Electricity is essential for light, power, air-conditioning, and
refrigeration. Electricians install, connect, test, and maintain electrical
systems for a variety of purposes, including climate control, security, and
communications. They also may install and maintain the electronic controls for
machines in business and industry. Although most electricians specialize in
construction or maintenance, a growing number do both.
Electricians work with blueprints when they install electrical systems in
factories, office buildings, homes, and other structures. Blueprints indicate
the locations of circuits, outlets, load centers, panel boards, and other
equipment. Electricians must follow the National Electric Code and comply with
State and local building codes when they install these systems. In factories and
offices, they first place conduit (pipe or tubing) inside designated partitions,
walls, or other concealed areas. They also fasten to the walls small metal or
plastic boxes that will house electrical switches and outlets. They then pull
insulated wires or cables through the conduit to complete circuits between these
boxes. In lighter construction, such as residential, plastic-covered wire
usually is used instead of conduit.
Regardless of the type of wire used, electricians connect it to circuit
breakers, transformers, or other components. They join the wires in boxes with
various specially designed connectors. After they finish the wiring, they use
testing equipment, such as ohmmeters, voltmeters, and oscilloscopes, to check
the circuits for proper connections, ensuring electrical compatibility and
safety of components.
Electricians also may install low voltage wiring systems in addition to
wiring a building’s electrical system. Low voltage wiring involves voice,
data, and video wiring systems, such as those for telephones, computers and
related equipment, intercoms, and fire alarm and security systems. Electricians
also may install coaxial or fiber optic cable for computers and other
telecommunications equipment and electronic controls for industrial equipment.
Maintenance work varies greatly, depending on where the electrician is
employed. Electricians who specialize in residential work may rewire a home and
replace an old fuse box with a new circuit breaker box to accommodate additional
appliances. Those who work in large factories may repair motors, transformers,
generators, and electronic controllers on machine tools and industrial robots.
Those in office buildings and small plants may repair all types of electrical
equipment.
Maintenance electricians spend much of their time doing preventive
maintenance. They periodically inspect equipment, and locate and correct
problems before breakdowns occur. Electricians may also advise management
whether continued operation of equipment could be hazardous. When needed, they
install new electrical equipment. When breakdowns occur, they must make the
necessary repairs as quickly as possible in order to minimize inconvenience.
Electricians may replace items such as circuit breakers, fuses, switches,
electrical and electronic components, or wire. When working with complex
electronic devices, they may work with engineers,
engineering technicians, or industrial
machinery installation, repair, and maintenance workers. (Statements on
these occupations appear elsewhere in the Handbook.)
Electricians use handtools such as screwdrivers, pliers, knives, hacksaws,
and wire strippers. They also use a variety of power tools as well as testing
equipment such as oscilloscopes, ammeters, and test lamps.
Electricians’ work is sometimes strenuous. They bend conduit, stand for
long periods, and frequently work on ladders and scaffolds. Their working
environment varies, depending on the type of job. Some may work in dusty, dirty,
hot, or wet conditions, or in confined areas, ditches, or other uncomfortable
places. Electricians risk injury from electrical shock, falls, and cuts; to
avoid injuries, they must follow strict safety procedures. Some electricians may
have to travel great distances to jobsites.
Most electricians work a standard 40-hour week, although overtime may be
required. Those in maintenance work may work nights or weekends, and be on call.
Maintenance electricians may also have periodic extended overtime during
scheduled maintenance or retooling periods. Companies that operate 24 hours a
day may employ three shifts of electricians.
Electricians held about 659,000 jobs in 2002. More than one-quarter of wage
and salary workers were employed in the construction industry; while the
remainder worked as maintenance electricians employed outside the construction
industry. In addition, about one in ten electricians were self-employed.
Because of the widespread need for electrical services, jobs for
electricians are found in all parts of the country.
Most people learn the electrical trade by completing an apprenticeship
program lasting 3 to 5 years. Apprenticeship gives trainees a thorough knowledge
of all aspects of the trade and generally improves their ability to find a job.
Although electricians are more likely to be trained through apprenticeship than
are workers in other construction trades, some still learn their skills
informally on the job. Others train to be residential electricians in a 3-year
program.
Apprenticeship programs may be sponsored by joint training committees made
up of local unions of the International Brotherhood of Electrical Workers and
local chapters of the National Electrical Contractors Association; company
management committees of individual electrical contracting companies; or local
chapters of the Associated Builders and Contractors and the Independent
Electrical Contractors Association. Because of the comprehensive training
received, those who complete apprenticeship programs qualify to do both
maintenance and construction work.
The typical large apprenticeship program provides at least 144 hours of
classroom instruction and 2,000 hours of on-the-job training each year. In the
classroom, apprentices learn blueprint reading, electrical theory, electronics,
mathematics, electrical code requirements, and safety and first aid practices.
