Connecting the PE earth electrode from the whole house to the lightning strip.

Electrical installers in the house (shell) connected the earth electrode from under the fuse box to the lightning strip, which goes into the ground.

Is it normal and safe? What is the potential PE that will also appear in the lightning protection system on the roof, or maybe it will fly into the ground because it will be closer to it?

Shouldn't the earth electrode go on a separate hoop?

Will the lightning strike the lightning strike fly into the house through the PE conductor connected to the lightning protection system?

I do not know if my colleague described it well, but it should be like this: equalizing wire (hoop iron, copper wire with green and yellow insulation color) from the main switchboard with protection, connected to the GSW (Main equalizing bus in the building). And this should be earthed through the earthing conductor to the edge in the ground or to the foundation earthing, to which the discharge conductors of the lightning protection system are also connected.
Is that so?
If so, then that's OK, the lightning strike will be minimized via the ground and through the surge protectors in the building.

?

... where is the fuse box installed?

Maybe ... this way?

Strange my post has disappeared.

I will try to explain it differently.

The main fuse box is in the vestibule - the entrance to the building, right behind the wall there is a lightning protection system that goes to the hoop and then to the ground through the spire. The PE conductor (green and gold) comes out of the fuse box, which goes through the wall to the outside and is screwed to the lightning protection deductor.
The lightning protection system descends to the ground from the roof on two opposite sides of the building and on one side the PE from the box is connected.

The cooperage is not connected to the foundation reinforcement as shown in the picture above, but to a 2m spire driven into the ground.
In other words, the earth electrode of the building's electrical system is connected to the lightning protection system.

If I somehow connected the voltage to PE, the current would either go to the ground through the spire, or it would go to the roof Although in theory it should fly to the ground, choosing the path with the least resistance.

In theory, the current is DIVIDED and flows in both ways. Another thing is you are mixing voltage and potential with current.

Share the current and take the path to the ground on the opposite side of the building instead of going straight to the ground where it connects to the hoop 20cm above the ground?

Am I confusing the concepts? If there is a sufficient potential difference, current will flow. If I connect 100V to PE and PE is grounded to the ground, the current will flow, probably?
But I am not asking for definitions or nomenclature.
But out of curiosity, where do I confuse electricity with voltage?

Only if it is safe to connect PE to the lightning protection system, or if it should be connected to a separate hoop (separate from the lightning protection system) which is connected to the spire driven into the ground.

Do I understand correctly? The lightning protection system does not have one earthing (ring), but a separate one for each exit? This is not the happiest solution. The PE of the electrical installation is to be connected to the lightning rod earth electrode, but one that ensures a certain equipotentiality of the building. Two separate lightning rods provide this on average. In addition, the connection of the electrical installation with the lightning protection should be directly through the earth electrode, not the discharge wire.

Hello,

yes, there is no hoop around the building to which the exits from the roof are connected. But I talked to many lightning protection installers, and each of them objectively said that the spiers are sufficient, but this is confirmed by measurements. I think both spiers have the same potential.

Therefore, in my case, two exits from the roof enter through a spire stuck 2m deep, about 4m from the building wall.

Am I to understand that there are two drain wires and only one ground wire?
If so, then read p. E.5.4.3.3 Type A radial and vertical earth electrodes in PN-EN 62305-3 .

Here http://ochrona.net.pl/pdf/uziomy_w_ochronie.pdf I read about the nomenclature and like this:

I have two discharge wires which, through the control junction, are connected with the ground wire and enter the vertical earth electrode (my spike).

So I have vertical earth electrodes, not connected to each other. And the building PE conductor is connected to one of the control connectors.

Thank you gentlemen for the interview - lightning is not finished, so I can still introduce some corrections

The grounding of the PE conductor through the connection with the vertical earth electrode of the lightning protection system should be performed below the ground surface and at the control junction of the lightning protection system.
Since you are asking about possible corrections, start with a professional lightning protection design.
There would be no topic if you asked before execution, not after.
The basic question is: Where is the foundation earth electrode?

Now it is just "repairing" a mess that did not have to be and which cannot be completely repaired in this way.

Hello.

According to the regulations each discharge conductor should be provided with an earth electrode. . Someone may suggest that he is

This is not a good solution, especially since step voltages should be controlled by appropriate equipotentialization, but this applies especially to vertical earth electrodes located around the building.

After all, how? How is this lightning conductor in the design?

The greatest risk may arise when the lightning discharge through the discharge pipe is discharged to the ground. Then there is a risk of lightning being introduced into the building.

For this reason, it is unacceptable to connect the PE conductor from GSW with the conductors leading off the lightning protection system above the ground.

@elpapiotr
I don't know how to describe it easier.

After all, I wrote that EVERY of the two outgoing wires has a vertical earth electrode.
So both quotes confirm one fact.
I do not have a lightning protection designed in the project. Neither are the foundations grounded.

@kSmuk
In that case, I will set up an additional third earth electrode for the PE electrical system from the building.

And what you included in both quotes is in line with the design of the lightning protection system?

I do not have a lightning protection designed in the project.
Neither are the foundations grounded.

In the project he writes "the switchgear should be earthed to a pipe earth electrode, the value of which cannot exceed 10Ohm

What are you doing it for? On what basis will you write the certificate of the lightning protection device that I will not mention the test report?

Well, check out the Journal Of Laws No. 75, item 690, where in § 184. 1. of the known regulation, he writes what your "designer" did not deign to notice.

Why am I doing? Because it is a house with an inhabited attic and I would like to have some additional level of protection. As far as I know, the metric is made by the lightning protection installer.

In the project he writes that according to the standard, if the lightning hazard index is lower than W =

And what this installer will enter in point Name and address of the body that drew up the project ? Will he design and make himself?
Design permission has?
PS. What is your friend's lightning hazard rating?

And if you are making a lightning protection installation, even though it is not included in the project, why did you not make a foundation earth electrode?

@elpapiotr
Of course, it has powers to make and design.

And the threat index? As I wrote above, he does it for his peace of mind.

@ kkas12

Because I had no idea about it, because there is not a word about it in the project.

Now I understand that the lightning protection installation will be made in accordance with the requirements of Polish Standards regarding the lightning protection of facilities
construction because that someone

It's just somehow strange ... this project is being created.
Perhaps the peasant ("designer") is just learning.

I am asking my colleague, at the end of the works, to attach the project, metrics and test protocol. After all, I will also be happy to see the photos.

After all, there is not always an opportunity.

@elapiotr
Please abstain from irony and discharge your sense of humor somewhere outside the forum.

Having diplomas, cups, medals, certificates and licenses does not prove anything.

Therefore, I wanted to dispel my doubts here on the forum.
But I can see that it will not work. Although at the beginning there were hopes for it :)

I have PE separated from the earth electrode with a surge arrester.

You just wanted to hear confirmation of what you yourself think. Lack of confirmation is not so much satisfying ...

Absolutely not.

As mentioned above, I am in the process of doing this installation so I can change a lot.
I do not prove the correctness of the connection made by me.
I just want to know if it is wrong and know why and how it should be.

I only know that it is best to make a ring earth electrode to which the exits from the roof should be connected, and the PE connected to the foundation earth electrode.

Not at all. In the case of a correctly made foundation earth electrode, the ring is unnecessary.

We understand the foundation earth electrode only as a hoop connected to the reinforcement of foundations / continuous footings or as a horizontal or vertical earth electrode?

Fundamental it will not do. He can make a ring and connect the drain wires and the PE wire to it.
