Discussion on design of building electrical supply and distribution lines

The design of power supply and distribution lines in building electrical is a systematic work. In order to improve the design level of power supply and distribution lines, this paper starts the design of electrical supply and distribution lines for buildings, discusses the current supply and distribution lines design in China, and analyzes the electrical construction of buildings. Design problem, based on the design principle of power supply and distribution lines in building electrical, proposes the design method of power supply and distribution lines.
