The invention relates to a busbar trunking unit (102) for a busbar trunking system (101) having busbars (104) which are elongated in a longitudinal direction (103), are arranged flat next to one another in the busbar housing (105) and are encased by said busbar housing (105), each busbar (104) consisting of two separate partial pieces (104a, 104b) which are designed as rigid profiled elements which are connected to each other in series in the longitudinal direction (103) in an electrically conductive manner, wherein the partial pieces (104a, 104b) are displaceable independently from each other in the busbar housing (105) in the longitudinal direction (103) and can be held fixedly in place perpendicular to the longitudinal direction. According to the invention, the busbar housing (105) consists of two partial sheaths (105a, 105b) which can be displaced telescopically one inside the other for modifying the length of the busbar housing (105). In order to configure the busbar trunking unit in a more cost-effective manner, it is provided that the two partial sheaths (105a, 105b) are made each of an electrically conductive material and are electrically connected to each other such that they form a current path that can be used as a PE conductor. |
