What are the three rules for reading schematics and wiring diagrams?

The three primary rules for reading schematics and wiring diagrams are:

1. Understand Symbols: Familiarize yourself with common electrical symbols used in diagrams, as they represent various components like resistors, capacitors, and switches.
2. Follow the Flow: Recognize the flow of electricity, typically from the power source through the components, which helps in tracing paths and understanding circuit functionality.
3. Refer to the Legend: Always consult the legend or key if provided, as it explains the specific symbols and conventions used in the diagram, ensuring accurate interpretation.
