The invention relates to a switchgear with a bus bar connection device having reduced constituent parts. The bus bar connection device has a first bushing (9) with an internal stem conductor (12) whose end is a first connection surface (12a) stuck out of a nose (9a) of the bushing. The bus bar connection device has a second bushing (10) with an internal stem conductor (16) whose end is a second connection surface (16a) stuck out of a nose (10a) of the bushing. The first connection surface (12a) of the first bushing (9) is placed opposite the second connection surface (16a of the second bushing (10), the axis of the first bushing being identical to the axis of the second bushing. The bus bar connection device has a connection element (8a) electrically connecting the first connection surface (12a) with the second connection surface (16a. The bus bar connection device has a cylindrical insulation adapter 10 surrounding the nose (9a) of the first bushing (9), the nose (10a) of the second bushing (10), and the connection element (8a) as one.
