Which term is interchangeable with Installation Diagram?

• A. Pictorial Diagram
• B. Wiring Diagram
• C. Block Diagram
• D. Schematic Diagram

Answer: (A)

Installation diagrams focus on how equipment is physically arranged and mounted. A pictorial diagram uses images that resemble the real components, showing their shapes, orientation, and how they fit together. Because both are about the actual appearance and placement of parts, they are interchangeable terms. Other diagrams describe electrical connections, functions, or circuit layouts rather than physical layout, so they aren’t interchangeable with installation diagrams.
