BRIEF INTRODUCTION
Electrical task can be accomplished systematically to save time, effort, and resources.
Most of the work cannot be done using bare hands. To do the task, electrical tools or materials
are needed to perform the job. This lesson will discuss the function/use of each tool or
materials used in electrical wiring installations.
The following are common electrical tools needed in the installation of electrical
wiring/devices
1. Screwdrivers -these tools are made of steel hardened and tempered at the tip used to
loosen or tighten screws with slotted heads. They come in various sizes and shapes.
1.1 Flat Screwdriver - the blade tip is wedge
shaped and resembles a negative (-) sign.
This is used to drive screws with a single slot
head.
1.2 Phillips Screwdriver- this has a cross tip
resembling a positive (+) sign. This is used to
drive screws with cross slot heads.

1.3 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.

1.4 Stubby Screwdriver - it comes in either
Standard or Phillips screwdriver with short
shank or blade and a shorted handle, used to
turn screws in tight space where standard
screwdriver cannot be used.

2. Pliers - are made of metal with insulators in the handle. They are used for cutting,
twisting, bending, and holding wires and cables.
2.1 Combination Pliers – usually called as
linemen’s pliers, used to hold, bend, and
cut electrical wires and cables.
2.2 Side Cutting Pliers – also called as
diagonal pliers. This type of pliers is used
for cutting small to medium size of wires

7. Wire Stripper - this is a tool used for removing
insulation of medium-sized wires. It has two types:
1.Manual - has round holes that correspond to wire
size. Removing of insulation is done while squeezing and
pulling out wire. This can also be used to cut mediumsized copper wires.
2. Automatic - operated by squeezing where one end
will hold the wire and the other will remove the insulation,

materials/devices:
1. Convenience Outlet (CO)- 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. This can be surface type or flush type. Flush type C.O.

circuit. There are many
shapes, designs and types
and are classified as hanging, Flush type

3. Receptacle - is a device that
holds the lamp in place to safely
connect the wires to the circuit.
This is usually made of porcelain or
plastic and classified as flush,
hanging (weather-proof/chain) and
surface types.
Flush type
4. Junction Box - an
octagonal
shaped
electrical material where
the connections or joints
of wire are being done. It
is also where the flush
type
