Abstract: An electrical service distribution board is accommodated in a housing, has a feed conductor that is inserted into the housing and has outgoer conductors that lead to individual loads. Electrical service devices with different protection tasks, such as fault current protection, short circuit or over-current protection and the like, which can be connected to the feed conductor and to the outgoer conductors by a plug connection via a connection system which contains connection conductors connected to them. A mounting plate is providing for holding the service devices, with the connection conductors disposed underneath the mounting plate and the mounting plate having openings into which plug elements which are disposed on the service devices can be inserted.
