Why is practice important for reading schematic diagrams?
What will be an ideal response?
The old saying "Practice makes perfect" certainly applies to reading schematic diagrams. Although there are notations that are common to many industrial control schematics, nothing is standard. Many manufacturers use their own numbering and notation system, specific to their company. Some use the NEMA symbols that are discussed in this text and others do not. With practice and an understanding of basic control logic and schematics, most electricians can determine what these different symbols mean and the way they are used in a circuit.
