Abstract: A power cord includes a plug. The plug includes plural blades to be respectively inserted into plural blade insertion holes of an electrical outlet for connection. The plug further includes plural thermal sensors provided so that each of the plural blades corresponds to a thermal sensor. The power cord further includes a communication circuit that is configured to notify a control circuit of a load, when a temperature detected by any one of the plural thermal sensors is higher than a predetermined temperature.

Abstract: A power cord includes a plug and a load connection portion connected to a load. The plug contains a plurality of plug pins which are respectively inserted in plug pin insertion holes of a power socket and connected to the power socket and a plurality of PTC thermistors, at least one of which is provided for each of the plug pins to detect a temperature of the corresponding plug pin. The PTC thermistors form one series circuit, and the power cord includes a shut-off device which turns off power supply to the load connection portion from the plug pins when a resistance value of the series circuit is equal to or higher than a predetermined value.
