4. What are the things to
consider in
planning / preparing
electrical wiring or
electronic circuit correctly?
5. Electrical & Electronic symbols and
images are used by engineers in circuit
diagrams and schematics to show how a
circuits components are connected
together.
6. Different terms and symbols
• Load
are electrical devices like lighting fixture and appliances
that consumes electrical energy
• Source
electrical energy coming from either alternating current or
direct current that provides electrical power to the circuit.
• L1s
= Line 1 of the source
• L2s
= Line 2 of the source
7. • T1L
= Line 1 of the load
• T2L
= Line 1 of the load
• T1
= Terminal 1 of the switch
• T2
= Terminal 1 of the switch
• Sw
= single pole switch
• S3w
= 3 way switch
8. • = jumper
• = circuit breaker
• = junction box
• CO
= convenience outlet
`
• = single pole switch
• = 3 way switch

9. Steps in Wiring Installation
1. Line 1 of the source connected to line
1 of the load.
2. Line 2 of load connected to terminal 1
of the switch
3. Terminal 2 of switch connected to line
2 of source.
14. Travelers - provides two alternate
pathways for hot current to flow between
the switches—this is what allows the
switches to turn the lights on and off in a
flexible manner
17. 1) Single pole switch wiring connection 2) 3 way switch wiring connection
18. As a student, is wiring installation
can give benefit to you? In what
possible way?
19. • What are the terms use in wiring
installation? Draw its symbol.
• Recite the basic steps in building wiring
installation?
• In what specific lesson of other areas
we can integrate this lesson?
20. Assuming that you are an electrical engineer,
your client ask you to draw an actual wiring
diagram of a house with materials of 2
junction box, 1 circuit breaker, and 1
lightbulb controlled by single pole switch
(Sw).
With this material, draw your own actual
wiring diagram.
Do it yourself!!
