In a layout drawing, the information that is typically highlighted for troubleshooting is the locations of devices. Understanding where each device is situated within the layout allows technicians to easily identify and access components that require testing or repair. Accurate device placement helps in quickly isolating issues and determining the relationships between various components within the system.

While operational manuals, line voltage ratings, and wiring colors are important for installation and understanding electrical specifications, they do not provide the immediate spatial information necessary for troubleshooting. Device locations give a practical visual reference, enabling efficient navigation through the field for diagnostic work.
