The bus bar (1) has a protective conductor (9) located at floor wall of bus bar and exposed in retaining channel (2). The conductors (10,11) are insulated from side pairs of respective conductors (5-8) and arranged between each conductor pair held in support rail (3). The conductors are transversely opposite to one another. Both conductors on side walls are exposed in retaining channel. The conductors are used as control conductors for electrical or electronic controller, or additional supply conductor for other electrical load. |
