If you're pursuing a career as an electrician, you will need to learn how to read and use electrical blueprints and schematics. These documents show the layout, design, and specifications of electrical systems and components in different buildings and projects. In the electrician trade school, you will learn the basics of blueprint reading and how to apply it to your residential or commercial electrician work. 

Reading a Blueprint

When reading electrical blueprints and schematics, it's essential to understand the various symbols and abbreviations used to represent different components and elements. 

For example, switches are often depicted as simple squares with a diagonal line. Outlets are typically shown as a circle with two or more prongs. Lights are indicated with a small circle with a cross in the middle, and circuits are usually represented by a series of lines connecting various components.

Wires are generally depicted as lines with arrows indicating the direction of current flow, while transformers are shown as two coils with a dotted line connecting them. Panels are often depicted as rectangles with various symbols and labels indicating their functions and connections. 

Interpreting Different Types of Blueprints

Sections are another type of electrical blueprint that provides a detailed view of a specific area or system within a building. These diagrams often show the construction and installation of electrical components such as panels, switches, and transformers.

Details are yet another type of electrical blueprint providing a close-up view of a specific component or element within an electrical system. These diagrams are typically used to provide detailed information about the following: 

  • A particular component's wiring
  • Connections
  • Installation requirements

Finally, wiring diagrams are a specific type of electrical blueprint showing the connections between different components and elements within an electrical system. These diagrams are essential for troubleshooting and repairing electrical systems, as they clearly and accurately represent the wiring and connections between various components.

Learning About Regulations and Proper Methods 

You must memorize the standards and codes that regulate the design and installation of electrical systems and components. You must learn the methods and tools for measuring, scaling, and drawing electrical blueprints and schematics, such as rulers, compasses, protractors, calculators, and cutting-edge software.

Practicing the Skills You'll Need

You have to master skills and techniques for reading and interpreting electrical blueprints and schematics, such as the following: 

  • Following the flow of electricity
  • Following the flow of tracing circuits, and wires
  • Calculating loads and voltages

You must also be able to identify the scope, purpose, and location of electrical systems and components.

Not only must you be able to interpret the blueprints, but also know the applications and benefits of electrical blueprints and schematics for various installations and projects, such as: 

  • Residential houses
  • Commercial buildings
  • Industrial facilities
  • Solar panels
  • Generators

By learning about blueprints in trade school, you can perform your job as an electrician more efficiently, accurately, and safely.
