ELECTRICITY

1. Needle-Nose Pliers
 Needle-nose pliers feature long thin blades. They are used for bending bare electrical wire
ends before you attach them to screw terminals located on switches, outlets and circuit
breakers.
Diagonal Cutters
 Diagonal cutters feature jaws that run diagonally to the handle. These particular pliers cut
through wires or even small screws. Those with pivot pins situated close to the jaws give
you greater leverage and this means more cutting pressure to allow you to more easily cut
through thicker grades of wire.

Kneepads
 Kneepads can be your best friend when you are doing electrical installation. Since so much
electrical wiring and outlets are located near floor-level, padding your knees will allow you
to work more comfortably as well as longer.
Continuity Tester
 A continuity tester is one of those special tools used in electrical work. This piece of
equipment tests for whether current is passing from one terminal to another. A continuity
tester becomes very valuable when you are looking for short circuits or improper
grounding.
Voltage Tester
 A voltage tester can determine whether an electrical circuit is live or not. A bulb illuminates
if the terminal is live. If the bulb does not light up, test again by placing the probes between
the ground terminal and each of the live terminals as well as the neutral terminals.
Screwdriver
 Not just any screwdriver should be used all work when dealing with electricity. An
ordinary screwdriver is fine for fastening mounting boxes and attaching switch plates. Use

shaft when doing circuitry work.
Wire Strippers
 Wire strippers are an elemental part of the electrician's toolbox. Look for wire strippers
with jaws that are shaped to cut through the insulation without also damaging the
conductor. A multi-purpose tool adds jobs like cutting screws in one handy piece of
equipment.
Fish Tape
 Fish tape is the unusual name given to a piece of equipment that is made up of a flattened
spring steel wire. Fish tape needs to be stiff enough so that you can work it through small
holes in the wall and between wall studs and floor or ceiling joists. Hook up your electrical
wire to the fish tape and begin feeding it through
