5. Reading and drawing electrical diagrams

Due to the many different manufacturers and the many different products available in the market place only the following diagrams/plans shall be briefly discussed here:

• Connection diagrams
• Device wiring plans
• Circuit diagrams

5.1 Connection diagrams

Connection diagrams normally give an overview of complete installation. In the case of very large installations these diagrams are sometimes split into smaller partial diagrams. In most cases the individual installation components and sections of these diagrams are only shown in schematic form/representation. Furthermore, most connection diagrams are not drawn to scale.
