Question: 1 / 400

Which electrical drafting line represents wiring concealed in a floor?

Solid Line

Dashed Line

The dashed line is the correct representation of wiring concealed in a floor in electrical drafting. This convention is used to clearly indicate elements that are not visible in the elevation view of the building or structure. Using dashed lines helps differentiate between visible wiring and those that are hidden behind surfaces, such as floors, walls, or ceilings. This notation is crucial for electrical engineers, contractors, and electricians as it provides an accurate understanding of the layout and installation of electrical systems, ensuring proper planning and execution of electrical work.

By employing dashed lines effectively, drafters can communicate critical information about the placement of wiring without cluttering the drawing with unnecessary detail.
