An apparatus for electric power distribution

An apparatus for electric power distribution, comprising an enclosure (102) having an access opening (104) and defining an interior space (106), at least two electrical components (214, 314, 414, 218, 220) for separate phases of electricity within the apparatus, the two components being located within the enclosure and being spaced laterally from one another, at least one barrier panel (120, 122) formed of an electrically insulating material, the barrier panel being movable in relation to the enclosure between at least two positions, and guiding means (124) for guiding the barrier panel between the at least two positions, the guiding means being adapted to guide the barrier panel to a working position in which the barrier panel is located within the enclosure and between the components (214, 314, 414, 218, 220) and is adapted to provide a barrier between the components. The guiding means (124) are adapted to guide the barrier panel (120, 122) to an access position in which the barrier panel is located within the enclosure and displaced from the components in relation to the working position of the barrier panel, and in that the barrier panel is adapted to provide access to the at least two components (214, 314, 414, 218, 220) when the barrier panel is positioned in the access position. A metering panel for medium and/or high voltage comprises the apparatus.
