1. Selecting Tools and
Equipment to Be Used
Based on Job
Requirement

2. The lesson that you are going to tackle in this
module is about selecting tools and
equipment to be used based on job
requirement. Again, another set of activities
are lined up for you to gain mastery of the
competency, selecting the wiring devices
used for floor and ground fault current
interrupter. To continue, read the paragraph
below regarding the diagram.

3. The diagram below is a typical bungalow
residential building electrical wiring plan.
Identify the kitchen and toilet, which are the
most dangerous part of a house where
cooking and laundry appliances are located.
It requires the installation of sophisticated
outlets which protect humans from danger.
Replacement of C.O. or installation of new
GCFI needs electrical tool and equipment to
be used based on the job requirement.

5. An electrical task cannot be done using bare
hands. You need tools and equipment to
systematically accomplish in a short period. This
lesson discusses the common electrical tools and
equipment needed in the installation of electrical
wiring. Tools and equipment are two words that are
often used synonymously, mainly because of the
similarities of their meanings. Because of this
factor, they can be used interchangeably in most
instances. The differences between a tool and an
equipment are stated on the next page.

6.  A tool can be any item that is used to achieve a goal.
Equipment usually denotes a set of tools that are used to achieve
a specific objective.
 A tool can be non-mechanical as well. However, when one
says equipment, there is a certain mechanical aspect to it that
cannot be ignored.
 The usage of tools among human beings runs back millions
of years ago. However, the use of equipment is more of a recent
development.
 Tools are often seen to be used by animals as well.
Equipment is only used by human beings.
 Tools are usually multipurpose. Equipment is designed for a
specific task.

7. Concept Development
The importance of using the right tool for the job
keeps the person safe from accidents. Each tool is
precisely designed for a specific purpose. So,
choosing the correct tool also decreases the
amount of effort required to get a job done right
without causing damage to either the equipment or
surface being worked on. This lesson discusses
the functions/ uses of each tool or equipment used
in electrical wiring installations.

8. Electrical Tools and Equipment
Every trade has a preferred set of tools. For
electricians, there are some tools which are
crucial in the line of work. Others also believe
that these are not required. There are
essential tools that absolutely every
electrician needs to do the job safely,
effectively and for excellent standards.

9. Measuring Tools and Instruments
1. Multimeter
The multimeter measures multiple
electrical properties, including voltage, current, resistance and
DC voltage. Multimeters are available as analog or digital
devices.
Digital Multimeter Analog Multimeter

10. Kinds of Multimeter
Analog multimeter uses a microammeter with a
moving pointer to display readings.
Digital Multimeter is a test tool used to measure
two or more electrical values - principal voltage
(volts), current (amps) and resistance (ohms). It is
a standard diagnostic tool for technicians in the
electrical/ electronic industries, where
measurement readouts can be viewed in liquid
crystal display (LCD).

11. 2. Clamp Ammeter
Clamp Ammeter is also called tong-tester. It is
used to measure current flowing in a conductor. It
is clamped or hanged in a conductor.

12. 3. Phase Sequence Tester

13. 4. Micrometer Caliper
Micrometer Caliper is used to measure the
diameter of wires/ conductors in circular mils. It
can measure small and big sizes of wires and
cables.

14. 5. Wire Gauge
It is used in determining the size of wires/
conductors. The gauge ranges from 0 to 60 awg
(American wire gauge).

15. 6. Ruler/ Foot Rule
It is a measuring tool used to measure length,
width and thickness of short flat object and in
sketching straight lines.

16. 7. Light Tester
It is crucial to know when a wire or device is ‘live’. If you
work on wire while live, there can be dangerous
consequences. Used for a quick safety check to ensure
there is no voltage in an electrical wire or device, voltage
testers are also available in contact and non-contact
designs.

17. 8. Wire Strippers
With a variety of holes to ensure you can work with
different sizes of wire, strippers are used to cut and strip
insulation from electrical wire. The handle should always
be comfortable to hold and easy to grip. Some strippers
will even
include cutting teeth so you can trim the wire ends at the
same time.

18. 9. Circuit Finder
Simply plug the transmitter into the outlet and the
detector will figure out
where the matching directory is. Circuit finders are
also handy to simply trace a circuit.

19. 10. Screwdrivers and Nut Drivers
The following are the screwdrivers and
nut drivers which are specific to
electricians:

20. Philips Screwdriver
This has a cross tip resembling a positive
(+) sign. This is used to drive screws with cross
slot heads.

21. Standard/ Flat Screwdriver
The blade tip is wedge-shaped and resembles
a negative (-) sign. This is used to drive screws
with a single slot head.

22. Stubby Screwdriver
It comes in either standard or Philips screwdriver
with short shank or blade and a shortened handle
used to turn screws in tight space where standard
screwdriver cannot be used.

23. Allen Screwdriver/ Wrench
This could be in the shape of screwdriver or a
wrench. Its function is to drive a screw with
hexagonal slot head.

24. 11. Pliers
Combination Pliers (Lineman’s Pliers)
This is used to grip, hold, cut electrical wires and
cables and even small nails. Usually used by
linemen in doing heavy tasks.

25. Side Cutting Pliers
This type of pliers is used for cutting fine, medium
and big wires and cables.

26. Long Nose Pliers
It is used for cutting and holding fine wires. This
can reach tight spaces or small openings where
other pliers cannot reach and is also used in
making terminal loops of copper wires.

27. 12. Fish Tape
It is used to pull and push stranded or solid wire
through a conduit. Fish tape is always useful. It
can be retracted and deployed as needed as it
comes on a reel which always means it is easy to
grip.

28. 13. Tape Measure
When it comes to tape measures, there is such a
huge variety of styles that it is really a personal
choice. Regardless of whether you like it fatter,
bulkier, slimmer or one that will not buckle over
long distances, a tape measure is needed in a
toolkit.

29. 14. Hammer
It is a pounding tool; a hand tool consisting of a shaft with a metal
head at
right angles used mainly for driving in nails and beating metals.
Claw Hammer Ball peen hammer Mallet (Plastic or rubber hammer)
These are especially important if you are working in a construction
zone. Claw hammers can be used to remove nails and wood pieces.

30. 15. Spirit Level
Make sure your work is level and plumb before
handing it over to the customer.

31. 16. Torch
It can be very dark in places where electrical work
is most needed. It is convenient as well as safe.

32. 17. Electrician’s Knife
Almost all of its kinds are always handy

33. 18. Portable Electric Drill
A small drilling machine with a chuck capacity of
¼” to 3/8”. It is used in making holes on metal
sheets and concrete walls.

34. 19. Hacksaw

cable.

35. 20. EMT Bender
It is a tool used to bend electrical metal tubing.

36. 21. Pipe Cutter
It is used for cutting pipe (IMT, EMT).

37. 22. Reamer
It is used to remove burrs after cutting metallic
tube/ conduit.

38. 23. Die and Dies Stock Set
It keeps the end of the pipe threaded. The sizes of
dies stock range from ½ to 6 inches.

39. 24. Gimlet
It is a small tool for boring holes in wood consisting
of a slim metal rod with a sharp corkscrew end,
fitted in a handle at a right angle.

40. 25. Pencil
It is a writing instrument; a thin cylindrical
instrument used for drawing or writing. It consists
of a rod of graphite or some other erasable
marking material inside a wooden or metal shaft.
