Abstract
When a power source-side electric path from a power source side and a load-side electric path directed toward a load that operates with power supply, a receptacle serving as an electric connection portion for supplying power to the load are electrically connected to each other via a power device, the system automatically performs ON/OFF switching of each of the loads, automatically checks a meter for a power usage amount in the load and automatically calculates the power usage amount to save labor, and further prevents occurrence of an electrical accident leading to a fire by, for example, detecting bolt looseness in a bolt screw tightening connection portion in the power device, insufficient insertion into a receptacle, and leakage due to dust adhesion in the bolt screw tightening connection portion.
