Use of 4x1.5 Flat Cable YDYp Ż Instead of 5x1.5: Gray Wire as Neutral?

Question

Hello and welcome. I made the mistake of ordering a 4x1.5 flat cable recently. I needed a classic, for stair and cross switches .. Everything would be ok if I checked the colors before assembly (5 houses), and the opposite happened. So far I've ALWAYS used 5x1.5. I don't know what...

Unfortunately, I don't know anything about any contractual rules. I doubt they are. However, I often meet where the gray vein is used as a neutral. Notoriously in induction hobs with a factory-connected cable, where the gray and blue wires are pressed in one sleeve and marked with the N symbol. As you can see, you are not (will be) the only sinner.

I wouldn't touch it that way (but marked it). Worse if light blue was made phased.

rozales · Answer

Such wires are often used for lighting.

Thanks for the answers. I have never used 4x1.5 before and therefore I did not think that such a cable without N could happen to me. So this unfortunate gray can be used interchangeably, right? Are there any rules as to which of these phases to use as N?

jann111 · Answer

There are no such rules. Blue is reserved for the neutral conductor. I'll say more, light blue.

tomhorn1 · Answer

I know it perfectly well. I'm asking about this emergency situation.. I was thinking of a more conventional rule in this situation.

rozales · Answer

You certainly can't use light blue as a phase. Sometimes the cables have only black wires and then how to connect the neutral?

tomhorn1 · Answer

Thank you very much for your answers. I know, a trivial problem for such a forum, but my hair stood on end at first, as in a classic stair (I thought) cable there is no N Thanks. T

jann111 · Answer

Classically, your cable is OK for stair and cross. And if you run the power supply on the same cable as communication, then there should be 5 wires.

Does it matter which way? It's strange to read posts like this without being attacked by staunch opponents of any kind of wire marking. I personally do not belong to this group. I used to work in a country where you even have to use t-shirts when changing the function of the cable. But everyone is entitled to their beliefs....

Maybe a colleague will bring this country and these requirements closer?

I am such an opponent of marking blue and yellow-green veins as phase ones. There is only one argument against such a procedure: such a vein can kill. On the other hand, the other way around: the phase wire (brown, black, gray) connected to the neutral or earth - will not kill. There is another reason why the yellow-green wire must not be used as a phase wire: then the circuit/installation of the protective wire is deprived, and it belongs to it like a dog house ... and it is not subject to discussion. you wanted? You have!

Łukasz-O · Answer

In this case, it would be necessary to withdraw from use, for example, all self-supporting cables - popular braids, commonly used by ZE.

zbich70 · Answer

Interestingly, PN-HD 308 S2:2007 does not favor the blue color in multicore wires/cables, treating its purpose for working (active) conductors. The blue neutral color requirement applies to single core wires/cables. But PN-EN 60446:2010 clearly says that N is supposed to be blue.

Anonymous · Answer

Of course, N is supposed to be blue, PE yellow-green. No reasonable person is messing with the EP because if it is, it must stay. In GB, we most often had wires without PE insulation where you had to put on a jacket at the connection points. I am currently using these cables as well. Marking most often took place during the renovation of facilities (as-found condition) where the wires were different red and black, only black, red, blue and yellow. Especially the latter could be dangerous. There was also branding in the new installation...

I found a photo taken during the connection of cables in the switchgear and this is where the gray wire is also used as a neutral. It was done by two licensed electricians and I was just watching.

kkas12 · Answer

No electricity, but an electrician does.

e-sparks · Answer

Why could the yellow wire be dangerous? Maybe because it is the color of the L2 phase wire? Or maybe at least you know what function the black wire played in these installations? Polish wirelines were there???

Anonymous · Answer

Yellow color, although rare, did it either for protection or for a phase, not only we meet bunglers. And what does the Polish wire haulier, as you called it, have to say when he gets the material and guidelines? Go to the store, buy for your kilometers of wires and then explain to the manager that things are done differently in Poland? Added after 6 [minutes]: Question for user e-sparks, what wires would you use in a hospital building?

kkas12 · Answer

Don't write crap about bungling if you don't know their premise. Until some time, they used red, yellow and blue as phase colors. The neutral color was black. So in order to do anything there, you should first make sure what kind of installation we are dealing with and not talk about bungling. And these wires with a bare protective conductor should be introduced in Poland. Then these moronic wisdom and arguments about markers and phase T-shirts on a protective vein will end.

Anonymous · Answer

I would agree if one was made the same, and if the color used is used once for power and once for protection, it's bungling and that's it!

kkas12 · Answer

Because earlier the yellow color was a phase and today the green-yellow color is a protective conductor. You need to distinguish when what was done and not exaggerately bestow epithets. If you orac there, you have to follow their standards and not start teaching by condemning the local electricians in the head.

Sorry, you don't know what you write or you don't read what other people write. Unless, no matter what, yours must be on top. I'm done with this....

kkas12 · Answer

Is it?

e-sparks · Answer

Until 2002, in Great Britain, permanent installations (those arranged permanently) used red, yellow and blue as the phase colors, and black as the neutral. The yellow wire has NEVER been used as a protective one, the yellow-green color has always been reserved for such a wire!!! At the same time, there was another standard for flexible/flexible wires, i.e. connection wires, the same as currently commonly used, i.e. brown, black and gray as phase wires, and the neutral wire in blue. Therefore, for a Polish electrician, such a mix of colors can cause confusion: once for protection, once for power. Well, unless the wire from the Vistula River has already stuck its hands there

Akrzy74 · Answer

I propose to end the discussion about the color yellow. User markus-19 has received a warning for his moss and fern theories. If there are further posts related to the above, they will be deleted along with others (which they concern) to the trash. Colleague e-sparks has exhausted the topic. Please don't use style words . An electrician is not equal to an electrician and we know it well, but there are certain limits. Thank you for your understanding. Christopher.

tomhorn1 · Answer

It was completely nervous. This is often the case here. Pity. To sum up and going back to the beginning of this topic, I will use gray as neutral in all 4x1.5 cables where unfortunately there is no blue and mark it with a blue T-shirt, just in case. This is an absolute exception. I will be more vigilant in the electrical warehouse in the future...
