    Hello
    I have a problem, I need to safely connect the device - wheel balancer. There is a clear inscription 400v on the casing and a 4-core connecting cable yellow-green with a transition to the housing brown pink and blue. In the manual there is only information about the three phases P1 P2 P3 and Pe without colors And here I have a problem because the electrician connected blue as one of the phases and now I am afraid to turn on the engine. Is this the correct connection? Regards, Przemek

    If the electrician connected so, let him start the device.
    And if the mechanic folds the timing, he gives the car to the customer without checking and in the event of the belt breaking when the engine is started, does he complain to the customer or repair what he screwed up?
    I don't know what device you have, but in Poland the blue color means N, i.e. the wire from the transformer's neutral point. It can be used in a 3-phase unbalanced installation.
    It is to be connected as written in the DTR.

    I know that blue is N and that's why it does not suit me, but I also doubt that it would be two-phase. The wheel balancer has been in stock for several years and no one remembers it working at least once. It is Dutch production and there is a diagram without color marking P1 P2 P3 and Pe no N marking, original cable but Polish plug.

    Just an electrician used a 4-wire cable with the colors blue, z-ż, brown and black to power the machine,
    Unfortunately, in this case the blue-colored conductor "does" to phase.
    And it is enough to measure the tensions between all the veins and you know everything.

    I would say resistances because if I understood correctly it is a device cable.

    Hello, this is the original cable I have met more than once that the blue cable is a phase, there are machines from other countries.

    It is correct, because the supply voltage itself indicates three-phase. Colleague @ michal54_87 he saw it rightly. Just unscrew the cover of the electrical box in the machine and make sure. L1, L2, L3 and PE (sometimes UVW, sometimes RST, but always three) + PE, i.e. protective conductor.

    In other countries it may be so, but with us it would be worth sticking to the fact that N is blue

    It is a cable for special applications, also produced in Poland. Ask the manufacturer why it was used in this case.
    In Poland, he can also be found where he should not be.

    Well, when we have such a conductor / cable, we put neutral in blue and the phase in yellow-green or neutral in yellow-green in the phase blue? The standards do not say anything about it, and how does it look in practice? How we are supposed to have only a protective one, it is known.

    I associate such a cable with induction kitchen hobs. L1, L2, N, PE for the heating plate, and L3, N, PE for the oven.

    The manufacturer gave such a cable for the compressor due to economy, unfortunately he does not have standards somewhere, and probably it was made in China

    You see, 4x cables with gray conductor are not available for motors, and for lamps with blue conductor :D

    but the Polish plug


    Since the cable is terminated with a plug, why do you go through this machine :?:
    if the markings you gave are correct, the machine is definitely 3-phase, do not be influenced by the colors of the wires

Topic summary

The discussion revolves around the safe connection of a 400V wheel balancer using a color-coded 4-wire cable. The user expresses concern over the connection made by an electrician, specifically regarding the use of a blue wire as a phase instead of neutral, which is standard in Poland. Various responses highlight that the blue wire can indeed be used as a phase in certain applications, particularly for machines from other countries. Participants suggest verifying the connections by checking the electrical box for proper phase identification (L1, L2, L3, and PE). The conversation emphasizes the importance of adhering to local wiring standards and the need for caution when dealing with electrical setups.
