Replacing a Room Switch with a Socket for Additional Power Source - Brown, Blue & Yellow Cables

Hello,

Is it possible?

In the room where there is no socket, there is only a switch. Can outside the basement.

In the switch there are brown (phase) cables connected to the blue one through the switch (I understand that it closes the circuit further to the bulb) and yellow-some unconnected (protection). Is it possible to obtain an additional socket (or exchange for a socket)? The only thing that comes to my mind is to give up the lighting - we connect it permanently at the bulb, and connect the cables from the wall (all 3) to the socket ...

Theoretically it is, but in practice it is not allowed to do so.

Hello,

Is "in practice you mustn't do that" is it a result of some danger/threat or is it about the purity of the network design methods ? Are there any significant contraindications? I care about this outlet, but if it's supposed to be dangerous, I'll spare it...

Regards and thank you,
Wojtek

What type of network do you have?

is a new installation (annual),
3-wire,
meets all new standards for sure,

more precise information is unknown to me now,

So probably TN-S, unfortunately, but if you make this socket, it will not have proper grounding, so in some circumstances it can be dangerous. Can't you pull a new wire from the box?

This will be completely against the rules and you will do so at your own risk.
You can connect this yellow-green wire in a box with a working zero (probably blue) and connect a plug socket to the point obtained in this way. The method will not work if the installation is protected by a differential circuit, unless you connect the socket pin to some ground.
Once again, I would like to point out that this is completely against the rules for the construction of electrical installations.

I greet everyone

So, I'll make this change...

I'll try with a can (far away and I wanted to avoid that...)

Thank you for your help,

Hello, regarding the room, I understand that it is located in the basement, so any installation of electrical sockets should be agreed with the administration. as for the wires you mentioned here, it is actually as you write, except that the yellow-green does not have to be protective in this case, it can act as a spare, apparently the installer did not have a 3-wire cable without a green-yellow wire

after reporting to the building owner, you will receive permission to install the power supply circuit for the socket, it is often the case that the administration defends itself against such modifications by using various security measures

I think it's a bad idea, if you want to do that, you have to change the connections in the junction box

To connect the socket, you must have phase and neutral, or ground, depending on what type of network you have. In your case, you probably only have a phase - a brown wire that goes through the switch to the frame with a blue wire. You need to find zero and pull up to where the socket is installed. Maybe from a light box. As for the yellow-green wire, you also need to find its other end, it should be grounding, but it may as well be not connected anywhere.

Hello.
You can safely install the socket in two ways, but unfortunately you need at least a minimum of knowledge in the field of electrical installation.

Hello,

And is such an invention OK???

I admit I was surprised...

Firstly
The phase, working neutral and protective neutral (L1, N and PE) are connected to the switch box. Colors for L1- dark, for N-blue, for PE-yellow-green
If so, the installation is capable of installing a fully secure network socket. This can be checked with a measuring instrument.
Voltage between L1 and N =230V between L1 and PE=230V between N and PE =0V
Connect the socket normally. The socket must be of the hermetic type, with a PE point. normally connect the lighting switch to your lighting point, observing the rules of grounding current receivers. This is in line with PNE rules and regulations. You can build your system in the set p/t switch + socket. They can also be installed separately.
IMPORTANT!!!!!
YOU MUST NOT CHANGE THE SIZE OF THE CIRCUIT PROTECTION IN THIS SYSTEM!!!
IF THERE IS PROTECTION 6A IN THE CIRCUIT, THEN IT MUST BE THAT!!!!!!!!!!

what new type of switch? I suggest you educate yourself, not write nonsense...

people, and since when do you mix electrical circuits?? I do not know if maybe I went to school too long and something has changed in this matter, but if there is a lighting circuit, it is supposed to be lighting, as it is powering the socket, at most it can be converted into a lighting one by connecting a lamp to it through a plug. connecting the socket to the lighting circuit may cause some large load to be connected, the fuse will work, the maintenance technician will come and look for damage in the lighting fixtures, you want to be in his place because I don't

I repeat, such modifications must be agreed with the building administration, rarely the administration agrees to the installation of sockets in the basement, unless a sub-meter is set up, otherwise it is simply electricity theft

The inconsistency of the network contractor is often encountered if the luminaires are insulating - PE is not connected. Often, the yellow-green wire is used as the return from the circuit breaker.
In a circuit where the installer has taken the easy way out, fitting sockets is basically delayed suicide.
The second thing is the impact of the loads connected to the sockets on the work of lighting.
The third - the lighting of the basement comes from the administrative circuit, calculated by the meter. Its readings are divided into the number of tenants and each connection to such a circuit is robbing the neighbors.
Not everyone in the building wants to pay PLN 10 more, because someone else wants to play with a drill in the basement for free.
Fourth, the failure of the device connected to the socket entails the failure of the entire lighting. Theoretically, you can make a separation, but if the lighting has B6A, it's a problem.
The fifth thing is the cross-section of the wires. Lighting bulbs are not made with 2.5 or 4...
If you want to do it "in a human way", lead a separate circuit from the main board, properly secured and with a separate meter - it does not have to be legalized - it can be used by the Administration to write off your wages from general wages.
