Accordingly, current cannot also be applied to the energization check circuit 230 electrically connected to the power terminal 210 . For this reason, the buzzer and the LED lamp connected inside the energization check circuit 230 may also not operate. That is, when the energization of the corresponding room is not normally performed, the buzzer and the LED lamp inside the tester device 200 do not operate, and through this, the inspector can determine that the energization of the corresponding room is not normally performed.

As described above, according to an embodiment of the present invention, a tester device is connected to the outlet of the corresponding room in order to check the power supplied to each room of the building, and when the power is normally turned on, it is notified through a buzzer or an LED lamp so that the inspector is energized It is possible to realize a energization confirmation system and method that enables confirmation of whether or not there is.

Those skilled in the art to which the present invention pertains should understand that the present invention may be embodied in other specific forms without changing the technical spirit or essential characteristics thereof, so the embodiments described above are illustrative in all respects and not restrictive. only do The scope of the present invention is indicated by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included in the scope of the present invention. .
