    I have such a problem namely I am trying to connect a wood splitter it has a 5 pin power plug and I have a 4 pin socket and no matter how I combine it knocks out the protection and the motor buzzes I have connected the ground and N together each separately I have swapped the phases and the effect is still the same what could be the problem?

    Hello
    In a 5 pin socket you have 3 phases L1, L2, L3 and N and PE. You need to connect N and PE together and give the PEN wire in this place. Phase wires in their place (that is, L1....).
    Be careful!
    Check that the housing of the device is connected to the PE of the plug.

    If the device is powered only from the 3x400v network and nothing else is supplied on it from the 230v network, then the blue N wire should be insulated and left free in the plug.Then you connect 3 phases L1 L2 and L3, and the protective wire yellow-green wire is connected to the thick pin with the word PE If the device is switched by a contactor with a coil with an operating voltage of 230v, then the coil should be replaced with an operating voltage of 400v by connecting it properly.

    When in doubt, ask, don't experiment.

    maybe the fault lies precisely on the side of the coil I have to check it

    If there is no ground fault circuit interrupter in the circuit of this socket, then you connect the N blue wire together with the protective conductor under the thick pin marked PE or PEN.

    I'm not an expert, but it seems to me that such a switch could be there, because when I turn on the engine, it makes a noise and the power is automatically cut off.

    Hello
    What can buzz when the protection knocks out ? After all, there is no voltage on the motor.
    And besides, what goes off - the differential or eski ( fuses - current protection ). Because if there is a differential then you can not connect the neutral wire with the protective - N with PE.

    at the time of pressing the switch the motor buzzes and blows the fuses I let go of the button the buzzing stops but I have one phase blown

    Added after 2 [minutes]:

    whether to connect PE and N wires together or one or the other

    And what wattage is this motor and what fuses (should they be of the same value on each phase)?

    protection is 25A motor about 3kw

    You did not answer the questions of colleagues "is there a differential?"
    If there was a 4 pin socket so far then probably there is no differential, but write how it is in reality.
    And the motor is connected correctly (star, delta)?

    1. no phase in the socket ???
    2. a gap between the plug and the motor ???
    3. can the motor shaft be turned by hand ????

Topic summary

The discussion revolves around connecting a wood splitter with a 5 pin power plug to a 4 pin socket, leading to issues such as motor buzzing and circuit protection tripping. Key points include the necessity of correctly wiring the phases (L1, L2, L3), neutral (N), and protective earth (PE) connections. Users emphasize the importance of not connecting N and PE together if a differential circuit breaker is present. The motor's specifications, including wattage (approximately 3 kW) and fuse ratings (25A), are also discussed, along with troubleshooting steps like checking for phase presence, ensuring the motor shaft can turn freely, and verifying the connection type (star or delta). Recommendations include consulting an electrician for resolution.
