Noob nucler wiring HELLLP

    i have cables running into a mfsu then a cable going to a LV-transformer
    but it blows up what should i do to be able to power my machines with
    it? am i putting the wiring in the right spot? or am i not using the right cable/tranformer?

    You have to connect the mfsu to a MV-transformer before the LV-transformer.
    LV-transformer can receive only 128 EU/t but the mfsu sends packets of 512 EU/t.
