PROBLEM TO BE SOLVED: To reduce the man-hour and the cost in a power source control unit having an electric leak protecting function.;SOLUTION: This power source control unit comprises an electric leak cutting-off part 14 for cutting off a power source line by detecting the electric leak at a load side, a power source part 15 to which the commercial power is supplied through the electric leak cutoff part 14, and a control part 16 for performing the desired control operation by power supplied from the power source part 15, and the electric leak cutoff part 14, the power source part 15 and the control part 16 are built in a single case (case body 18a). Preferably, a group of components 14a constituting the electric leak cutoff part 14 are mounted on a base 15b (16b) same as that on which a group of components 15a (16a) constituting one or both of the power source part 15 and the control part 16 are mounted.;COPYRIGHT: (C)2004,JPO&NCIPI
