Why is everyone so critical of the Leroy Merlin cable? I decided to check and compare, I show the real result.

During the entire construction of my house, I have already managed to study and grind a bunch of information, most of which I take on the Internet. And at the same time, it is becoming more and more clear that you cannot trust everything. Your experience, it is always more convincing ...

Friends, I am glad to welcome everyone. Slowly, little by little, I am preparing for the electrical installation in my house.

And it was a revelation for me that there can be so many questions with the choice of cable.

On numerous forums, I have never once come across the topic of the fact that nowadays it is very difficult to find a cable that would correspond to the declared characteristics.

More specifically, we are talking about the cross-section of the veins, which in reality may differ from what is written on the package.

Leroy Merlin is blacklisted as usual.

This is not the first time I come across the fact that I hear bad reviews about products from this store. All three years of construction, I made a lot of purchases there, and never came across a specific marriage.

But in the case of an electrician, I decided to double-check everything.

• I already had a cable from Leroy (I bought it for the first, temporary electrician in the house).
• Now I also bought a cable in another place (which is praised by all electricians), the ETM store.

We start checking ...

For measurements, I used a caliper, and a table of correspondence of sections and diameters.

On the cable of LLC "Elprom" 3x1.5, the actual core diameter was 1.35 mm, which is very close to the required diameter of 1.38 (see the table). And then a Caliper is not an ideal measuring device, in this case.

The cable sold in Leroy is produced by Partner-Electro LLC. And he showed the result no worse.

The scale also shows a value around 1.35 mm.

Now let's check the cable 3x2.5 mm².

Here I was the first to check the cable produced by "Radius". Diameter 1.8 mm. is quite consistent with the norm (according to the table for a cross-section of 2.5 mm, the core diameter should be 1.78 mm.).

Now a copy from Leroy. He showed a result of 1.7 mm.

You can already find fault with this result, if you want. But in my opinion, this is also not critical.

What conclusions can be drawn?

It seems to me that all the disputes and conversations around cables from different manufacturers are too far-fetched. Of course, you can walk around and choose with a caliper in your pocket, but it seems to me that it is better to follow simple rules.

• You do not need to take the cross-section back to back.
• Calculate an adequate load on the cable (light - 15 sq.; sockets - 2.5 sq.)
• And use the appropriate automation (1.5 sq. - C10; 2.5 sq. - C16)
