Most Important Electrical Wiring Diagram Symbols

Hey, in this article we are going to know the most important electrical wiring diagram symbols. Here, we will see the most common symbols used in electrical engineering diagrams. If you are an electrical engineering student or professional then you must know these symbols. Because without knowledge of these symbols, you cannot able to read any electrical wiring diagrams, circuit diagrams, or wiring diagrams.

Electrical Line/Conductor/Wire/Cable Symbol

It is the most important symbol to read any wiring diagrams. All the diagrams have these symbols.

Electrical Line/Conductor/Wire/Cable Symbol

Electric Line Crossing Symbol

When you are going to draw electrical wiring, then you must know this symbol.

Electrical Line Crossing Symbol

Electrical Conductor or Wire Joint Symbol

Electrical Conductor or Wire Joint Symbol

Grounding or Earthing Symbol

The symbol of grounding or earthing is also a very important symbol for electrical wiring diagrams and circuit diagrams. All the electrical installation, machinery, circuits should be connected to the ground.

Grounding or Earthing Symbol

Electric Light Symbol
