Module 4: Electrical Drawings


Nominal duration: 3  weeks (36 hours total time commitment)

This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study.


A drawing should convey precise and identical information to engineers with diverse backgrounds and expertise. This calls for standardized methodologies, conventions and approach in preparing drawings. This module covers all these aspects with respect to engineering drawings in general and electrical drawings in particular. Various types of electrical drawings and their application, the steps in  planning a drawing, selection of drawing size and scale, use of standardized symbols etc. are described in detail with commonly used  examples from industry practice
