Which of the following is generally NOT included in HVAC wiring diagrams?

HVAC wiring diagrams typically focus on the electrical aspects required for the system to operate properly. The reason routing and mounting details are generally not included is that these diagrams prioritize the electrical connections, component specifications, and operational voltage over the mechanical placement of the components.

In wiring diagrams, voltage information is crucial as it indicates the levels needed for proper operation, while wiring colors are essential for identifying the connections and ensuring correct wiring practices are followed. Power source connections are vital components of the diagram because they define how the system will be energized and how energy will flow throughout the setup. However, the physical routing and mounting of components, while important in physical installations, do not appear as critical elements in a wiring schematic since these aspects are often covered in installation guides or separate mechanical drawings.
