A high school diploma or equivalent is required to become an electrician.

Some electricians start out by attending a technical school. Many technical schools offer programs related to circuitry, safety practices, and basic electrical information. Graduates of these programs usually receive credit toward their apprenticeship.
Most electricians learn through an apprenticeship, but some start out by attending a technical school. Most states require electricians to be licensed. For more information, contact your local or state electrical licensing board.

Electricians typically do the following:

• Read blueprints or technical diagrams
• Install and maintain wiring, control, and lighting systems
• Inspect electrical components, such as transformers and circuit breakers
• Identify electrical problems using a variety of testing devices
• Repair or replace wiring, equipment, or fixtures using hand tools and power tools
• Follow state and local building regulations based on the National Electrical Code
• Direct and train workers to install, maintain, or repair electrical wiring or equipment.

Almost every building has an electrical power, communications, lighting, and control system that is installed during construction and maintained after that. These systems power the lights, appliances, and equipment that make people’s lives and jobs easier and more comfortable.

Installing electrical systems in newly constructed buildings is often less complicated than maintaining equipment in existing buildings because electrical wiring is more easily accessible during construction. Maintaining equipment and systems involves identifying problems and repairing broken equipment that is sometimes difficult to reach. Maintenance work may include fixing or replacing parts, light fixtures, control systems, motors, and other types of electrical equipment.

Electricians read blueprints, which include technical diagrams of electrical systems that show the location of circuits, outlets, and other equipment. They use different types of hand tools and power tools, such as conduit benders, to run and protect wiring. Other commonly used tools include screwdrivers, wire strippers, drills, and saws. While troubleshooting, electricians also may use ammeters, voltmeters, thermal scanners, and cable testers to find problems and ensure that components are working properly.

Many electricians work alone, but sometimes they collaborate with others. For example, experienced electricians may work with building engineers and architects to help design electrical systems for new construction. Some electricians may also consult with other construction specialists, such as elevator installers and heating and air conditioning workers, to help install or maintain electrical or power systems. Electricians employed by large companies are likely to work as part of a crew; they may direct helpers and apprentices to complete jobs.

Most electricians learn their trade in a 4- or 5-year apprenticeship program. For each year of the program, apprentices typically receive 2,000 hours of paid, on-the-job training as well as some technical instruction. Workers who gained electrical experience in the military or in the construction industry may qualify for a shortened apprenticeship based on their experience and testing.

Technical instruction for apprentices includes electrical theory, blueprint reading, mathematics, electrical code requirements, and safety and first-aid practices. They may also receive specialized training related to soldering, communications, fire alarm systems, and elevators. Several groups, including unions and contractor associations, sponsor apprenticeship programs. Apprenticeship requirements vary by state and locality.

Some electrical contractors have their own training programs, which are not recognized apprenticeship programs but include both technical and on-the-job training. Although most workers enter apprenticeships directly, some electricians enter apprenticeship programs after working as a helper. After completing an apprenticeship program, electricians are considered to be journey workers and may perform duties on their own, subject to local or state licensing requirements.

Color vision. Electricians must identify electrical wires by color.
Critical-thinking skills. Electricians perform tests and use the results to diagnose problems. For example, when an outlet is not working, they may use a multimeter to check the voltage, amperage, or resistance in order to determine the best course of action.
Customer-service skills. Electricians work with people on a regular basis. They should be friendly and be able to address customers’ questions.
Physical stamina. Electricians often need to move around all day while running wire and connecting fixtures to the wire
Physical strength. Electricians need to be strong enough to move heavy components, which may weigh up to 50 pounds.
Troubleshooting skills. Electricians find, diagnose, and repair problems. For example, if a motor stops working, they perform tests to determine the cause of its failure and then, depending on the results, fix or replace the motor.
