4. Learn the words. Top 12 Electrical Tools
Electrical
work will require a few tools to accomplish the job. This is a
partial list of needed tools to take care of most electrical jobs.
These tools are readily available at most building material outlet
stores or electrical wholesalers.
1.
Fish Tape
is used to pull stranded or solid wire through metal or PVC conduit.
Cable lube is available to assist you in pulling the wires through
the pipe.
2. Tape Measure
A tape measure is used to measure heights for switches and
o
utlets.
It is needed to center lighting fixture boxes.
3.
A voltmeter
is used to check voltages and verify that circuits are indeed “live”.
4. A hammer is used to secure boxes equipped with nail-on brackets to studs in a home.
5.
A wrench (a spanner) is
a tool used to provide grip and mechanical advantage in applying
torque to turn objects—usually rotary fasteners, such as nuts and
bolts—or keep them from turning. The most common shapes are called
open-ended spanner and ring spanner.
6. Wire strippers are used to cut the insulation off of the wire. They are equipped with different sized cutting teeth for various sized wires. They also have a cutoff portion in order to cut the wire.

.
Non-contact Voltage Detector is
used for a quick safety check to see if there is voltage or current
flow present. Some of these devices are automatic and some must be
turned on via a switch. Simply place the end of the tracer beside a
wire, breaker or cord to see if it’s energized.
8. Side Cutter Diagonal Pliers are used to cut wire. They are specially designed with a cutting edge that goes down to the tip of the pliers. The advantage being that you can get into tight areas to trim wires. There are some that are equipped with live wire detection capabilities.
9
.
Linesman Pliers
are the do-it-all pliers. They cut, twist wires together, and grip
wires for pulling. They have a squared off end that is great for
twisting wires together, a center cutting blade for cutting wire, and
a grip area between the handles to pull wire.
10. Torpedo Level
A level is used to make sure your work is level and plumb. A great installation starts with straight switch and outlet covers.

1.
A hacksaw is
a fine-tooth hand saw with a blade held under tension in a frame,
used for cutting materials such as metal or plastics. Hand-held
hacksaws consist of a metal arch with a handle, usually a pistol
grip, with pins for attaching a narrow disposable blade.
12. A screwdriver has a handle and a shaft, and a tip that the user inserts into the screw head to turn it. The shaft is usually made of tough steel to resist bending or twisting. The tip may be hardened to resist wear, treated with a dark tip coating for improved visual contrast between tip and screw. Handle are typically wood, metal, or plastic.

For electrical work an electrician must be equipped with the right and proper equipment. Lately a lot of advanced improvements have been made in regard to the various types of tools that are available. While tool options include some that prove very useful and others that prove to be of minor use, some regular tools are required in most electrical events.
Electrician Tools Needed: 1. Hand Tools. To work effectively an electrician needs to possess a number of basic tools. Thanks to the advancement in technology, today's basics are better than older models and provide more comfort and safety than their predecessors. Screwdrivers come in different shapes and sizes. Today electricians work with different types of fasteners and applicators. 2. Measuring Devices. If we take time to observe electricians we would notice that most of them walk around with their tape devices attached to their belt as most electrical work requires measurement. 3. Every electrician has fish tapes and pole. Fish Tapes are used to install new electrical wiring through walls and electrical conduit while Fish poles assist in pulling down wires in ceilings, down walls, or under raised floors. They work with wire strippers. They are used to strip the insulation from electric wires. They are suitably made to provide comfort to the hand when being used. Pliers are used to hold objects firmly when cutting, bending or giving physical compression. There are several different types of pliers which are made for different purposes; the ones mainly used are side-cutting pliers and long-nose or needle-nose pliers. Labeling Machines help to mark materials includes frame ID, rack and panel; cable markers and wire; specialty labels and facilities labels. 4. Power Tools and Testers can be cordless or corded and these are powered by an electrical motor, internal combustion engine, direct burning of fuels and propellants, compressed air, or even natural power sources like wind or moving water. They are classified as stationary or portable; portable being a hand held tool. As we know, the most used powered tools are drills and saw. The type of saws used varies for different type of electric work, and it's the same for power drills. 5. Safety Equipment is important for an electrician for example, safety glasses, gloves, dielectric footwear, and the necessary clothing etc. This is of utmost importance to their safety.
