A site plan (or position diagram) shows where each electrical point is physically located in your home: sockets, switches, lighting points and circuits, projected onto the floor plan. Together with the single-line diagram it is mandatory for every inspection. With Voltuno you draw both in the same tool, without switching software.

Where the single-line diagram represents the electrical logic, the site plan shows the actual layout. The inspector uses it to compare the installation on site with your documentation.
Both documents are mandatory and complementary. The single-line diagram answers the question "how is everything connected?", the site plan answers "where is everything located?".
Draw your site plan the way you work: quickly sketch your rooms, drop in the components from your single-line diagram and connect them in a few clicks. On A4 and A3, with layers to keep larger projects across multiple floors neatly organised.
