An electrical drawing doesn’t show the wiring, cable or conduit layout. It shows where each electrical point is situated within the building, and gives a brief description and a specification if necessary. An example of a simple electrical legend is shown in Figure 13.7. When compiling the electrical drawings, the architect and home owner will look into the functionality of the home and the home owner’s lifestyle and needs. See below for some design tips.

Electrical Drawing

Without proper drawings and specifications, it becomes extremely difficult to undertake an electrical installation, if not impossible. In commercial and industrial projects where the electrical installation can be complex, drawings are in most cases provided by the architect. Unfortunately, in residential buildings, electrical drawings are sadly lacking. Home owners are urged to firstly employ an architectural professional to provide a full service and then make sure that an electrical drawing is compiled.
