The present invention is a digital electric multi safety control system that prevents electrical accidents that lead to the occurrence of fires, etc., in electric power apparatuses, such as switchboards, distribution boards, lighting panels, control boards, and junction boxes, which are electrically connected via, inter alia, an electrical device in which a power supply-side circuit from the power supply side and a load-side circuit leading to a load are provided in a housing. The digital electric multi safety control system further prevents the occurrence of accidents such as damage to various electric-power/electrical devices/apparatuses to which the load-side circuit is connected. The invention comprises a power supply switch control means that outputs a power supply start signal to one among first electric power apparatuses so that instead of the first electric power apparatus receiving input of the power supply cutoff signal, electrical power is supplied to a load that, when the power supply cutoff signal has been outputted to the one among first electric power apparatuses, receives the supply of electrical power from the first electric power apparatus that receives input of the power supply cutoff signal.