They also may receive specialized training in welding, communications, fire
alarm systems, and cranes and elevators. On the job, under the supervision of
experienced electricians, apprentices must demonstrate mastery of the
electrician’s work. At first, they drill holes, set anchors, and set up
conduit. Later, they measure, fabricate, and install conduit, as well as
install, connect, and test wiring, outlets, and switches. They also learn to set
up and draw diagrams for entire electrical systems.
After finishing an apprenticeship, journeymen often continue to learn about
related electrical systems, such as low voltage voice, data, and video systems.
Many builders and owners want to work with only one contractor who can install
or repair both regular electrical systems and low voltage systems.
Those who do not enter a formal apprenticeship program can begin to learn
the trade informally by working as helpers for experienced electricians. While
learning to install conduit, connect wires, and test circuits, helpers also
learn safety practices. Many helpers supplement this training with trade school
or correspondence courses.
Regardless of how one learns the trade, previous training is very helpful.
High school courses in mathematics, electricity, electronics, mechanical
drawing, science, and shop provide a good background. Special training offered
in the U.S. Armed Forces and by postsecondary technical schools also is
beneficial. All applicants should be in good health and have at least average
physical strength. Agility and dexterity also are important. Good color vision
is needed because workers frequently must identify electrical wires by color.
Most apprenticeship sponsors require applicants for apprentice positions to
be at least 18 years old, have a high school diploma or its equivalent, and be
able to pass a skills test. For those interested in becoming maintenance
electricians, a background in electronics is increasingly important because of
the growing use of complex electronic controls on manufacturing equipment.
Most localities require electricians to be licensed. Although licensing
requirements vary from area to area, electricians usually must pass an
examination that tests their knowledge of electrical theory, the National
Electrical Code, and local electric and building codes. Electricians
periodically take courses offered by their employer or union to keep abreast of
changes in the National Electrical Code, materials, or methods of installation.
Experienced electricians can become supervisors and then superintendents.
Those with sufficient capital and management skills may start their own
contracting business, although this may require an electrical contractor’s
license. Many electricians become electrical inspectors.
Job opportunities for electricians are expected to be good. Numerous
openings will arise each year as experienced electricians leave the occupation.
In addition, many potential workers may choose not to enter training programs
because they prefer work that is less strenuous and has more comfortable working
conditions.
Employment of electricians is expected to grow
faster than the average for all occupations through the year 2012. As the
population and economy grow, more electricians will be needed to install and
maintain electrical devices and wiring in homes, factories, offices, and other
structures. New technologies also are expected to continue to stimulate the
demand for these workers. For example, buildings will be prewired during
construction to accommodate use of computers and telecommunications equipment.
More factories will be using robots and automated manufacturing systems.
Additional jobs will be created by rehabilitation and retrofitting of existing
structures.
In addition to jobs created by increased demand for electrical work, many
openings will occur each year as electricians transfer to other occupations,
retire, or leave the labor force for other reasons. Because the training for
this occupation is long and difficult and the earnings are relatively high, a
smaller proportion of electricians than of other craftworkers leave the
occupation each year. The number of retirements is expected to rise, however, as
more electricians reach retirement age.
Employment of construction electricians, like that of many other
construction workers, is sensitive to changes in the economy. This results from
the limited duration of construction projects and the cyclical nature of the
construction industry. During economic downturns, job openings for electricians
are reduced as the level of construction activity declines. Apprenticeship
opportunities also are less plentiful during these periods.
Although employment of maintenance electricians is steadier than that of
construction electricians, those working in the automotive and other
manufacturing industries that are sensitive to cyclical swings in the economy
may be laid off during recessions. Also, efforts to reduce operating costs and
increase productivity through the increased use of contracting out for
electrical services may limit opportunities for maintenance electricians in many
industries. However, this should be partially offset by increased job
opportunities for electricians in electrical contracting firms.
Job opportunities for electricians also vary by area. Employment
opportunities follow the movement of people and businesses among States and
local areas, and reflect differences in local economic conditions. The number of
job opportunities in a given year may fluctuate widely from area to area.
In 2002, median hourly earnings of electricians were $19.90. The middle 50
percent earned between $14.95 and $26.50. The lowest 10 percent earned less than
$11.81, and the highest 10 percent earned more than $33.21. Median hourly
earnings in the industries employing the largest numbers of electricians in 2002
are shown below:
Motor vehicle parts manufacturing
$28.72
Local government
21.15
Building equipment contractors
19.54
Nonresidential building construction
19.36
Employment services
15.46
Depending on experience, apprentices usually start at between 40 and 50
percent of the rate paid to fully trained electricians. As apprentices become
more skilled, they receive periodic increases throughout the course of their
training. Many employers also provide training opportunities for experienced
electricians to improve their skills.
Many construction electricians are members of the International Brotherhood
of Electrical Workers. Among unions organizing maintenance electricians are the
International Brotherhood of Electrical Workers; the International Union of
Electronic, Electrical, Salaried, Machine, and Furniture Workers; the
International Association of Machinists and Aerospace Workers; the International
Union, United Automobile, Aircraft and Agricultural Implement Workers of
America; and the United Steelworkers of America.
