description: The subject of the graduate qualification work is Â«Designing of the power supply system of a residential complexÂ». The scheme of external power supply for a projected multi-apartment residential complex of 12 buildings with public buildings for entertainment and leisure purposes, public utilities and lighting of access roads, located in the Leningrad Region, is presented in this work. Methods for choosing circuit breakers and fuses are considered, also their differences and measures, performed to achieve compliance with the requirements of the EIR are described. The calculation of loads of consumers in normal, emergency and Â«accident + fireÂ» modes, preliminary selection of cables and switching devices are carried out. The maximum and minimum short-circuit currents are calculated at a distance of 1 meter from the protection device and at the end of the cable line. The choice of the main equipment and current-carrying parts were made, also a study of the influence of the choice of 0.4 kV switching devices on the power supply scheme, its characteristics, the possibility and cost of the project implementation was made. A cable list was compiled and a plan of external power supply system was displayed on a simplified general plan.
