Abstract

In a multi-unit electrical equipment comprising a number of units A, B, Cn, D, each connected to contacts (39, 59) and interconnected by a line (3), a circuit is completed by a unit C2, positioned next to unit C1, which bridges contacts (39, 59) and a contact (19) connected to contact (59) of unit Cn by a line (4). Completion of the circuit in this way avoids the necessity for bridging units to be connected between the contacts (39, 59) at each unit position when checking circuit continuity. <IMAGE>
