Electrical tools are the most common and simple form of engineering tools. A screwdriver neon tester and pliers are specially used for electrical lighting and wiring in homes, offices, courts, shops and industries. Also used electrical loads such as lights, fans, motors and other home appliances require different types of hand tools, power tools and measuring instruments. Besides, measuring tools are required for measuring something. The importance of purchasing good quality tools for the convenience of work is immense.
Definition of Electrician Hand tools:- Hand tools means equipment used in manual work. All the tools that can be used to solve technical work easily by applying physical force are called hand tools. All the tools used by an electrician in electrical work are called electrician hand tools.
Importance and necessity of common hand tools: Without hand tools, no work can be done beautifully, properly, with just hands. In electrical work, an engineer or a skilled electrician needs hand tools to do his work properly and properly. The importance and need of hand tools to work properly while maintaining the quality of work is immense as well as the need for maintenance. If hand tools are not properly maintained, their effectiveness is lost, so the quality of work cannot be maintained with those tools. Accidents occur without hand tools to connect and disconnect electrical lines while they are live. Therefore, the importance and necessity of common hand tools is immense to solve the technical activities properly, beautifully and perfectly.

Functional description of electric hand tools:- Below are the descriptions of 10 hand tools used in electrical work:-
1. Neon Tester:- These types of hand tools are used to detect the presence of electricity and phase wires.
2. Measuring tape:- This type of measuring tape is used to accurately measure the length, width and height of an object while working.
3. Flat Screw Driver:- Flat screw driver is an important hand tool. It is used to open or install wooden screws or machine screws. Because its tip is flat or flat, it is called a flat screwdriver.
4. Phillips Screw driver:- Phillips screwdriver is also an important hand tool. It is used to open or engage the slot (+)cross shape on the tip of machine screws. As its tip (+) is cross shaped, it is called a Phillips screwdriver.
5. Combination Pliers:-It is an important hand tool for general technical work. It is used for cutting, wrapping and gripping.
6. End Cutting Pliers:- It is generally used for cutting the end of a wire.
7. Wire Stripping Pliers:- Generally Wire Stripping Pliers are used to remove the insulation on the wire.
8. Electric Hand Drill Machine:- It works like a normal hand drill, but it is powered by electricity.
9. Ball pin Hammer:- It is a simple hammer with one end shaped like a round ball and the other end flattened. It is used for roasting or bending or beating metallic materials into different shapes.
10. Bench Vice:- Vise serves as an important auxiliary tool in technical work. A bench vise is used to hold a job firmly.
11. Electric soldering iron:- Electric soldering iron is used for smoothing electrical joints.
12. Round Nose Pliers:- Round nose pliers are generally used for ringing or bending a wire. Screw
Concept of Power Tools: All the work that cannot be done by hand tools can be done by power tools. Power tools are used for drilling or cutting holes in a wall, leveling/smoothing uneven jobs, tightening joints and cutting wood.
Concept of Measuring Instruments:- All the tools or instruments used to measure the value of any object or quantity are measuring tools or measuring instruments. Different types of scales are used for measuring length, width, just like different types of meters are used for measuring electrical quantities.
Electrical Measuring Instruments:- Various types of meters for measuring Electric amount are discussed below:-
(1). Ammeter: The meter with which current is measured is called ammeter. Ammeter is used to measure the current in a circuit. It gives value in ampere unit.
(2). Volt-Meter: The meter used to measure voltage is called volt-meter. It measures voltage in volts.
(3). Ohm Meter: The meter used to measure resistance is called Ohm-meter. With this resistance is measured in Ohm unit.
(4). Multi-Meter: The meter used to measure current, voltage and resistance etc. is called multi-meter. With its help current, voltage and resistance etc. are measured.
(5). Watt Meter: A meter used to measure electrical power is called a watt-meter. Power is measured in watts.
(6). Clip On Meter: A meter that measures current by clamping is called a clip on meter. It can measure current, voltage and resistance.
(7). Energy Meter: The meter with the help of which energy is measured is called energy meter. With this, the electricity bill is available in unit form.
(8). Power Factor Meter: The meter that measures the power factor of an AC circuit is called a power factor meter. It measures the power factor.
(9). Lux Meter: The meter used to measure light intensity is called lux meter. It measures the intensity of light.
(10). Frequency Meter: The meter used to measure the frequency of an AC circuit is called a frequency or Hertz meter. The frequency of AC supply is measured with the help of frequency meter.
(11). Taco Meter: The meter that measures the rotational speed of the motor is called a tachometer. The rotation of the motor is measured in RPM with the help of tachometer.
(12). Megger: The meter used to measure the insulation resistance of a cable is called Megger. With this, insulation resistance is measured in mega ohms.
(13). Earth Tester: The meter used to measure earth resistance is called earth tester. With this earth resistance is measured in ohms.
