Abstract

The electric leakage protection device (feed control device includes an electric leakage detector, an electric leakage protector, and a self leakage generator. The electric leakage detector outputs an electric leakage detection signal when a current leaked from a main circuit exceeds a threshold value. The electric leakage protector opens a contact device interposed in the main circuit when receiving the electric leakage detection signal. The self leakage generator includes; a first short circuit having a first electric resistance component and a first switch component electrically connected in series with each other, and a second short circuit having a second electric resistance component and a second switch component electrically connected in series with each other. The first short circuit and the second short circuit are electrically connected in parallel with each other with regard to a pair of power supply paths constituting the main circuit.
