Summary:PURPOSE:To make it possible to perform a switching from an existing power source to a new power source without power service interruption by connecting a shunt equipped with an reactor for suppressing a rush current and a contactless switch being conductive after receiving a conducting command signal between newly installed power supply terminals and load terminals. CONSTITUTION:A first switchgear 15 connected between an existing power terminal 2 and a load terminal 4 is provided, and connected state between these terminals 2 and 4 are opened. Also, a second switchgear 16 is connected between a newly installed power supply terminals 3 and the load terminals 4, and these terminals 3 and 4 are connected together after the make and break of the first switchgear. Moreover, a contactless switch 17, a rush current suppressing reactor 18 and a third switchgear 19 are arranged in parallel to the second switchgear 16 between the newly installed power supply terminals 3 and the load terminals 4 thereby forming a shunt. By doing this, the switching from the existing power supply to the new power supply can be performed without power service interruption.
