Electricity is everywhere: at home, at school, in shops, offices and factories. And there is always a need for someone to install it, test it and repair it: the electrician. The trade combines manual work with precise knowledge, but its most important side is safety. This article introduces the profession: what an electrician does day to day, which fields of work exist, what theory and tools you need, why safety principles sit at the centre of the job, which soft skills matter, how a career is built, how to check whether the trade suits you and which mistakes beginners make. At the end you will find a theory exercise and a checklist.
An important warning: this article does not teach you to do electrical work on your own. Working with electricity is learnt only after proper training, practice and authorisation, under the supervision of an experienced professional. There is a separate article on using electricity safely at home: electrical safety at home.
Who is an electrician and what do they do
An electrician is a specialist who installs, commissions, tests and repairs electrical networks and equipment. The work falls into several main types.
Wiring in homes and buildings
In a house or flat that is being built or renovated: planning cable routes, laying cable, fitting sockets and switches, and dividing the rooms into separate circuits. For example, powerful kitchen appliances get a dedicated circuit, because they put a heavier load on it than the lighting circuit does.
Lighting
Installing and repairing lighting in rooms, corridors, stairwells, streets and courtyards. Today old lamps are being replaced with energy-efficient fittings in many places, and lighting controlled by motion sensors and timers is also common.
Sockets, circuit breakers and the distribution board
The distribution board is the “control centre” of a flat or building. It holds the circuit breakers, residual current devices and the meter. An electrician assembles the board, labels each circuit and draws up its diagram. On a well-built board, every breaker has a label showing which room it serves.
Industrial equipment
In factories and workshops: working with electric motors, pumps, fans, machine tools and their control cabinets. The work here is more complex and the responsibility greater.
Repair and maintenance
Finding faults (“why is the light not working in this room?”), replacing worn parts and carrying out regular preventive inspections. For example, Sardor, the electrician in a school’s facilities team, inspects the distribution boards every month, notes any connections that have overheated or worked loose, and reports them to the person in charge.
Fields of work
Electricians work in many different sectors, and over time many of them specialise in one field.
- Construction installation. Wiring new homes, schools, offices and shops from scratch. The work follows a project design and is coordinated with the other builders.
- Operation and maintenance. Looking after an existing building on an ongoing basis: for a homeowners’ association, a hospital, school, shopping centre or hotel. The main task is to keep the network running safely and without interruption.
- Industry. Working with motors, pumps and automation at a plant, factory, greenhouse complex or agricultural business.
- New fields. Solar panels and their systems, energy-efficient lighting, smart home devices, charging points for electric vehicles. These fields require extra training, but the foundation is the same: understanding the network and safety.
The ways of working vary too: a staff employee of an organisation, a member of a construction crew or, once you have gained experience, an independent tradesperson. Remember that even when working independently, you must follow the official requirements and permits.
Essential knowledge: current, voltage and diagrams
Being good with your hands is not enough for an electrician; you also need to understand the theory. Here are the key concepts in plain language.
Voltage, current and resistance
- Voltage (U, volts) is the force that “pushes” electric charges. You can compare it to the water pressure in a pipe. In a household network it is usually around 220 volts.
- Current (I, amperes) is the amount of electricity flowing through a conductor, much like the flow of water in a pipe.
- Resistance (R, ohms) is how much a conductor or device “resists” the current, much like the narrowness of a pipe.
The relationship between them is expressed by Ohm’s law: I = U / R. In other words, when voltage rises, current increases, and when resistance rises, current decreases. A hypothetical example: with 12 volts and 4 ohms, the current is 3 amperes. This formula explains why the cable size and the breaker rating must be matched to the load: excess current heats the cable.
Live, neutral and earth
A household network usually has three conductors:
- Live (phase): the conductor that carries the voltage, and the most dangerous one.
- Neutral: the conductor the current returns through.
- Earth (protective conductor): if a fault puts voltage on the casing of an appliance, it sends the current along a safe path.
The conductors are distinguished by the colour of their insulation, but in older buildings the colours may not follow the rules. That is why a professional never relies on colour alone and always checks by measuring.
Reading diagrams
A wiring diagram is the “map” of the network: which breaker supplies which sockets and lights, and where the cables run. Each element on the diagram is shown by a standard symbol: switch, socket, lamp, breaker, earth. Being able to read diagrams is a core part of any training programme, because without it neither installation nor fault-finding can be done properly.
In addition, an electrician needs to understand the basics of measurement, materials (types of cable, terminals, protective devices) and technical documentation. All of these are the trade’s hard skills.
Tools and what they are for
An electrician’s tools are part of their safety. Below are the main tools and what they are for; how to use them is learnt in practical classes under a supervisor’s eye.
- Multimeter: an instrument for measuring voltage, current and resistance. It is used to check whether a line is live and whether a conductor is broken.
- Voltage indicator and test screwdriver: for quickly finding out whether voltage is present. A test screwdriver gives only a rough indication; for a reliable check, professionals use a proper voltage indicator or measuring instrument.
- Insulated tools: screwdrivers, pliers and cutters with handles covered in a special insulating layer. Telling an ordinary tool from an insulated one is one of the first lessons of the trade.
- Wire stripper: for removing cable insulation without damaging the conductor.
- Terminals and connectors: for joining conductors securely. A poor connection heats up and can cause a fire.
- Protective equipment: dielectric gloves, workwear, safety glasses, an insulating mat, warning signs and locks.
- Auxiliary tools: a hammer drill, spirit level, tape measure, torch and a cable-pulling tool.
