    L​et’s Understand

    WIRING DIAGRAMS
    A Wiring Diagram is a fundamental conventional graphic illustration of an electrical circuit. It shows
    the simplified shapes, power, lighting, and signal connections between the devices.

    Pictorial Diagram is a type of electrical print that shows the external appearance of each component in a circuit. It is
    much like a photograph of a wiring installation. It shows more detailed physical appearance of a circuit or wiring
    installation.

    Schematic Diagram is a wiring diagram using standard electrical symbols for wiring devices. It is a representation of
    the elements of a system using abstract and graphic symbols rather than realistic pictures.
    Line Diagram is a presentation of electrical connections of wiring devices using a single line and with slashes
    indicating the number of conductors in a line.

    Actual Connection Diagram is a sketch of the actual connections of electrical devices in a circuit or wiring
    installations. Like a schematic diagram it also uses an electrical symbol which is more detailed because it shows the
    wire terminations and connections.
