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.

Typical Uses

Electrical engineering diagrams contain a great deal of information. They can identify each piece of an electrical system, as well as its size, its function, and what it is connected to. They are meant to inform people of how a system is set up. They aren't overviews, but contain very specific, detailed information.

Best Practices

• Determine purpose. Decide what system you are going to be making a diagram for.
• Begin with main components. Find out what all of the parts are of your electrical process. Place them on your paper 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 at the top of the page.
• Verify accuracy. Consult with your team members or employees to make sure that your diagram coincides with what they know. Now your diagram can help others better understand your electrical process.
