Choosing the Right Cable for WLZ: 4 or 5-wire, Tauron ZE Box, YKY 5x16mm, TN-C Transformer

Buddy, plug in two 16mm? wires.
It's stucco, regardless of the cross-section.

AROT is a kind of conduit after all? I think 40mm.

Maybe for you. For us, Arot is Arot and the barrier is the barrier.
If you have a conduit, you will most likely end up breaking the pipe if you do not skilfully prepare the cable for retraction.
And the 40mm diameter is also a butt joint. Even for Arot.
I hope this saving doesn't hurt you.

I don't know if it is 40 or 50mm, but it really goes in a straight line, do I know if savings, they said how they would do and I agreed to it, how should it be otherwise?

And we still don't know what you've got

Only that it does not turn out that you will not pull the cable in the conduit or whatever you have there, and you will have to make a new trench for the cable you have purchased.

Arot is a company name and not a pipe of any kind. A friend has already bought a YKY 4x16 mm? and good, maybe someday it will increase the power (a more powerful car charging station?) It will be.

Hello,

I need to perform an WLZ, i.e. plug the house into the ZE box (Tauron, if it matters).
And now like this:
- the transformer works in TN-C, i.e. in the box I have 3 phase terminals (Etimat T) + a single blue terminal for N.
- in the construction project, it is necessary to make WLZ YKY 5x16mm?.

What to do with the PE conductor, if I actually do WLZ 5x16mm??
- can make 4x16mm??
- leave the PE free and not clip in? (apparently ZE can attach)
- or maybe, as a friend told me, make N and PE as 1 wire and connect as N?

The connection should be made in accordance with the design. If there is a suspicion that there is a mistake in the design, the design should be returned to the designer for checking and correcting it. Only the designer has the right to improve the design. The designer will answer your questions why this and no other cable has been used and will dispel your doubts.
These are simple and well-known rules.

What off topic, and there was a question whether 4 or 5 were alive.

The construction manager can make changes to the project, and he actually does the majority and then runs the entire construction until the end.

The site manager has the appropriate permissions to make changes to the project?

The site manager was designing the electrical connection?

Well, unless the regulations have changed and the manager has the authority to make changes to the project. As the regulations have changed, maybe colleagues more familiar with the subject will confirm it.

Colleagues, leave the project topic alone. The author bought what he bought and it will stay that way.

Let me revive the topic because this week I was a participant in a conversation with an "inspector" from ZE during the supply of voltage (installation of the meter) to the facility. TT overhead network, pole measurement, 4-core WLZ earth cable for the powered building.
Inspector - well TT is here so 4 wires are enough. But when we modify it on TN-C, it cannot be used because it does not have 5 wires.
Electrician - why?
Inspector - because our PEN conductor from the pole must be separated in front of the meter into PE and N.
Electrician - why can't there be PEN all the way to the facility?
Inspector - because the meter is a separable element, it breaks the continuity of the wire and it can no longer be treated as a protective one.

What do you say to this argument? The measuring and junction box (from the supplier) actually has a PEN conductor (from the pole) connected to the mini rail with the output to the meter, functional earth electrode and one more "eye". Apparently on the recipient's PE.

I am asking for calm answers.

Kind of right, but there are probably several such connectors on the way from the transformer to the PEN meter. The PEN counter will not disconnect. Except for damage to the clamp. But that could happen anywhere in front of the counter.
The second thing. If I have a switchgear located 60 meters away from the junction box, the 60 meter PE will work well?

IPZ on the way L-PEN WLZ 4-wire is probably the same as for L-PE WLZ 5-wire?

This is not an argument. This is probably a continuation of the self-proclaimed dream of the prince of ZE.
And if he is so "smart", let him disconnect the power supply to all objects where zeroing is the means of protection against electric shock.

This pseudo electrician probably did not see a diagram of the meter.

Something called him, but he didn't know where. Probably the saying "who breaks PEN has no reason", but the bidak did not associate that it is about connectors, fuses, not strips, terminals etc.

Whole life with crazy people

Taken for 4x16, the cable went through without a problem, Tauron sealed the box to the end, nobody stuck to anything, everything works as it should. ;)

I was afraid that they would attach to this little stock that I left in this sort of compartment under the "chamber" with a meter, but they saw and said nothing.
