ELECTRICAL
INSTALLATION AND
MAINTENANCE
TOOLS AND
EQUIPMENTS
»Ampere - a unit of measure of
electric current
»Circuit - the path of electric
current from the source to the
components and goes
back to the source
»Kilowatt - a unit of power which is
equivalent to 1000w
»Conductor - a wire or a cord which
provides path for current flow
»Resistance - the quality of electric
current measured in ohms that resist
the flow of current
»Hot wire - a wire through which
current flows
» Insulator – material used to cover
electric wires which may be made
from plastic, rubber, or asbestos
» Tools - are implements used to modify
raw materials for human use
» Corrugated plastic conduit (CPC) -
commonly known as flexible non-metallic
conduit or the “moldflex”
» Metallic Conduits - metal raceways that
was classified into four; rigid steel conduit
(RSC), intermediate metallic conduit or
tubing (IMC or IMT), electrical metallic
conduit or tubing (EMC
or EMT) and the flexible
metallic conduit (FMC)
» Non-metallic conduits - plastic conduits
or raceways designed to be a channel of
wire that are classified as; rigid non-
metallic conduit or the PVC,
the flexible nonmetallic or
CPC, and the surface plastic molding
» Connectors and Adapters - accessories
that are used to connect from boxes to
conduits or raceways to the other boxes
in the electrical system
You should be able
to prepare a list of
electrical tools and
materials for a
specific job.

OBJECTIVE:
» 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.
» The blade tip is wedge-shaped and
resembles a negative (-) sign. This is used
to drive screws with a single slot head.
»This has a cross tip resembling a
positive (+) sign. This is used to drive
screws with cross slot heads.
»It comes in either Standard or Philips
screw driver with short shank or blade
and a shorted handle used to turn
screws in tight space where standard
screw driver cannot be used.
»This could be in the shape of a screw
driver or a wrench. Its function is to
drive screw with hexagonal slot head.
»These are tools used in driving or
pounding and pulling out nails. They
are made of hard steel, wood, plastic
or rubber. The following are types of
hammer:
»These made from metal with
insulators in the handle and are used
for cutting, twisting, bending, holding,
and gripping wires and cables.
» This is used for gripping, holding, and
cutting electrical wires and cables and
even small nails. They are usually used
by linemen in doing heavy tasks.
»This type of pliers is used for cutting
fine, medium and big wires and
cables.
»This is used for cutting and holding
fine wires. This can reach tight space
or small opening where other pliers
cannot reach and also used in making
terminal loops of copper wires.
»A tool used for removing insulation of
medium sized wires ranging from
gauge #10 to gauge #16
»This is used by linemen to remove
insulation of wire and cables in low
and high voltage transmission lines.
»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.
»This tool is used to cut metal conduit
and armored cable.
