Which electrical drawing would likely not be found in residential sets?

The correct answer is related to the specific context and requirements of residential sets versus commercial or industrial projects. Cable Tray Layouts are typically associated with larger-scale installations, such as commercial buildings or industrial facilities, where extensive electrical distribution systems and organized pathways for cable management are necessary. In residential settings, electrical systems are generally simpler and do not utilize cable trays, as the wiring is typically routed directly through walls and ceilings without the need for such infrastructure.

In contrast, floor plan drawings, electrical riser drawings, and site plan drawings are all commonly utilized in residential projects. Floor plans outline the layout of the rooms and spaces within a home, electrical riser drawings illustrate the vertical connections of electrical systems, and site plans show the relationship of the building to the lot and surrounding features. These elements are essential for understanding and implementing residential electrical designs, making them regularly found in residential documentation.
