Electrical Blueprint Reading

Course #: 006036
Duration: 10 hours
Course Prerequisites: AC Principles (Block A22); Basic Industrial Math (Block X21);
What Students Learn: In this study unit, you will learn to read several different types of electrical blueprints. Reading and understanding the information that appears on a blueprint will be emphasized, not the design details of a particular project. Engineers and designers use blueprints to present design information in a variety of ways. The general principles for preparing blueprints will also be covered. The skills you learn can be applied to reading blueprints for residential, commercial, manufacturing, and electric utility projects.

When students complete this study unit, you will be able to:

  • Explain how blueprints are prepared.
  • Discuss how and why blueprints are copies of original drawings.
  • Talk about the relationship of electrical blueprints to the architectural drawings and drawings of other trades.
  • Read and understand the information presented on blueprints.
  • Identify the different methods of presenting information.
  • Interpret the common symbols used on electrical blueprints.
  • List the common abbreviations used on electrical blueprints.
  • Trace a wiring diagram and understand it.

    Special Notes: This updated course replaces, Electrical Blueprint Reading, course 6635.
