ABOUT TOOLS:
1.
Cutting Pliers:-
They
are used to cut the wires, nipping by hand and twisting the wires and also to
hold them. Long nose pliers are used to hold the wires in small space and also
to tighten and loosen small nuts.
2. Nose Pliers:-
Long
nose pliers are used to hold the wires in small space and also to tighten and
loosen small nuts.
3. Screw driver:-
3. Screw driver:-
They
are used to drive and tighten screws into pointed holes in the switches and
electrical machines. They are generally insulated.
4. Hammer:-
Ball
peen and claw hammers are commonly used in electrical work where greater power
is required in striking. It is best suited for riveting purposes in sheet metal
works.
5. Line tester:-
It
is used to check the electric supply in the line or phase wire. It has a small
neon bulb, which indicates the presence of power supply. It can also be used as
a screw driver.
6. Knife:-
It
is generally used for removing the insulation from the wire. The closing type
knife is always preferred.
7.
Pocker:-
It
is a long sharp tool used for making pilot holes in wood before fixing and
tightening wood screws.
8. Center punch:-
When
a hole is to be drilled in a material, the center punch is always used for
making the starting hole.
9. Twist drill:-
It
is used for drilling holes into metals and woods.
10. Soldering rod:-
It
is used for soldering wires to small joints with solder. It consists of pointed
oval Cu bit fixed to an iron rod, which is heated by an electric element only
11. Wire Strippers:-
Wire strippers are used to remove
the insulation from wiring and cable. A better choice is the multi-tool. The
name of this tool gives its advantage away: you can cut cable and strip the
wire without damaging the copper beneath insulation.
12. Wire Cutters:-
You can't expect to do a good job on home wire jobs without a good set of wire cutters. Side cutting pliers are large enough to cut wire and cable. Diagonal cutters are useful for cutting thicker conductors.