Choosing tools for their quality and keeping them clean and in good condition is part of the professional culture. A tool with cracked insulation is a dangerous tool.
Safety: the heart of the trade
Electricity is invisible, has no smell and gives no warning. That is why safety in this trade is not an “extra rule” but its very core. As experienced electricians say, people who rush do not last long in this job. Below are the general principles. The specific requirements, standards and procedures are set out in official documents; you will learn them during training and in the workplace, and follow them strictly.
Key principles
- Work is done with the power switched off. The relevant circuit is isolated using a breaker or another switching device.
- Isolation is confirmed by testing. The assumption “I switched off the breaker, so there is no power” is dangerous: the breaker may be mislabelled, or the circuit may be fed from somewhere else. The test instrument itself is also checked beforehand to make sure it works.
- The power cannot be switched back on by accident. A warning sign is hung on the isolated device and, where possible, it is locked off. Otherwise someone else could restore the power without realising.
- Protective equipment is used. Insulated tools, gloves, workwear and other equipment, every single time, even for a “one-minute job”.
- Dangerous work is never done alone. A second person must be nearby who can see what is happening and help if needed.
- When in doubt, stop. If the diagram is unclear, a connection looks odd or an instrument seems unreliable, the work stops and you ask a supervisor or an experienced colleague for advice.
Authorisation and safety qualification levels
In many organisations, staff are authorised to work on electrical installations only after their training and knowledge have been checked. This uses the idea of an electrical safety qualification group: depending on how much training someone has had, how much experience they have and whether they have passed a knowledge test, they are permitted to carry out certain types of work. Knowledge is re-tested periodically. The exact procedure depends on the requirements of the organisation and the sector, so be sure to familiarise yourself with them when you start a job, and work only within the official requirements and permits.
Keep this in mind too: deciding “I’ll just replace the socket at home myself” without professional training is dangerous. An untrained person should not do electrical work on their own but should call a qualified professional.
Soft skills and working with customers
An electrician works not only with cables and tools but also with people. That is why soft skills matter as well.
- Precision and order. Every breaker on the board is labelled, cable routes are recorded and the work area is left clean. Whoever comes after you must be able to understand everything.
- Responsibility. The consequences of a mistake are serious: a faulty connection can go unnoticed for months and then cause a fire.
- Talking to customers. Explaining in simple terms what will be done, why a particular solution was chosen and how long it will take. For example, Dilshod, an electrician, explains to the homeowner, Gulnora opa, why the old wiring needs to be replaced completely: the insulation has become brittle and the connections have been overheating.
- Explaining the estimate. Listing which materials are needed, how much of each and why. When the customer understands every item, trust grows.
- Teamwork. On a building site, you need to agree the order of work with the plumber, plasterer and builders.
- Honesty. Saying “I don’t know, I’ll check and get back to you” is better than giving a wrong answer.

Career path and whether the trade suits you
A typical career path
- Training. A vocational college, a training course or programme: theory, diagrams, safety and getting to know the tools.
- Practice. Working as an assistant to an experienced electrician: first pulling cable and preparing materials, then, under supervision, more complex tasks. This stage can last a long time, and there is no need to rush it.
- Independent work. Once you have enough experience and the necessary authorisation, certificate or documents: independent tasks, and later leading a crew or running your own business.
- Development. Further training in fields such as industrial automation or solar energy.
For example, Bekzod from Samarkand took a training course after school, then worked alongside an experienced electrician in a construction crew, and once he had gained experience, joined the maintenance department of a shopping centre. When applying for jobs, it is important to describe your training and practical experience clearly; see the article on writing a CV.
Questions to ask yourself
- Do you enjoy working with your hands, building and fixing things?
- Are you ready to follow rules strictly, even when you are in a hurry?
- Can you patiently search for the cause of a fault?
- Are you willing to study the basics of physics and maths?
- Are you comfortable working in different places, sometimes at height or in a basement?
- Can you tell colours apart well? This matters when working with conductors.
If you answered “yes” to most of these questions, the trade may suit you. For a general approach, read choosing a profession, and if you want to move from another field, changing careers.
Common beginner mistakes
- Not testing for voltage. Starting work without measuring because “I switched it off” is the most dangerous mistake of all.
- Rushing. Skipping safety steps to finish faster.
- Trusting colours. In an older building, a conductor’s colour may not follow the rules.
- Using ordinary tools. Working with uninsulated or damaged tools.
- Not labelling. Leaving breakers and cables on the board unlabelled, so nobody can make sense of them later.
- Poor connections. A loosely tightened terminal heats up and creates a fire risk.
- Not asking about what you don’t understand. Being too shy to ask questions is the biggest loss during your practice period.
- Working without authorisation. Taking on work beyond your qualification and authorisation.
Practical exercise and checklist
This exercise is purely theoretical: do not touch any electrical installation.
- Reading a diagram. Find a sample wiring diagram for a flat online or in a textbook. Write down how many circuits it has, which breaker supplies which rooms and which symbols are used.
- Look at the board in your home (without opening it). Are the breakers labelled? If not, write down for yourself why that could be a problem.
- A list of tools. Make a list of tools and protective equipment for a beginner electrician, and write one sentence on why each is needed.
- The safety sequence. Write down from memory, in the correct order, the key principles to follow before starting work, and compare your list with this article.
- Explaining to a customer. A hypothetical situation: a customer asks why the old wiring needs replacing. Write a simple answer of 4–5 sentences.
