Electrical Wiring Diagram - EdrawMax
A wiring diagram is a type of schematic that uses abstract pictorial symbols to show all the interconnections of components in a system. Wiring diagrams are made up of two things: symbols that represent the components in the circuit, and lines that represent the connections between them.
Therefore, from wiring diagrams, you know the relative location of the components and how they are connected. It's a language engineers need to learn when they work on electronics projects.
The Usage of Wiring Diagram
Wiring diagrams are often used in engineering and educational fields to illustrate how electronic devices are built. Wiring diagrams are easy to draw and understand. Professionals can study wiring diagrams to determine if electronic devices have been set up properly and safely. In addition, they allow anyone to understand how devices are made up, and can facilitate repairs as well.
Wiring Diagram VS. Schematics
A schematic, or schematic diagram, represents the elements of a system with abstract and graphic symbols instead of realistic pictures. A schematic diagram focuses more on comprehending and spreading information rather than doing physical operations. For this reason, a schematic usually omits details that are not relevant to the information that it intends to convey and may add simplified elements to help readers understand the features and relationships.
A wiring diagram (also named electrical diagram, elementary diagram, and electronic schematic) is a graphical representation of an electrical circuit. Wiring diagrams are widely used for circuit design, construction, and maintenance of electrical and electronic equipment. Wiring diagrams can be divided into two categories - pictorial wiring diagram and schematic wiring diagram.
Start a wiring diagram design using industry-standard symbols that everybody understands. Here are the symbols that are often used when creating wiring diagrams. The symbols below all come from Edraw. It shows partially from the built-in electrical symbol library.
Wiring diagrams use simplified symbols to represent switches, lights, outlets, etc. Here is the wiring symbol legend, which is a detailed documentation of common symbols that are used in wiring diagrams, home wiring plans, and electrical wiring blueprints.
How to Read A Wiring Diagram
To read a wiring diagram, you should know different symbols used, such as the main symbols, lines, and the various connections.
Step 1: Recognize Wiring Diagram Symbols
To read a wiring diagram, first, you have to know what fundamental elements are included in a wiring diagram, and which pictorial symbols are used to represent them. The common elements in a wiring diagram are ground, power supply, wire and connection, output devices, switches, resistors, logic gate, lights, etc. A list of electrical symbols and descriptions can be found on the "electrical symbol" page.
Step 2: Line Junction
A line represents a wire. Wires are used to connect the components. All points along the wire are identical and connected. Wires on some places need to cross each other, but that does not necessarily mean that they connect. A black dot is used to indicate the injunction of two lines. The main lines are represented by L1, L2, and so on. Usually, different colors are used to distinguish the wires. There should be a legend on the wiring diagram to tell you what each color means.
Step 2: Types of Connections
Usually, circuits with more than two components have two basic types of connections: series and parallel. A series circuit is a circuit in which components are connected along a single path, so the current flows through one component to get to the next one. In a series circuit, voltages add up for all components connected in the circuit, and currents are the same through all components. In a parallel circuit, each device is directly connected to the power source, so each device receives the same voltage. The current in a parallel circuit flows along each parallel branch and re-combines when the branches meet again.

- A good wiring diagram needs to be technically correct and clear to read. Take care of every detail. For example, the diagram should show the correct direction of the positive and negative terminals of each component;
- Use the right symbols. Learn the meanings of the basic circuit symbols and choose the correct ones to use. Some of the symbols have a close look. You need to be able to tell the differences before applying them;
- Draw connecting wires as straight lines. Use a dot to indicate line junction, or use line jumps to indicate cross lines that are not connected;
- Label components such as resistors and capacitors with their values. Make sure the text placement looks clean;
- In general, it is good to put the positive (+) supply at the top, and the negative (-) supply at the bottom, and the logical flow from left to right;
- Try to arrange the placement, reducing wire crossings.
