The document describes different types of wiring diagrams: - Pictorial diagrams show the external appearance of components. - Schematic diagrams use standard electrical symbols. - Line diagrams show connections with single lines and slashes for conductors. - Actual diagrams are more detailed sketches of connections using symbols. Students are asked to interpret a pictorial diagram of a lamp, switch, and outlet, and draw it in the form of a schematic and line diagram. They are then instructed to draw the diagram as an actual diagram for homework.

22.  WIRING DIAGRAM
 Is a fundamental
conventional graphic
illustration of an electrical
circuit. It shows the simplified
shapes, power, lighting, and
signals connections between
the devices.

23.  PICTORIAL DIAGRAM
 Is a type of electrical print
that shows
external
appearance
of each component in a
circuit. Its much like
photograph of a wiring
installation.

24. SCHEMATIC DIAGRAM
 is a wiring diagram using
standard electrical symbols for
wiring devices

25.  LINE DIAGRAM
 is a presentation of electrical
connection of wiring device using
single line and with slashes
indicating the number of
conductors in a line.

26.  ACTUAL DIAGRAM
 is a sketch of the actual connections of
electrical devices in a circuit or wiring
installations.
 Like a schematic diagram it also uses
electrical symbols which is more detailed
because it shows the wire termination and
connection.

27. Application
Direction: Based on the Pictorial Diagram of “one
lamp controlled by a single pole switch and a
convenience outlet.
DRAW IT IN;
