Electric conductors belonging to several electric circuits dwg
Electric conductors belonging to several electric circuits may be installed in the same protection if the following conditions are met: - all conductors are insulated for the same voltage; - between the sections of the conductors is a difference of no more than three steps; - each circuit is protected against overcurrents; the electrical pipes are installed in protective tubes with diameters chosen according to the section type and the number of pipes. the gaps in the construction elements to protect the electrical conduit are made with a minimum diameter of 15 mm.
