  • the present invention further relates to a method for allowing correct mutual positioning of adjacent busbar modules.
  • Busbar modules are known. Busbar modules are usually provided with a box-shaped body and conductive bars arranged inside the box-shaped body. Busbar modules are modular elements, which are connected together in such a way as to determine electrical continuity between the conductive bars of each busbar module. The connection between busbar modules is carried out by means of a junction block or junction box, which constitutes the member responsible for joining adjacent busbar modules, mechanically and electrically. When connecting modular elements, due care must be taken to ensure that the conductive bars of a busbar module are connected to respective conductive bars of the other busbar module having the same phase (or neutral).
  • Correct arrangement of the conductive bars of adjacent busbar modules is the basis for the correct operation of the busbar modules and the system in which they are used. Furthermore, the correct connection of the busbar modules avoids the safety problems of the operators in charge of connecting the busbar modules.
  • making a correct connection of the busbar modules is not usually simple. Often the assembly between busbar modules is carried out in difficult conditions, for example due to the limited space in which the busbar modules are installed or because a portion of the busbar modules or junction block where the assembly is tightened is destined to be facing or placed in the vicinity to a wall, or is destined to be hidden.
