About this course
Electrical wiring plays a major role in distributing the electrical energy from electric utilities to consumer. Electrical diploma holders may work as Technicians and Supervisors for planning, installing, and testing various electrical wiring Installations such as residential, commercial and Industrial electrification schemes. They should be able to prepare costing and estimates for these schemes with a thorough understanding of the methods/procedure of estimating is desired. Knowledge of IE rules for different types of electrical Installation, their planning considerations equips the students with the capability to plan and prepare different Installation projects. Essential efforts are made in this course to develop above skills in the students.
