  However, each of Patent Documents 1.2 is a table tap, has a number of outlets, and has a switch corresponding to each outlet, and issues an alarm when a measured value exceeds a set value. However, the current of the device in use is not automatically cut off only by a warning, and if there is no person near the table tap, the current exceeding the set value is flowing. However, the one in Patent Document 3 is an outlet, which has a plug pin projecting through a socket of a commercial power supply on the lower surface of the housing and a display unit on the upper surface. It was only a display of the position of the outlet and the lead socket, not the display of.

By inserting the plug attached to the device or the plug of the connected table tap or the like into the plug insertion port, it is possible to know the power in use, so that it can stimulate power saving and contribute to power saving. Since the breaker switch that shuts off the circuit when the operating power calculated by the arithmetic circuit exceeds 1500 W is provided, the circuit breaks off when an overcurrent flows, and the overcurrent exceeding 1500 W during a lightning strike is also used. It is safe to prevent electric current from flowing into the electrical equipment.In addition, it has a notification lamp that repeats flashing when the breaker is shut off, so that it can immediately know the shut-off state, and it is an innovative and highly practical device. is there.
