Which term describes the arrangement that shows the electrical power connections for devices in a control system?

• A. Power Diagram
• B. Wiring Diagram
• C. Schematic Diagram
• D. Control Diagram

Answer: (A)

This item tests recognizing the diagram type that maps how electrical power is fed to devices in a control system. A power diagram focuses on showing the sources of power and the distribution paths to each device—like relays, contactors, actuators, and the fuses or breakers that protect the circuit. It’s about where power comes from and how it gets to every device that needs energized, not the exact wiring routes or the logical symbols used for the control logic. A wiring diagram, in contrast, shows the physical conductors and how they run between components. A schematic diagram emphasizes the electrical relationships and components in a circuit, often abstracted from physical layout. A control diagram is a less standard term that can refer to the overall control logic layout, not specifically the power distribution.
