Abstract: A short circuit test device includes: a first line test conductor couplable to a first load line conductor of an electric load network and a neutral test conductor couplable to a neutral conductor of the electric load network; a voltage source switchable to the first line test conductor and the neutral test conductor to output a predefinable test signal; a measurement unit for measuring an electric voltage and/or current, the measurement unit including measurement inputs which are connectable to the first line test conductor and the neutral test conductor, the measurement unit including an output for providing a measurement signal; and a control unit connected to the voltage source and the measurement unit, the control unit: causing the voltage source to apply a test voltage to the first line test conductor and the neutral test conductor and comparing the measurement signal provided by the measurement unit.
