Industrial Electrical Blueprint Reading

Course Number: 710

The Industrial Electrical Blueprint Reading textbook focuses on principles that can be applied in many kinds of circumstances to ensure the personal safety of oneself and others. Chapter Two covers the requirements of OSHA and other government agencies. The textbook then provides a thorough explanation of how blueprints are structured and the conventions that are used in making them and reading them. These principles are then applied to electrical drawings. After introducing the concepts of what symbols mean and how they are used in conveying technical information, this course shows how the general principles are applied for specific purposes. The following chapters then focus on how to read and troubleshoot with electrical diagrams.
