Converting 4-Pin Power Jack to Standard 230V Outlet with Multiple Sockets

Dear Colleagues!!!
I have a problem!!! i'm a layman!!!!
I have a board with a 4-pin power jack!!!
I need to switch from this socket to regular 230V.
Please tell me how to do it best! i.e. I would like to have a power plug and on the other side a strip with several sockets!!! maybe some kind of schematic??????, is there any security needed for this??????
I hope for help!!!!!!!!!
Thanks in advance!!!!!!!!!!! and best regards.

Ask a professional electrician.
There are no jokes with electricity!

relax!!! I know a little!!!! I don't have theory, only practice and willingness!!!
and without self-confidence!!! constructive comments please!!
I greet

You have 4 pins, i.e. there is no grounding, so the residual current fuse falls out.

I think you wanted to say you don't have zero, because the ground is on this contact!!!

So if it's an old installation, it most likely doesn't have a residual current device.
So you connect one of the pins of the socket to the protective conductor (grounding) and the grounding (pin) and from one of the phases the other pin of the socket.
You could still provide protection against the socket, e.g. S301 C16.
You can connect a different socket to each phase, then you will not load one phase

OKAY!!!!!
Thanks for the hint!!!
I am interested in 3 sockets.
From what I understand, I can, even should do each on a separate phase. I thought so, but thanks for the expert tip!!! BEST REGARDS

I love when people who don't know the basics start a discussion.
Zero, ground ... or maybe PEN, PE, N.
A friend probably has a PEN connected, so he can make it N. If it was PE, it's not allowed.
The layout of the TN, TT networks is also important. Then we know if we have PEN or N.

Earth is a protective conductor, it can be an additional one, now it is a requirement and in every new 3-phase installation there will now be 5 conductors. I think you got something wrong, in the sockets in the old installation there is zero and phase, not ground and phase. so it's definitely zero and 3 phase.

How do you know it's an old install?
Four-finger sockets are used to this day, and the following are connected: 3-phase and PE (Protective) wire I've already seen such installations where the customer called because the differential switch crashed and the "electrician" connected the neutral wire to the socket housing!!!

This is due to the rules that used to be in force.

Then why are these sockets still on sale and installed today?

So far it is known:
- Supply voltage: 3x400V
- Network layout: unknown
- Wiring: unknown
Hence:
- Only allowed arrangement: transformer 400/230 V,
- Protection against electric shock: protective pins connected directly.
- Overload protection:
Transformer protected by fuses on the primary and secondary sides,
the power of the transformer is much greater than that of the connected device.
A method suitable for low-power devices, e.g. soldering iron, oscilloscope,
computer, small power tools, not suitable for e.g. welding machine.
I do not recommend a toroidal transformer, even though it is cheaper.
Maybe something like http://www.indel.pl/p_tmd.html but in a housing like
http://www.indel.pl/p_tsop.html they will make it for you.
But since there are no such versions in the wide offer of a large company, it is rather
over there no one wants to explain themselves to the widow and the prosecutor later ...
Note: you connect at your own risk.
Better and healthier: invite an electrician who knows what and how you will do "to make it cheaper"
I hope my Real Electrician colleagues won't "eat" me...

PS: You should be ashamed of yourself for those bundles of exclamation marks,
but you haven't been here for long, maybe you haven't read the rules yet...

Witkacy, you know the difference between the protective and neutral conductor, because it seems to me that you have no idea. If you connect the phase and the protective wire instead of the neutral (zero), you will drop the differential, that's what this protection is all about. I am an electronics engineer by education, but my father is an electrician and I have worked with him many times and know about such things.
Geguś is right, now the regulations say that the installation should have an additional protective conductor (yellow-green) it used to not be, that's why the old electrical installation is distinguished from the new one

I know very well, I'm just trying to explain to you that to this day people put on four-finger nests. People install such sockets in new homes with new installations equipped with a residual current device.
And they install because most people have different devices with a four-finger plug.

And it's probably you who don't fully know, because when installing such a socket, we just connect the PE-protective wire to the housing of this socket, not any neutral!

Hello .
I'm guessing you want to make an installation extension cord.
I am interested in the length of this extension cord.

What are you writing??? When you connect 3 phases and the PE wire, the differential will automatically fly out. With a 4-pin connection in new installations, it is only possible to either connect 3 phases and N or not protect this socket with a differential and connect 3 phases before the differential and then you can use the PE wire (of course, if there is no other differential before).

of course, I'm talking about using three phases for 3x230V power supply

And here there are two different possibilities, because I'm talking about powering, for example, a 3-phase motor
And try to connect 3 phases and N and connect the motor and put it on a grounded metal table. What will happen to the rosary? Will throw

Well, yes, because you are talking about the use of 3 phases in the phase-to-phase system, then you only need to connect the PE wire. but with 3x230V power supply, you need to connect the N wire. It is best to bypass the differential in this case and connect the PEN wire and you can use 3x230V or 1x400V, because the differential does not work anyway.

To Witkacy8.

try it. If it flies out, connect the metal table with an equalizing cable.

To the author of the post -you wrote that you want to do it professionally, as best as possible. You can replace the socket with a PCE switchgear according to your needs-http://www.pce.pl/index.php?option=com_content&task=view&id=187&Itemid=256 First, however, check if this socket is not protected by RCD / I also met such a socket for 3x400V / and what kind of protection it has. You have access to the board, so there should be no problem ...

If it has a 4-pin socket, then the 4th one is the PEN cable, after leading it to a single-phase socket, plug it into zero and bridge it on the pin

But it's better to tell us what installations you have at home and what security measures we can infer
