14 In a device for tapping electric voltage from an electric three-phase cable at a central distribution station (15) with a main fuse and a holder (17) therefor each phase, each main fuse holder (17) has two contact members adapted to be electrically connected to each other by a fuse inserted in the holder for electric interconnection of the parts of the phase conductor in question located on each side of the fuse and connected to a respective contact member. The device comprises two contact elements (1) adapted to be inserted into a main fuse holder (17) each, beforehand released from the main fuse, into a position in which they are in electric contact with only the first one of the contact members (18), namely the one being connected to the part of the phase conductor in question which is still under voltage when the fuse is removed, and means (2, 19) for holding the contact elements (1) in this position for tapping the voltage existing between the two phase conductors in question.
