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.
Side Cutting Pliers - This type of pliers is
used for cutting fine, medium, and big
and cable.
Long Nose Pliers - This is used for cutting
and holding fine wires. This can reach
spaces or small openings where other
pliers cannot reach and is also used in
making terminal loops of copper wires.
Wire Stripper - This is a tool used for
stripping or removing the insulation of
connecting wires ranging from gauge #10
to gauge #16.
D. Cutting Tools
Electrician’s Knife - This is used by linemen
to remove insulation of wire and cables in
low and high voltage transmission lines.
Hacksaw - This tool is used for cutting
pipes/conduit and cables. It is also used for
cutting big conductors.
