Electrical Wiring Diagram Symbols Chart
An electrical wiring diagram is a simplified representation of an electrical system. It uses symbols to represent the different components of the system, such as wires, switches, outlets, and fixtures. Wiring diagrams are used to help electricians install, maintain, and troubleshoot electrical systems.
There are many different types of electrical wiring diagram symbols. Some of the most common symbols include:
- Wires: Wires are represented by lines. The thickness of the line indicates the wire’s gauge. The color of the line indicates the wire’s insulation type.
- Switches: Switches are represented by circles or rectangles. The type of switch is indicated by the symbol’s shape. For example, a single-pole switch is represented by a circle, while a double-pole switch is represented by a rectangle.
- Outlets: Outlets are represented by squares or rectangles. The type of outlet is indicated by the symbol’s shape. For example, a standard outlet is represented by a square, while a GFCI outlet is represented by a rectangle with a ground fault indicator.
- Fixtures: Fixtures are represented by various symbols, depending on the type of fixture. For example, a light fixture is represented by a circle with a light bulb inside, while a fan is represented by a circle with a fan blade inside.
Creating an electrical wiring diagram is a relatively simple process. The first step is to draw a schematic diagram of the electrical system. This diagram should show the location of all of the components in the system, as well as the wires that connect them. Once the schematic diagram is complete, you can begin to add the symbols for the different components.
Electrical wiring diagrams are an essential tool for electricians. They help electricians to install, maintain, and troubleshoot electrical systems. By understanding the symbols used in electrical wiring diagrams, you can better understand how electrical systems work.
