Engineering Diagram

Electrical Engineering Diagrams are meant to communicate how different parts of an electrical system are interrelated. They use a universal system of symbols that indicate different electrical parts and make it easy for anyone who knows these symbols to also understand the diagram.

Engineering Diagram
Typical Uses

Electrical Engineering Diagrams contain a great deal of information. They contain very specific, detailed information and can identify each piece of an electrical system, as well as its size, its function, and what it is connected to. If the system already exists, the diagram acts as a map. If it does not exist, the diagram is used as a plan for the system's construction.

Best Practices
  • Determine purpose. Decide what system you are going to be making a diagram for.
  • Begin with main components. Analyze the electrical process to discover its layout. Place them on the page in a similar order as they are found in the actual system.
  • Make connections. Use lines with arrows to connect various parts of the electrical system. These lines can also suggest how many wires are connected to a specific part.
  • Label. Write what the various pieces are and also write their size and any other pertinent information. Also write the name of the system or its function at the top of the page.
  • Verify accuracy. Consult with team members or employees to confirm that the diagram coincides with system requirements.
