• the invention solves this problem by the subject matter of claim 1. It also provides the subject matter of claim 16.
• the invention is characterized by a designed for direct contacting of the busbar of one of the terminal blocks or for contacting conductive elements of the cross connector test plug. Since the test plug can be placed either directly on the housing of the terminal block or on the cross connector, the functionalities of the examiners and the cross-linking are advantageously linked together in a small space.
• the cross-connector housing preferably have on its side facing away from the actual cross connector plug side two juxtaposed insertion openings, one of the insertion for insertion of the actual test plug is used and the other insertion for inserting a plug-in approach for conductive connection with the cross connector plug. If no cross connector plug is provided, the test plug is instead used directly for insertion into a recess of the terminal block housing and for contacting the busbar.
• test plug - if no cross connector is inserted into the recess - plugged directly into the recess of the terminal block housing, in which case the actual test plug dips into the at least one opening of the busbar and contacted them.

• the cross-connector plug housing 14 each form a part of a parent cross connector 15. For the sake of simplicity, this is not shown in FIGS. 3 and 4 for a series of several terminal blocks, but only as a single housing for only a single terminal block (whereby no cross-connection is then realized).
• Each cross connector 15 has in practice a cross connector base housing 18 extending over a plurality (two or more) of juxtaposed cross connector plug housings, through which extends a bus bar 19 (Figure 2d) or other conductor.

It is thus possible to selectively connect only a specific selection of the busbars 6 of the juxtaposed housing 2 to one another in a conductive manner. Alternatively, a separation by means of a tool such as pliers is conceivable.
