III.Instructional Procedures
Teacher’s Activity
A.Pre-activity
1.Review
What are the different types
of wiring devices?
What are three types of
GFCI?
Student’s Activity
Teacher’s Note
The different types of wiring devices
are Switches, Relays, Conductors,
Contactors and Receptacles.
Very Good!
The three types of GFCI are
Receptacle GFCI, Temporary/Portable
GFCI, and Circuit breaker GFCI.
Very Good!

3.Presentation
Our topic for today is about
Types of wiring diagram.
The teacher give brief
information regarding Schematic,
Actual, Line and Pictorial diagram.
B.Lesson Proper
A.1. Activity
Divide the class into 4
groups. Choose a leader, secretary
and a reporter. Each member should
cooperate and work silently. Each
group will be given 5 minutes to do
the activity and 3 minutes per group
for the reporting.
A.2. Analysis
SCHEMATIC DIAGRAM
Very Good!
ACTUAL WIRING DIAGRAM
Correct!
LINE DIAGRAM
Very Good!
PICTORIAL DIAGRAM
Very Good!
Actual wiring diagram because you
need to show the proper actual
connections of wires.
Excellent!
Group 1 based on the
activity, what diagram is assigned to
your group?
Teacher give enrichment
after each reporter
How about Group 2, what
diagram is assigned to your group?
How about Group 3?
Group 4, what diagram is
assigned to your group?
Okay class, based on the
activity what do you think difficult for
you to draw? Why?
What diagram is easy to draw?
Why?
Line diagram because it has only
single line that represent its
connection.
Very Good!
A.3. Abstraction
The different types of wiring
What are the different types of diagram are Line diagram, Actual
wiring diagram?
wiring diagram, Line diagram, and
Pictorial diagram.
How does schematic diagram
differ from actual, line and pictorial
diagram?
How does actual wiring
diagram differ from schematic, line,
and pictorial diagram?
It has schematic symbols that
represents each components in a
circuit.
It shows the actual connections
from one component to another
component of a circuit.
Very Good!
Correct!
Very Good!
How does line diagram differ
from schematic, actual, and pictorial
diagram?
How does pictorial diagram
differ from schematic, actual, and
line diagram?
Why is wiring diagram
important for any electrical
installation as well as in doing
electrical repair or troubleshooting?
It has single line that represents
its connections.
Very Good!
It shows the external appearance
of the circuit.
Very Good!
It is important because wiring
diagrams is our basis or guide in
installing electrical wiring system.
Excellent!
A.4. Application
Correct!
I need four (4) representatives
to draw on the board the different
wiring diagrams of one lamp
controlled by single pole switch using
a circuit breaker.
Very Good!
Correct!
Very Good!
