Upon completion of this course the participant will be able to understand:

• The purpose of symbols in logic drawings
• Identify electrical components
• Electrical Drawing Abbreviations, Symbols, and Terminology
• Identify Different Types of Electrical Drawings
• How to interpret electrical, earthling and cabling layouts
• How to create a block map of the installed equipment
• Transfer the information to the one-line diagram
• Understanding to ladder diagrams, Logic symbols, their Interpretation and use
• Verify electrical prints and maintain regulatory compliant electrical diagrams
• Revising and Updating the drawings

Electrical drawings are a formal and precise way of communicating information about the layout, the dimensions, features and precision of Electrical installations. Drawing is the universal language of engineering. To understand how to “read and interpret” a drawing it is necessary to be familiar with the standard conventions, rules, and symbols used on the various types of electrical drawings.

The purpose of this course is to prepare electrical personnel with the ability to read and understand the electrical diagrams, various standards and practices used for reading and Interpreting electrical drawings and schematics. Participants will be introduced to electrical symbols, one-line and three-line electrical schematics and their content, including basic layout and legends. The course will help the attendees understand the symbols and the language used in electrical drawings in line with the international standards and practices, giving a detailed insight into the various types of electrical drawings used in the industry, their purpose and applications.

The course gives emphasis on practical exercises in drawing reading, diagram verification and understanding the accurate meaning.
