ABSTRACT:
A modular element for an electrical power distribution ducting has an elongated box section structure. Inside the box section structure conducting electrical power distribution bars are arranged. Lateral access can be gained to the bars through distribution openings in the box section structure. At least some of the openings are protected by a closing-off protective device in the absence of a tapping. The box section structure is composed of two beam members each having two longitudinal grooves into which the respective longitudinal edges of two pre-shaped strips having a U-shaped cross section engage elastically. The edges are fixedly retained inside the longitudinal grooves of the beam members. One of the beam members optionally carries bus bars for low current power distribution.
