Connecting Two Different Sockets Without Grounding: Main Cable Bridging Inquiry

Hello

I don't want to start a new topic and I have a quick question if I can connect my 2 different sockets in this way, my main cable probably has no grounding and I don't even know where it is connected, so I immediately thought to make a bridge on this main cable and not to do it on the sockets bridge

Does the block have an administrator, a manager? The latter should know whether his facility is connected to the power grid in the TN or TT system.

Everyone is connected to Tauron, now I've found out that some apartments have grounding in my block, but I don't know which one they will sit on, I'm only interested in whether my connection is good according to the drawing, because I'm not going to change the installation for the moment

I only have 1 photo of connecting 2 sockets to this main wire, there you can see that zero is made right away, but I do not know now whether to feed it in the sockets again






The main wire is the one from above, and at the bottom you can see 2 more connected to it and 2 different sockets to them

And how did you turn off the voltage on this wire??

It's probably connected to one of the fuses, I have 4 of them and one of them turns off the power in the bathroom when turned off

What can I connect it like this??

Don't move anything. Contact the property administrator.

I note that in the bathrooms there was one socket from some circuit and the other dedicated to the washing machine on a separate fuse. This may be of great importance for your safety because I see that you describe the plus and minus in the socket.

Maybe it has DC power?

Let it have 24VDC then it will be safer

In general, what you write in the topic is correct. If there is no other option, "zeroing" is done for now, this time separating zero into PE and N as soon as possible. That's why it used to be done at the sockets, and now there is a separate protective conductor, so as to minimize its damage / loss of continuity due to current consumption. It is also currently separated much earlier from wires with a larger cross-section, which is more reliable in terms of damage.

This does not change the fact that you should know the layout of the network and the protection applied, because it may not be "zero". Judging also by this attached photo, I dare say that nothing is certain in this installation and some fern was rummaging in it and it is necessary to completely check and correct it by an electrician measuring. Probably then more things and errors will come out more important than the illusory security of this one socket.

Thanks for the advice, however, I will call an electrician and let him check what is going on in these cables, for the moment I quickly connected it without zeroing, i.e. I had 3 wires, so I twisted each wire in the socket in its place, then I did a test with the meter: plus to the socket and minus to the pin and on the meter it showed 230V does it mean that there is already a zero on the wire somewhere before ??

@omaxp
In the current situation, check that there is no phase connected on the protective pin.

I checked with the meter:
Only the left hole in the socket with a pin gives 230 V, is this normal??

This left hole should cause the voltage indicator (so-called neon lights) to light up. Other pins in the socket, especially "Bolec" do not glow during the test with a neon lamp. Be sure to check the neon lamp in another working socket beforehand.

Left with right is also supposed to be 230v.
