1. A device for generating energy and distributing electrical energy to a plurality of electrical loads, said device comprising:

  • a distributor unit containing a plurality of distributor connector part halves;

    a plurality of pairs of lines for connecting said plurality of electrical loads to said plurality of connector part halves wherein said lines have respective first line and second line connector part halves arranged at a respective first distributor unit end and load end of said lines, wherein said second line connector part halves arranged at the load end of said lines are connected to respective connector load part halves of said plurality of loads;

    a diagnostic circuit having a line section wherein said line section is at least one of open and closed by line bridges of said first line and second line respective connector part halves arranged on said respective pairs of plurality of lines;

    a switching device actuated by a control unit wherein said switching device is arranged between an energy-generating unit and said distributor unit; and

    a signal generator and an evaluation unit functioning in association with said diagnostic circuit, wherein a diagnostic signal (u1, u2) is fed into the diagnostic circuit and at least one of a measured and calculated value of the diagnostic signal (y1, y2) is determined by the evaluation until, and wherein a fault state is diagnosed if a deviation of a determined value of the diagnostic signal (y1, y2) from the original diagnostic signal (u1, u2) exceeds a predefined tolerance threshold, and wherein a fault state is diagnosed if the diagnostic signal (y1, y2) does not change sign in a specific time interval.
