    Gentlemen, how do you find out which phase is L1 and which is L2 without access to a power source?

    How do you find out with access?

    After the markings on the device, although the farther from the source it does not have to be true at all.

    And how do you compare which L1 is at the beginning and end of the line?

    Watching dog poop change colors? :D :D
    More seriously, the order in the colors is supposed to look nice.
    It would probably be nice if everyone strictly adhered to the colors, looking at the box or switchboard, you would know what is what, and you have to check it every time.
    Which is L1 or L2, it is not important on the object itself, it is given the designation L.
    It is important that the black is the same phase on the whole object as with the other colors. Then, when connecting single-phase outputs, you would know to connect the first to the black, the second to the gray, etc.
    We are used to the mess in colors and it does not matter to us, we can evenly distribute the loads of the phases regardless of their colors.

    Hi

    Norms are norms - probably none of them regulates this, but those who are willing can look for it when they have access.
    Attached I have a photo of the plug with descriptive markings and colors. Earlier, my colleague kkaz12 gave examples of documentation from Ireland ...
    I would connect as in the picture of the plugs.

    We also have a mystery how the power cord is led in the e-chain(R) and the wire markings: 4 black items numbered 1-4 and the Ż-ź wire. Someone something?

    And so, out of curiosity, I will ask how colleagues connect the emergency luminaire on a 4-core cable, what color is the neutral wire? Gray with a blue T-shirt at each end?

    Or use a 4-wire cable with a blue wire ;)

    At the very beginning, when I did the "first time" at the construction site, the foreman taught me from the darkest one, i.e. black. Later, as I generally did in other works, I start with brown, which is generally the same as the order in 5-wire flat cables.

    Hello,

    I just wanted to mention that l1 black l2 brown l3 gray makes sense if we are looking at a phase shift. l1 shifted left, l2 middle, l3 shifted right. If we look at it this way, it makes sense.

    I was taught the alphabet
    L1: brown
    L2: black
    L3: gray
    In Germany, when I did, the same order was valid and I liked it. Doing according to our alphabet makes sense here

Topic summary

The discussion revolves around the color coding and connection order of conductors in a five-core 3-phase power cable and switch cabinet. Users share their experiences and standards, noting that while there is no universal standard for the order of colors, common practices include connecting L1 to brown, L2 to black, and L3 to gray, particularly in Germany where standards like DIN VDE 0293-308 are referenced. Some participants emphasize the importance of maintaining consistency in color coding for effective load distribution and phase identification, while others highlight the lack of regulation in certain regions, leading to varied practices. The conversation also touches on the significance of phase identification in ensuring proper operation of 3-phase devices.
