The distribution panel contains the elements for the protection and control of the electricity supply of the house. The electrical system is organized from this panel and the power of the installation is distributed. In the single-line diagram the electrical panel is usually represented by a rectangle drawn with a dotted line.

Definition: Single line diagram is the representation of a power system using the simple symbol for each component. The single line diagram of a power system is the network which shows the main connections and arrangement of the system components along with their data (such as output rating, voltage, resistance and reactance, etc.).

We usually depict the electrical distribution system by a graphic representation called a single line diagram (SLD). A single line can show all or part of a system. It is very versatile and comprehensive because it can depict a very complicated three-phase system.
