ABSTRACT:
An electrical distribution device with preventive checking of the state of the load, particularly for civil and industrial users, having a plurality of electrical tapping outlets which are mutually connected by a single-phase/multiple-phase electrical distribution line and at least one electrical connector for data transmission which is connected to elements for controlling the device. Each outlet is provided with elements for detecting plugs within the respective receptacles; these elements indicate the presence or absence of the plugs to elements for connecting the outlet to the electrical distribution line; each outlet is also provided with elements for detecting phase
eutral polarity and elements for detecting the state of the load. The connecting elements selectively close normally-open coupling elements between the electrical distribution line.
