Connecting Switchboard and Meter: Proper Order for Differential and 16A Fuse Distribution

Question

Hello
I live in a block of flats from a large plate. I have replaced the entire installation with copper and I only have to connect the switchboard along with the meter. My problem is that I would like to give a differential to the bathroom only that I have heard that there must be a proper order as to the point of distribution of PEN to PE and N and a 16A fuse. I have drawn such an overview schematic and I would ask for possible correction of my concepts

There is nothing to correct, the concept ok Only such ot question why do not you give the rest on the differential?

fchancuz · Answer

because the rest are living rooms that are equipped with sockets with pins (as a precaution in case of war and Indian attack ) but still to these sockets are connected devices that have flat plugs through the pin such as TV, video, dvd, night lights, cell phone chargers so here the differential is probably unnecessary ....another part is lighting, which probably also does not require a differential and finally the kitchen, which for financial reasons will get a separate differential in the near future ... I do not want to put everything under one differential because it is probably a little impractical because I will be deprived in this way, for example, the lighting at night when the differential will fire ... I'm saying it right?

Hello Kolego fchancuz , then still let the colleague describe how this installation to the outlets (with protective pins) in the rooms is made.

fchancuz · Answer

cables to the rooms (3x1.5) have 16A protection. Zeroing is done at this point what is on the drawing and from it the PE and N wires are coming off...is there anything else I should specify (I don't know exactly what colleague Ele_pp asked...)?

jarewa · Answer

The differential protects a person. In the absence of a protective conductor also protects a person. In the case of puncture and touch. But there must be a condition that meets the tripping of the RCD. So even with the so-called cell charger may be needed.

hmm then I could make it so that I hook everything up to this differential except for the lighting (so that in the dark at night I don't have to look with my hand where the electricity is turned on...) will this be adequate? will this be adequate?

Miwhoo · Answer

First, up to 3x1.5 is given B10, not B16. Secondly, the RCD should protect all plug sockets.

Lighting does not need to be clipped to the RCD.
In order, it should be like this:
- separation of PEN into PE and N [PEN enters the PE bus, and from it only to the N bus]
- RCD
- circuit protection

Good practice is to give a separate RCD for the bathroom, a separate one for the rest of the outlets.

How about the installed power and pre-protection?

fchancuz · Answer

I do not know what power is installed but ZPL is 25 or 20A...(I do not want to go to the cage and check

)
but this B16 serves a total of 3 rooms in which there is a total of probably 8 outlets (each has a separate 3x1.5) so I guess it is correct?

that is, I can plug all 3 rooms, bathroom, kitchen under one differential then each separate fuse and give lighting without RDC?

Anonymous · Answer

Wire 3x1.5mm^2 can be used for power supply in socket circuits in special cases and with B10A per wire, which gives max. 2.3KW load. RCD is designed to protect against electric shock in a specific electrical circuit, not circuits.The use of one differential for the entire apartment is pointless.One for the kitchen and bathroom, and you can give one RCD for the other rooms.

fchancuz · Answer

that is, I have to replace the B16 for the rooms with B10... unfortunately, I do not have enough space in the switchboard to put 3xRCD so for now I will put one for the bathroom and then when I improve the budget I will add the second one for the kitchen.

It is not. It serves its purpose.

Any insulation failure, if only in an electric kettle, will turn off the lights in your entire apartment. And you will be killed not by the electric current, but by your own table against which you will bang your head falling in the dark.Greetings.

What will kill me without power is not the topic of this thread. So far, ZE has deprived me of power several orders of magnitude more often than a differential turned on for everything. Let me assure you that I am not writing from the hereafter.

This topic has been rolled out many times. Search and read on this forum. In addition, PN-EN 60364 Greetings.
