1. Allen Wrench

2. Non-Contact Voltage Tester / Tick Tester

3.  Lineman Plier

4. Side Cutter or Dykes

5. Fish Tape

6. Volt meter or Multi meter

7. Electric Drill

8. Screw Gauge

9. Vernier Caliper

10. Coaxial Crimper

(8) Allen Wrench

Allen wrenches are used to tighten hex head screws, which are sometimes found on ceiling fans, light fixtures and other devices.

       

(9) Non-Contact Voltage Tester / Tick Tester

Voltage tester is used to quickly and safely check the voltage. To ensure that there is no voltage in the electrical wire or device before starting work on it. Non-contact voltage testers, which run on batteries, are the simplest and safest type of tester because they can detect electricity only by staying close to an outlet slot and wire.

               

(10) Lineman Plier

A pair of lineman pliers is an electrician's all-purpose tool. Its ends have handles for twisting the wires together, the main cutting blade for cutting the wire and for pulling and separating wire.

     

(11) Side Cutter or Dykes

Sided cutters or dykes are used to cut wires. They are specially designed with a cutting edge that extends to the tip of the jaws, allowing you to cut wires even in tight spaces. Some types of dykes also have a built-in voltage detector to detect the presence of current inside the wires.

     

(12) Fish Tape

Fish tape is used to pull trapped or solid wire conductors through a metal or PVC duct. The cable lobe helps you pull the wires through the duct. Fish tape can also be helpful when you are pulling cable from the depths of the wall.
It is a device used to improve wiring or to make new wiring, such as adding or extending new circuits.

       

(13) Volt meter or Multi meter

The voltmeter is used to read the voltage level and verify that the circuit is on or off. Unlike a circuit tester, this tool also tells you how much voltage is in the circuit. The most sophisticated device is known as a multi meter, and it can read not only voltage levels but also AC current and resistance, as well as DC current and resistance. However, it takes practice to learn how to use them properly.

     

(14) Electric Drill

An electric drill is a tool that is mainly used to drill round holes or self-screws. It is fitted with a bit, either a drill or a driver. Some electrical drills also have a hammering function.

     

(15) Screw Gauge

A screw gauge is a device used to measure the diameter of a thin wire or the width of a metal sheet. It has a U-shaped mount with a screw pin fixed to a thimble. Along the axis of the thimble is a scale written in millimeters. A screw gauge measures small lengths with accuracy.

A screw gauge has two scales - a key scale and an extra scale. The main scale is a millimeter scale that goes up to 0.5 millimeters, on the other hand, the extra scale (circular scale) is divided into 50 equal parts. The extra scale is on a small metal cap (Rachet) that protects the thimble during screw gauge stitching and measures one-hundredth of the measurement.
The gauge mandible rotates around the spindle. The extra scale on the thimble is also called the vernier rotating scale. In addition, the thimble has been adapted so that two changes of the thimble must move up to 1 mm. This means that a single rotating mandible will move only 0.50 mm. There is a key scale left on the part of the screw gauge called "sleeve".

     

(16) Vernier Caliper

Vernier caliper, a highly accurate linear measuring instrument, was introduced in 1631 by Pierre Vernier of France. It uses two scales: a Main Scale that resembles a ruler and a Vernier Scale, which slides parallel to the main scale and enables readings to be divided into large divisions. Be equal to one part of Vernier calipers are widely used in scientific laboratories and manufacturing for quality control measurement.

The Vernier scale has 25 divisions, while the main scale has 24 divisions of the same length. This means that the division on the Vernier scale is smaller than 25/1 of the division on the main scale.

(17) Coaxial Crimper

 The Coax Strip and Crimp tool is designed to quickly and easily remove the connecting working cable. Ground stripping holes remove the outer jacket and insulation from the RG-59 and RG-6 coaxial cables. This device offers 3 crimping points for both F-category and Ring Terminals.
