What diagram should include all wire numbers, device code numbers, and area designations?

The correct choice for including all wire numbers, device code numbers, and area designations is the extraction diagram. An extraction diagram is specifically designed to provide a clear representation of the electrical components and their interconnections, making it easier for technicians to understand the system layout and ensure proper installation and maintenance. This diagram serves as a comprehensive reference to track various elements within an electrical system, offering detailed information that is essential for troubleshooting and efficient operation.

In contrast, a connection diagram typically focuses on how devices are connected to one another without necessarily detailing wire numbers and area designations. An installation diagram generally illustrates how components should be physically placed and involves installation procedures rather than detailed wiring information. A wiring schematic provides a simplified representation of electrical circuits but may not include comprehensive details like device codes or specific area designations, as its primary purpose is to show the functional relationships between electrical components.
