3. Terminologies
Supply – to provide with
Materials – consumable
Utility – designed for
general use.

4. The following are electrical devices and
materials used in the assembly of basic
electrical gadgets such as extension cord,
lamp shade, etc. These are developed and
constructed for a special purpose such as
to:
 Control the flow of current in an
electrical circuit.
 Carry electrical current from the source
to the load or current consuming
apparatus.

5.  Control the flow of current in an
electrical circuit.
 Carry electrical current from the source
to the load or current consuming
apparatus.
 Hold and secure wires to its fixtures
inside and outside houses and
buildings.
 Protect the houses, buildings,
appliances and instruments from any
destruction and damage.

6. CONVENIENCE OUTLET
Convenience Outlet is a device that
acts as a convenient source of
electrical energy for current consuming
appliances. It is where the male plug
of an appliance is inserted and usually
fastened on the wall or connected in
an extension cord. It maybe single,
duplex, triplex or multiplex and
could be surface type or flush type.

7. CONVENIENCE OUTLET

8. MALE / AC PLUG
Male Plug - is a device inserted to
a convenience outlet to conduct
electric current. A flat cord is
attached to it on one end and the
other end is connected to a
current consuming instrument or
appliance.

10. LAMP HOLDER
Lamp Holder – This is an
electrical device that is used to
hold and protect incandescent or
compact fluorescent lamp. It is
also called as “Lamp
Socket/Receptacle”.

11. LAMP HOLDER

12. SWITCH
Switch - is a device that connects
and disconnects the flow of
electric current in a circuit.
Switches are classified as
hanging, flush and surface types.

13. SWITCH

14. FUSE
Fuse - a circuit protective
device that automatically blows
and cuts the current when
overload or short circuit
happens.

20. CIRCUIT BREAKER
Circuit Breaker - a protective
device used to cut or interrupt
automatically the current when
trouble in the circuit such as short
circuit or overload occurs.

21. CIRCUIT BREAKER

22. UTILITY BOX
Utility Box - a rectangular
shaped metallic or plastic (PVC)
material in which flush type
convenience outlet and switch
are attached.

23. UTILITY BOX

24. JUNCTION BOX
Junction Box – an octagonal
shaped electrical material where
the connections or joints of wires
are being done. It is also where
the flush type lamp holder is
attached. This could be made of
metal or plastic (PVC)
Polyvinylchloride.

25. JUNCTION BOX

26. FLAT CORD
Flat Cord - a duplex stranded
wire used for temporary wiring
installation and commonly used
in extension cord assembly.

27. FLAT CORD

28. ELECTRICAL WIRE OR
CONDUCTOR
Electrical Wire/Conductor-
electrical material that could be:
Stranded wire which is made of
multiple strands joined together to
make a single wire.
Solid wire is made of a single strand
of copper or aluminum wire. These
are used in wiring installation inside
and outside the buildings.

29. ELECTRICAL WIRE OR
CONDUCTOR

30. ELECTRICAL CONDUITS
/ PIPES
Electrical Conduits/Pipes -
electrical materials used as the
passage of wires for protection and
insulation. These could be rigid
metallic, flexible metallic conduit
(FMC), rigid non-metallic (PVC),
and flexible non-metallic or
corrugated plastic conduit (CPC).

31. ELECTRICAL CONDUITS
/ PIPES
Rigid Non-metallic conduit (PVC)
and Metallic conduit

32. ELECTRICAL CONDUITS
/ PIPES
Flexible Non-metallic conduit or
corrugated plastic conduit (CPC)

33. ELECTRICAL CONDUITS
/ PIPES

34. ELECTRICAL TAPE
Electrical Tape – used to
protect and cover live or
open wires.

35. ELECTRICAL TAPE

36. ACTIVITY
By group, name the 5 actual electrical
supplies and materials that your
groupmates brought to school. Write
your answers in a 1/4 sheet of paper.
Afterwards, present your answers to
the class using the realias. Note: every
correct answer is equivalent to 4
points. 20 for the highest score and 0
for the lowest score.

37. Quiz
Direction: Identify the given electrical supply. Write
the answer at the back of your big notebook.

40. TYPES OF
ELECTRICAL
CONDUITS

41. PVC CONDUIT PIPE
PVC Conduit Pipe – are popular
type of electrical conduit used for
above ground and underground
applications. These conduits are
made of high quality PVC and are
flexible in nature. The pipes have
high electrical strength and impact
resistance.

42. PVC CONDUIT PIPE

43. RIGID STEEL CONDUIT
Rigid Steel Conduit – This
heavy-duty pipe has threaded
ends.

44. ELECTRICAL METALLIC
TUBING (EMT)
Electrical Metallic Tubing (EMT)
– These conduits are relatively
easy to bend, cut, and form. This
light gauge pipe is also known as
thin wall conduit.

45. ELECTRICAL METALLIC
TUBING (EMT)

46. NONMETALLIC CONDUITS OR
PVC CONDUITS
Nonmetallic Conduits or PVC
Conduits – These are circular in
shape and generally corrugated.
These conduits are used in
underground installations. These are
popular because these provide high
strength, have a low absorption rate,
watertight joints, and have low
installation costs.

47. NONMETALLIC CONDUITS OR
PVC CONDUITS

48. GALVANIZED RIGID
CONDUITS (GRC)
Galvanized Rigid Conduits
(GRC) – These metallic conduits
are coated with zinc for
increasing resistance to
corrosion and abrasion.

49. GALVANIZED RIGID
CONDUITS (GRC)

50. INTERMEDIATE METAL
CONDUITS (IMC)
Intermediate Metal Conduits
(IMC) - These have circular
raceways that are rigid and have
thinner walls as compared to
rigid metal conduits.

51. INTERMEDIATE METAL
CONDUITS (IMC)

52. FLEXIBLE METALIC
CONDUIT
Flexible Metallic Conduit –
This is a variety of piping used to
hold electrical wires and similar
cabling.
