Abstract: In this paper the electrical design for medical centres is discussed. I designed and made all programs that required calculating and making distribution for the Lighting, Ac System, Sockets, the main Transformer with the Power Factor Correction for the system and Emergency System used in the project. We made a MATLAB program by using Graphical User Interface (GUI) to get the exact value, and the AutoCAD program to distribute the lamps and the socket on each floor. Moreover, I designed the system in emergency case, which is called Automatic Transfer Switch (ATS) that all system required in any cases to make the system keep working for specific time.
