Lewellyn Technology Electrical Ladder Drawings I

The seminar starts by explaining various types of electrical diagrams that industrial maintenance personnel use, their applications, and the standards associated with them. This is followed by a detailed discussion on the basic symbols used in electrical diagrams. Included in this discussion are push buttons, selector switches, limit switches, relays, timing relays, motor starters, transformers and more. Understanding these symbols and what they represent is the foundation for reading electrical diagrams.

You will learn how these symbols are used to make the common motor control center and circuits used in industrial electricity today. Actual electrical diagrams of machinery will be used to reinforce print standards and will be used in realistic electrical troubleshooting examples led by the instructor.

In this one-day seminar you will learn the basics of reading and understanding electrical drawings. This seminar is great for both the beginner and someone with years of experience with no formal training. It will cover topics that personnel involved in electrical maintenance must know to effectively use electrical diagrams. This is not a seminar on electrical theory; the discussion will be practical and led by an instructor with many years of industrial maintenance training experience.
