On the other hand, a smart distribution panel which allows the user to confirm the usage amount of the branch power in recent years has been variously released as shown in FIG.

FIG. 1 is a configuration diagram and an installation state diagram of a conventional smart distribution board in which an AC power source is supplied to a distribution board 10 via an electronic strategy meter 40 and a distribution board 10 receives an integrated power usage amount through an electronic watt- And each electric power consumption of the line branched to the rear end of the distribution board 10 is measured by a current transformer 20 and transmitted to the multiple power meter 30, The branch power consumption can be displayed.

However, since a conventional distribution panel is not only complicated in wiring but also has a very narrow internal space, there is a limit in the number of current transformers 20 that can be connected to the multiple power meter 30, .

On the other hand, recently, a smart home distribution board capable of monitoring the power consumption and controlling the power supply amount, such as Korean Registered Patent No. 10-1295843, has been developed.
