These electrical symbol is different depend on country standard code and application.It not the big matter because the important thing is we can done our electrical installation works in proper manner and completed it with successful.
Here i attached one of electrical wiring diagram for example.These is called by layout drawing.From these we easier can do our jobs with actual location for all equipment installation and electrical wiring purpose.
I will explain detail about several types of drawing for electrical installation in my next post.We can discuss about as-fitted drawing,detail drawing,location drawing,distribution cable wiring,block diagram and more.
