Can be used.

  In the wiring device of the present embodiment, the second outlet device 20 includes a storage battery 27 that stores the power input from the first connection unit 22, and outputs the power stored in the storage battery 27 from the second connection unit 24 to the outside. You may make it do (refer FIG. 5).

  Thereby, the electric power input from the air conditioner 6 to the wiring device 2 is temporarily stored in the storage battery 27 of the wiring device 2, and the electric power released from the storage battery 27 is supplied to the wireless terminal 4, so that the wireless terminal 4 is stable. Power can be supplied.

  Further, as shown in FIGS. 1 and 3, the wiring system of the present embodiment is connected to the plurality of wiring devices 2 described above, the first electrical equipment (air conditioner 6) connected to the wiring device 2, and the wiring device 2. The second electrical device (wireless terminal 4) is provided. The electric power generated by the first electric device is supplied to the second electric device via the wiring device 2.

  Thereby, since the 2nd electric equipment connected to the wiring apparatus 2 can be operated with the electric power which the 1st electric equipment generated, the function with which the 2nd electric equipment is provided can be added. In addition, since it is not necessary to construct a wiring for supplying power necessary for operating the second electrical device in the building, the cost for constructing the wiring in the building can be reduced.

  It should be noted that a wide variety of different embodiments can be configured without departing from the spirit and scope of the present invention, and the present invention is not limited to a specific embodiment.
