electrical supplies and materials

1. ELECTRICAL SUPPLIES &
MATERIALS

2. Electrical Supplies & Materials
Electrical materials are developed and constructed
for a special purpose such as to:
1. control the flow of current in an electrical circuit;
2. carry electrical current from the source to the load
or current consuming apparatus;
3. hold and secure wires to its fixtures inside and
outside houses and buildings; and
4. protect the houses, buildings, appliances’ and
instruments from any destruction and damage

3. The following are the most commonly
used electrical materials.
1.Convenience Outlet
2.Male Plug
3.Lamp Holders
4.Switch
5.Fuse
6.Circuit Breaker
7.Junction Box
8.Utility Box
9.FlatCord
10.ElectricalWire /Conductor
11.Conduits/Pipes
12.Clamps
13.Connectors

4. Convenience Outlet
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 is
usually fastened on the wall or
connected in an extension cord.
It may be single, duplex, triplex
and could be surface type or
flush type.

5. Male Plug
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.

6. Lamp Holders
A device that hold and
protect the lamp and are also
called Lamp
Sockets/receptacles.
These come in many designs
and sizes.They are classified
as flush, hanging (weather
proof/chain), and surface
types.

7. Switch A device that connects
and disconnects the flow
of electric current in a
circuit.
There are many shapes,
designs, and types ad
they are classified as
hanging, flush and
surface types.

8. Fuse
A circuit protective
device that
automatically blows
and cuts the current
when overload or
short circuit
happens.

9. Circuit Breaker
A protective device
used to automatically
blow and cut the
current when trouble
in the circuit such as
short circuit or
overload occurs.

10. 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 plastic
or metal (PVC)
Polyvinylchlorode

11. Utility Box
A rectangular
shaped plastic or
metallic (PVC)
material in which
flush type
convenience outlet
and switch are
attached.

12. Flat Cord
A duplex stranded wire
used for temporary wiring
installation and commonly
used in extension cord
assembly.
It comes in a roll of 150
meters and sizes of gauge
# 18 and gauge #16 awg (
AmericanWireGauge).

13. Electrical Wire /Conductor
Stranded Wire
A device that hold
andWhich is made of
multiple strands
joined together to
make a single wire.
Solid Wire
It is made of a single
strand of copper or
aluminum wire.
These are used in
wiring installation
inside the buildings.

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

15. Clamps
It is an electrical
materials used to
hold and anchor
electrical conduits
to their proper
position.

16. Connectors
It is used to attached
metallic or non-metallic
conduit to the junction or
utility boxes.

17. Identify the following, write
T if it is Tool and M if it is
Material, write answer on your
answer sheet.

19. One of the basic project
in electrical installation
is to make an extension
cord, as part of this
project your activity is
to list down tools and
materials needed to make
this extension cord.

22. Identify the
following, write the
name of the tool and
material describe to
the following
statement.

23. 1. This has a cross tip resembling a
positive (+) sign. It is used to drive
screws with cross slot heads.
2. This is tools used in driving or
pounding and pulling out nails.
3. A tool used for removing
insulation of medium sized wires
ranging from gauge #10 to gauge
#16.

24. 4. 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.
5. This is a circuit protective device that
automatically blows and cut the current
when an over load or short circuit
happens.
