Electrical Design branch of electrical Engineering. Which deal with proposal of designing and calculation of  electrical equipment used in the Building services. Electrical Design contains Planning, Creating and installation of electrical equipment including lighting equipment, power system, Power distribution, Fire alarm and Life safety system. Commercial and industrial buildings contain a number of electrical systems, these plans include specific is a designs and additional documentation to verify that the design conforms to all required building codes. The Design Process: An electrical design goes through several important stages of development. First, the designer must understand the scope of the project. Then, the designer defines and designs each component (such as general office areas, specialized machinery, and power distribution equipment) to recognized industry standards. Finally, these individual components are compiled to form the final presentation for the design.

Power utilization has been increasing over the past few years. From the statistics the Power consumption in India is 672KWH in the year 2007 is increased to 884KWH by the end of 2012. To get through this problem the world is looking forward with new concepts such as Net zero and Renewable Energy resources. Because of this, Electrical industry has become one of the rapidly growing industries making pavement for new jobs. And it is one of the most preferred careers over the period.
