At least one partition-type insulation barrier consisting of electrically insulating material can be allocated to at least one opening (27; 60, 61), thus increasing the clearances and creepage distances between two neighbouring openings (27; 60, 61). The insulation barrier can be fixed to the housing (11) of the installation device. ## Claims ### Claim 1 An electrical service device having a housing, in which voltage-carrying components are accommodated which are accessible via openings in the housing of the service device, wherein at least one opening can have at least one wall-like insulating barrier associated with it which consists of an electrically insulating material and with which it is possible for the air gaps and leakage paths between two adjacent openings to be increased, and wherein the insulating barrier can be fixed to the housing of the service device. ### Claim 2 (depends on 1) The service device as claimed in claim 1, wherein the insulating barrier has a wall section which protrudes beyond the outer contour of the service device. ### Claim 3 (depends on 1) The service device as claimed in claim 1, having narrow side walls and at least one facing wall and having broad side walls, wherein two depressions are provided on the broad side walls in the region of the openings such that, when two service devices are arranged next to one another in a row, in each case one gap is formed between the second depressions, which gap opens in each case towards the facing walls and the narrow side walls or opens out into them, with the result that the air gaps and leakage paths are increased. ### Claim 4 (depends on 2) The service device as claimed in claim 2, wherein the wall section is integrally formed on a support, which engages over the opening and is matched to the contour of the installation housing at least in the region of the openings, on at least one side edge of the support, which side edge is located in the region of the side wall of the installation housing. ### Claim 5 (depends on 4) The service device as claimed in claim 4, wherein the wall sections are integrally formed on each edge located in the region of the side walls such that the wall sections act as continuations of the side walls. ### Claim 6 (depends on 4) The service device as claimed in claim 4, wherein the support is fixed with the wall sections on the service device in a manner suitable for retrofitting. ### Claim 7 (depends on 2) The service device as claimed in claim 2, having a pedestal design and having one front and two rear facing walls and two front and rear narrow side walls, wherein in each case one support with the wall sections is fixed to the rear facing walls and the rear side walls adjoining them. ### Claim 8 (depends on 7) The service device as claimed in claim 7, having a pedestal design and having one front and two rear facing walls and two front and rear narrow side walls, wherein second depressions are arranged in the region of the rear facing walls and the rear narrow side walls. ### Claim 9 (depends on 7) The service device as claimed in claim 7, wherein each support is matched, approximately in the form of an L, to the respective contour of the rear facing walls and narrow side walls and—between the wall sections—has apertures, which are aligned with the openings in the housing. ### Claim 10 (depends on 9) The service device as claimed in claim 9, comprising inner wall sections provided on that side of each support which faces the service device and at least partially engage over the broad side of the service device. ### Claim 11 (depends on 9) The service device as claimed in claim 9, wherein recesses are provided on the broad sides in the region of the front and rear facing and side walls, in which recesses the inner wall sections engage, with the result that the outer face of the inner wall sections and the broad side faces lie approximately in one plane. ### Claim 12 (depends on 11) The service device as claimed in claim 11, wherein in each case one groove is arranged in the recess section, which runs parallel to the rear narrow side walls, in which groove a web engages which is integrally formed on the end edges of the inner wall sections so as to project towards one another. ### Claim 13 (depends on 12) The service device as claimed in claim 12, comprising latching means provided on the webs and in the grooves, via which latching means the support can be fixed to the service device. ### Claim 14 (depends on 3) The service device as claimed in claim 3, wherein the wall sections acting as the insulating barrier run parallel to the inner wall sections and are located within the planes covered by the inner wall sections. ### Claim 15 (depends on 1) The service device in particular as claimed in claim 1, wherein, in order to connect two adjacent service devices, spreading connector elements are provided which have a basic body section and a head, which is integrally formed thereon, having a larger diameter than that of the basic section, and in that the axially running outer faces of the basic body and of the head and the radial transition section between the head and the basic body can be inserted into a correspondingly matched opening so as to prevent a leakage path. ### Claim 16 (depends on 1) The service device as claimed in claim 1, wherein at least one moveable, voltage-carrying part of one service device is provided with the corresponding part of the other service device by means of a coupling element consisting of an insulating material, in the case of which, as the insulating barrier, a plate is integrally formed which is aligned at right angles with respect to the longitudinal extent of the coupling part and is formed in a depression matched thereto in at least one of the broad side faces, which lies opposite the other service device. ### Claim 17 (depends on 2) The service device as claimed in claim 2, being a line circuit breaker having a pedestal design and having one front and two rear facing walls and two front and rear narrow side walls, wherein in each case one support with the wall sections is fixed to the rear facing walls and the rear side walls adjoining them. ### Claim 18 (depends on 3) The service device as claimed in claim 3, being a line circuit breaker having a pedestal design and having one front and two rear facing walls and two front and rear narrow side walls, wherein the second depressions are arranged in the region of the rear facing walls and the rear narrow side walls.
