Abstract
Today's technology is based on civil electrical power, electronics, electrical equipment and electrical technology as a means to create, maintain and improve the people who live or work in the living environment of the electrical, optical, sound, cold and warm environment, a comprehensive interdisciplinary technical and scientific. It is the strong and weak electricity and an organic combination of concrete construction. In this paper, the main service center on a floor 2,3 # distribution for the system engineering principles, based on the design method and design choices and conclusions. Including load calculation, lighting design and the design of grounding and lightning protection design of the fire. The design drawing AUTOCAD design software, to complete a total of 18 drawings total, of which some 10 strong power, weak part 6.
Key Words: load calculation, lighting, , wire, the power supply, Emergency lighting
