What is a Wiring Diagram and How to Read it? Do you have struggles reading and using an electrical wiring diagram? If yes, don't worry! By end of this video, you'll have a good understanding of how to read, understand, and use any wiring diagram for your benefit.
An electrical wiring diagram could be a single-page schematic of how a ceiling fan should be connected to the power source and its remote switches so that we can turn it on and off.
A wiring diagram may include the wiring of a vehicle. For example, how the horns are powered and connected to the controller on your steering wheel.
Or an electrical wiring diagram can be a 200-page document including all the electrical wirings of an electrical control panel in a huge factory or plant.
Wiring diagrams may follow different standards depending on the country they are going to be used. They may have different layouts depending on the company and the designer who is designing that.
They also may be drawn by different ECAD software such as EPLAN or AutoCAD electrical. So, when you see a wiring diagram for the first time, you may need some time to analyze it and become familiar with its layout and symbols.
During this video, you'll learn about different things like wire tags and some electrical components and their symbols such as terminal blocks, terminal strips, circuit breakers, power supplies, ground chassis, safety relays, and so on.
