TLE_IAEI9ET-Ia-e-1
1.1 Request tools, equipment and materials
II.
III.
Objectives
a. Request tools, equipment, and materials
b. Identify electric and hydraulic tools for the task
Background Information
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 equipment are needed to perform the job. This lesson will discuss
the function/use of each tool or equipment used in electrical wiring installations.
INFORMATION SHEET 1.1
ELECTRICAL TOOLS AND MATERIALS
Pliers. They could be with insulated or uninsulated handles. The handle insulation is not
considered sufficient protection alone. Other safety precaution must be observed. The
common types of pliers are:
Slip joint
Diagonal cutting
Long nose
Side cutting
Snap ring
Retainer ring

Screw drivers are used to drive and pull-out screws. They come in various sizes
and shapes and with either sharp or square tips. The width of the screw driver
should match the width of the screw slot. Common types of
screw drivers are:
Standard type
Phillips
Offset
Wire puller (fish wire) is used to pull wires into the conduit or raceway.
EMT bender is a tool used to bend electrical metal tubing.
Drilling Equipment is needed to make holes in building structure for passage of
wires and conduit in both new and old installation, indoor or outdoor wiring.
Common types of drilling tools and equipment are:
Electric drill
Auger brace
2
Hand drill
Gimlet
Drill bits
Masonry bit
Soldering tools are used in making splices and taps connections of wires.
Soldering gun
Blow torch
Hammers are used to drive and pull-out nails. They are made of either hard
steel or plastic. A claw hammer with fiberglass insulated handle is specially
designed for electricians. Common examples of hammer are:
3
Measuring tools and instrument. The electrician uses the following measuring
tools and devices to measure value of voltage, current and resistance, wire length,
opening sizes of wire, conduit and other items.
Sawing and cutting tool. Two of the commonly used types of saws are:
