Electrical technicians install wiring, circuits, outlets, lighting fixtures, and other devices that use electricity in homes, commercial buildings, or industrial spaces. They also repair and maintain existing systems. They may work on power lines, lighting fixtures, switchgear, conduits, and solar photovoltaic cells.

They need good problem-solving skills to correctly assess and repair issues with light fixtures, outlets, and electrical wiring. They often use test equipment to measure voltage levels and trace electrical pathways to find the source of problems. They also have strong communication skills to interact with customers and other professionals on the jobsite.

Many electricians are self-employed and operate their own businesses, but some are employed within an electrical company or organization. The latter option provides them with a steady stream of income and helps them build business relationships with clients. Regardless of how they are employed, they need to have a valid electrical contractor’s license to perform their work. They should be insured and bonded, too.

Choosing an electrician to work on your home improvement project is a big decision. Word of mouth is a great way to find a reliable professional, but you can also check online reviews and testimonials. Make sure the pro is licensed and has a proven track record with satisfied customers. Also, ask about a labor warranty. These plans cover parts and labor for a specific period of time after the initial installation.

Electricians need a high school diploma or equivalent, and they receive their training on the job. Many enter the profession through an apprenticeship program lasting four to five years. Apprentices must pass a background check and drug screening to qualify for the position.

Some electricians specialize in particular areas of the industry, such as industrial or residential. These specializations can affect the types of projects they are responsible for and the tools and materials they use. For example, an industrial electrician might work on high-voltage machinery in a factory, while a residential electrician might specialize in installing and maintaining home entertainment systems. Regardless of their specialty, all electricians must be competent at working with their hands and arms to handle wires, cables, and other mechanical components.


Like any other machine, electrical systems require yearly check-ups and daily maintenance to stay in good condition. Performing regular electrical maintenance keeps your system in top shape, prevents problems from getting worse and saves you money.

In residential homes, electricians can help homeowners keep their electrical systems in good condition by conducting load assessments and installing surge protection devices. These devices protect sensitive electronic equipment from power spikes that can damage appliances and even cause fires.

Electricians also install and service home wiring. This can involve adding outlets and switches, rewiring outdated circuits or replacing worn out wiring. They can also perform simple repairs that don’t require a lot of manual dexterity, such as replacing burned-out light bulbs or testing for loose connections on switches and wires using a multimeter.

Commercial and industrial buildings also have large electrical systems that must be maintained to ensure continued operation of equipment, lights and machinery. In these settings, electricians often work in collaboration with engineers and maintenance personnel to maintain the safety of high-voltage equipment and electrical systems. Maintenance electricians regularly inspect building specifications, wiring and equipment diagrams to look for any issues that could affect productivity.

These electrical professionals are often trained in specific sub-specialties that focus on the type of equipment they maintain. For example, industrial electricians may work on machines that make products at factories or in hospitals and office buildings, while electrical maintenance technicians typically inspect and repair lighting and air-conditioning systems. In addition, electrical linemen work on electricity transmission systems and the higher voltages used outdoors, while inside wiremen focus on the lower-voltage wiring found indoors.

Aside from electrical maintenance, electricians can also provide routine inspections of power lines and other electrical infrastructure to detect any issues that could cause outages or fires. This can be particularly important in places of business, where a loss of power can halt operations and cost companies millions of dollars.

As an electrician, you’ll need to maintain excellent communication skills. This is because customers rely on you to keep them updated throughout the project, from start to finish. Keeping the lines of communication open will help you resolve any issues as quickly and efficiently as possible.


An electrician’s job is to inspect and repair electrical systems, equipment, and machinery in a variety of environments. They follow a device’s schematics and use specialized measuring tools to identify any problems or issues with the design or build. This can include fixing wiring, circuits, outlets, or switches. Electricians also work on motor vehicles to fix or maintain their electrical components. These tradespeople must often work in confined spaces and in harsh conditions. They must also be comfortable working with high-voltage electricity to prevent burns or arc-flash injuries.


Electrical inspection and testing is a vital part of any electrician’s job. It allows them to make sure that all electrical systems are safe to use and comply with BS7671 regulations. It can also help to prevent electric shocks and fires. It is important that an electrician has the right knowledge and training to carry out electrical inspection and testing effectively.

An electrician needs to have good communication skills, as they will often be working with people from different backgrounds and industries. They will need to be able to explain complex electric issues in ways that non-electricians can understand. They will also need to be able to work well as part of a team, especially if they are working on larger electrical projects or in facilities management.

They should be able to identify problems and provide recommendations on how best to fix them. This will require a strong understanding of engineering and maths, including calculations for currents, voltages, cable lengths, and more. It is also important that they can read and interpret technical manuals, drawings, and documents.

It is essential that an electrician has the correct equipment to test all types of electrical installations, such as RCD switches, power and earth connections, and plug sockets. They should also have the ability to use simple test lights, which will indicate whether or not there is a power supply to a circuit. They should be able to detect any faults or potential hazards, such as overloading, which can cause damage to electrical appliances and lead to fires.

To become a qualified electrician, it is necessary to complete an apprenticeship and pass an examination. Exams typically include questions on the NEC, theoretical questions, and questions related to local laws and regulations. To pass the exam, it is crucial to study thoroughly and plan ahead. It is a good idea to create notes or tabs for important sections of the book and to practice under timed conditions. It is also a good idea to take note of how long it takes to answer each question, so that you can pace yourself.
