[Solved] A strip connected to a socket without grounding - what is the risk?

After a small renovation, I decided to connect a computer in one of the rooms, of course using the power strip. Unfortunately, it turned out that there is no earthed socket in the wall, which worried me a bit. But when it is a must, I connected it and it works.

However, if someone has ever looked at a box by a strip, he must have noticed the inscription "Use only in earthed installations!" or something like that So my question is, what is the risk of not complying with this rule? Will the surge protectors just not be effective, or is there something more serious about me?

Since you have two wires in the socket (phase and neutral), connect the neutral wire to the "pin" and you're done. You will have a socket with a pin and everything will be ok. Unfortunately, the older installations were made in a system where there were only phase and neutral wires (without the protection).

Since I am not an electrician, I have a few more questions that I would like to know the answers to:
1. Should I understand that I have to branch the neutral and release it additionally on the pin?
2. What will this solution really give me?
3. If I do not do this, what could be the consequences of not grounding the strip?

If the strip is connected with an ordinary plug, it can be plugged into the socket even if you turn it by 180 degrees. , there is a risk that after such insertion you will have 230V on the housing of the strip.
As you have noticed, each computer power plug has a third "leg".
It is connected to the housing of the power supply, and the latter, as it is made of metal, connects to the computer housing.
Interference filters are installed in the power supply, the neutral point of which is connected to the housing.
As there are capacitors, at this point, with the power supply on, it is approx. 100V.
It can "kick" quite well, and secondly, such a filter without a grounded mass point does not fulfill its task.
The computer "sows" interference.
I solved it in such a way that point I connected the zero strip to the heating system, which is grounded.

Hello

If you have a socket without a pin, then no matter how you reverse the plug, you will have the voltage on the housing (alternating current - that's its nature), you can easily check it with the popular "neon" by touching the unpainted elements of the housing (the neon lamp will glow), or a method for the brave ones, touch the unpainted part of the housing and, for example, the faucet of a radiator or even a concrete wall, preferably with the outer side of the hand. This phenomenon is caused by the power supply, which is a switching power supply.
My colleague jaga134 is right, you can make a bridge in the socket too, so I have it at home. It is important in the first place for the protection of electric shock, and secondly for the protection of the equipment, because this voltage can reach 120V and appears even on the mass of the motherboard and other computer components.

The use of a grounded socket is simply necessary !!!!!!!

This is not due to the "nature of alternating current", but to the design of the power supply, which has already been explained.

If he bridges the pin in the socket - there is no risk of reverse connection of the strip, it would be dangerous to bridge the extension cord / strip in the plug, since the strip requires a grounded socket, it is probably obvious that it has a plug with a place for a grounding pin and it cannot be inserted into the socket the other way round...

Oh me, you scared me. So take it easy again.
I have a blue and a black cable in the socket. As I mentioned, I am more likely to be IT specialists than electricians. Then I have to branch the neutral cable (which color? Xd) to the pin, as my colleague advised at the beginning, or should I do something else?

First, buy a socket with a pin and a "test tube", then use it to determine which wire is neutral (it should be blue, but it must be verified). Turn off the fuse on the circuit where you have the socket, disassemble it completely, put a new socket on the wall in its place and connect the phase wire to the left terminal and the neutral wire to the earth pin, then bridge the earth pin with the neutral terminal. Finally, replace the socket housing, turn on the fuse and use a test tube to check the correct connection.

I've seen a lot of computers plugged into sockets without a pin and they were digging, of course, attempts to reverse the plug by the owner of such a computer made me laugh. Such people claim that they will reverse the plug and it will be OK and here the surprise is not OK. There are many simplifications in my statements. Many devices, even without a power supply, require grounding due to the possibility of voltage appearing on the housing, and this does not indicate breakdown at all. There is nothing extraordinary in the construction of the power supply, there are simply capacitors and a potential appears on the capacitor casing. Virtually most household appliances require grounding, unless the equipment is made in the "second class of insulation" standard, such equipment is usually marked with two squares one in the other, then we have a flat plug.

Electricity, electricity is not ticking. And I am an IT specialist:]
But I guess I did the right thing. Take a look and tell me if I have succeeded:>

Just before you connect something to it, make sure that blue is zero and black is phase ...

I made sure before It would be as if I had mistaken the xd cables. Thank you for your help

Hello, I have a similar problem. The neutral wire is not connected to the pin socket. It was checked by people who measured the difference. I have a surge protector connected to this socket, a lot of electronic devices, a guitar amplifier, a computer, a radio are connected to this strip. I had a failure of the power supply for guitar effects, noni radio, Pioneer xem26 micro system, described in another thread. How do you think, gentlemen, could this failure have been caused by the lack of zero on the pin in the socket? If the cables are short, can I make a bridge with another piece of wire with a similar copper cross-section? I will be grateful for any advice. Best regards, Bartek.

Hello, they come back to zeroing the socket, does it matter if I connect the bridge from the neutral wire terminal to the pin. In a word, the neutral wire is where it was, and I make the bridge with a piece of wire. Will such a zeroing work with a difference that I think I have at home. There were gentlemen who measured it and found that the sockets in the room are not reset. The second question is whether the phase has to be on the left side. Using the ever. I had a 2nd hardware failure. I burnt the power supply for guitar effects and the Pioneer xem26 radio. I bought a great Philips strip with two protections, but the manual said that only to the zeroed socket. I will be grateful for your help. Greetings.
