<p>The present invention relates to a distribution network comprising electric wires (5) for distribution of electric current, a plurality of tap-off facilities (6) with at least one socket means (9) for tapping off electric current to optional power-consuming units (1), and a central computer unit (10) communicating with the individual tap-off facilities. At least some tap-off facilities (6) in the network comprise a switch (13) and a regulating device (11) with a microprocessor (21), a user connecting a power-consuming unit (1) to one of said tap-off facilities being identifiable to the central computer unit (10) or to the regulating device (11) via a microprocessor in the power-consuming unit, and the regulating device, in case of accepted identification, keeping the switch (13) closed and permitting tap-off of electric current from the socket means (9), whereas, in case of non-accepted identification, the regulating device keeps the switch open and prevents tap-off of electric current from the socket means (9). The invention also relates to a device and a method for respectively permitting and preventing current supply from the network.</p> |
