (otherwise why is it not a differential automatic, like the other two?), then 16A is bold, it is better to put 10A.

Answer 2

Formulate a task. What is needed?
What is E4? KMP?
Are you collecting a shield?
The shield includes one three-wire cable and includes three.
One common introductory and each line is protected by a difavtomat.
For zero and phase tires are not needed.
But for the earth - it is necessary.
Oh, and don't forget the colors. Blue - zero, Yellow-green - earth. Color - phase.
