Connecting Legrand Differential: Correct Installation, Phase Conductors & Importance

Question

Is the connection of the differential in the photo correct? Should the phase conductors be on the right or left side ?? Does it matter ???

elpapiotr · Answer

The electrician will know no need to worry.

rarytas86 · Answer

that's for sure, but I would like to know them too, so please answer the question. because I found various connection diagrams on the net.

Łukasz-O · Answer

There is also a diagram on the camera. Can't you see him?

niewolno2 · Answer

What does the producer say?

rarytas86 · Answer

Legrand.
I can see the schematic and that's why it seems to be a good connection.
I'm right???
Today I found a photo of the differential connected differently on the net, so I am asking how is it correct ??

remik_l · Answer

And I think it's bad.

rarytas86 · Answer

hmmm, the connection in the drawing is wrong ???

niewolno2 · Answer

In the case of a 1-phase differential, it does not matter where you connect L and N, because in both cases the differential mechanism will work (it works on the principle of the difference of currents in the circuit, not voltage potentials). In 3-phase differentials we have 3 differential modules with a common N terminal, so there is required the designation of the N terminal.

tomix · Answer

According to art, L on the left, N on the right. Access on terminals with a fixed element (terminals 1-L, 3-N), output on terminals with an element (2-L, 4-N).

And if I want to use a connecting comb for es, I have to figure it out. Isn't it better to make your job easier?

rarytas86 · Answer

As for mycelium, that is, rails, I used it. It is enough to cut out one of the teeth and the differential will be connected according to the art. So L on the left and N on the right.

kkas12 · Answer

There is no art. There are manufacturer's recommendations, which means (or does not mean) the clamp for connecting the N conductor, so please do not create abstract art, because one person is already deceiving you, my friend tomix you introduced. This is no art.

rarytas86 · Answer

Well, maybe not the art, but everywhere I put the phase wire on the left.
From what my colleague writes, the difference in the picture is correct, right?
In a single-phase connection, a differential that has no marking for N connection does not matter from which we connect the phase and which N. I understand well ???

niewolno2 · Answer

If you have any doubts, it is enough to call the manufacturer or sales representative and that's it.

remik_l · Answer

Buddy, in your drawing, you have marked the phase wire and N, but you have not given where the power is plugged in and where the drains are. If so, I connect the RCD, will it be okay?

rarytas86 · Answer

On the website and in the technical specification, I also did not find where N is to be connected and where the phase.
Therefore, I am asking you for advice.
I understand that in this case the side on which the N wire is installed is indifferent?
Top supply according to the current flow diagram which is on the differential.
Why do you think it should be alternating as described in the picture?

remik_l · Answer

I did not write that it should be alternating, but I asked if it would be good if I connect it in this way, because it did not follow from your drawing.

I asked this question so that you would learn something, not because someone said so.

serwisor · Answer

Gentlemen, no one has asked the question yet:
What is the network layout you want to connect this camera to on the circuit?
What protection is against and what is behind this RCD.

How did you measure your PE? Did you even measure? There is PE at all?

BILGO · Answer

Are you sure ? In my opinion what you write is not true. In RDC 3f, the N line is only marked because it is the first to be connected and the last to disconnect
