Installing a safe electrical system begins with a well-planned electrical drawing. Standard symbols and lines are used to represent the different types of material, raceways, conduits, and circuit connections. Computer Aided Drafting methods are used to prepare these drawings. Reading and interpreting these drawings accurately is therefore an important skill for technical staff.
This course is designed to help students to understand the electrical lay out drawings of single line, schematic, connection and inter-connection diagrams including logic drawings.
After completing this course, students will have a comprehensive knowledge on preparing neat and accurate electrical engineering drawings for industrial power and control applications.
