A plug-in device enclosing Ai (Artificial intelligent) and IoT (Internet of Things) and a method for linking AC wiring devices and AC loads via cascading optical grid for exchanging at least one of two way communication through the optical cascading grid, enabling to introduce and assign AC switches and AC outlets and link optically the entire electric device of a residential and commercial units and communicate the power consumed and the loads statuses, at all time, and limiting the WiFi communication to a single transmitter at the time, to ensure no error communication.

A power distribution system includes a track having a first end, a second end opposite the first end, and a longitudinal axis extending through the first and second ends. The track defines a channel extending along the longitudinal axis. A plurality of power cables is positioned within the channel. A electrical hub is movably coupled to the second end of the track. The electrical hub is electrically connected to the plurality of power cables and includes a power receptacle. The electrical hub is movable relative to the second end of the track to change a position of the power receptacle relative to the track.
