What Do Electricians Do?
Skills needed to become an electrician include manual dexterity, eye-hand coordination, physical fitness, and a good sense of balance. The ability to solve arithmetic problems quickly and accurately also is required. Good color vision is needed because workers frequently must identify electrical wires by color. In addition, a good work history or military service is viewed favorably by apprenticeship committees and employers.
Electricians work with blueprints when they install electrical systems. Blueprints indicate the locations of circuits, outlets, load centers, panel boards, and other equipment. Electricians must follow the National Electrical Code and comply with State and local building codes when they install these systems. Regulations vary depending on the setting and require various types of installation procedures.
Electricians generally specialize in construction or maintenance work, although a growing number do both. Electricians
specializing in construction work primarily install wiring systems into new homes, businesses, and factories, but they also rewire or upgrade existing electrical systems as needed. Electricians specializing in maintenance work primarily maintain and upgrade existing electrical systems and repair electrical equipment.
When electricians install wiring systems in factories and commercial settings, they first place conduit (pipe or tubing) inside partitions, walls, or other concealed areas as designated by the blueprints. They also fasten to the walls small metal or plastic boxes that will house electrical switches and outlets. They pull insulated wires or cables through the conduit to complete circuits between these boxes. In residential construction, electricians usually install plastic encased insulated wire, which does not need to be run through conduit. The gauge and number of wires installed in all settings depends upon the load and end use of that part of the electrical system. The greater the diameter of the wire, the higher the voltage and amperage that can flow through it.
Electricians connect all types of wire to circuit breakers, transformers, outlets, or other components. They join the wires in boxes with various specially designed connectors. During installation, electricians use hand tools such as conduit benders, screwdrivers, pliers, knives, hacksaws, and wire strippers, as well as power tools such as drills and saws. After they finish installing the wiring, they use testing equipment, such as ammeters, ohmmeters, voltmeters, and oscilloscopes, to check the circuits for proper connections, ensuring electrical compatibility, and safety of components.
Job Outlook for Electricians
Employment of electricians is expected to increase as fast as average for all occupations through the year 2014. 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 need to increasingly accommodate the use of computers and telecommunications equipment. Also, the increasing prevalence in factories of robots and other automated manufacturing systems will require more complex wiring systems be installed and maintained. Additional jobs will be created as older structures are rehabilitated and retrofitted, which usually requires that they be brought up to meet existing electrical codes.
In addition to jobs created by the increased demand for electrical work, many openings are expected to occur over the next decade as a large number of electricians are expected to retire. This will create good job opportunities for the most qualified jobseekers. Job openings for electricians, though, will vary by area and will be greatest in the fastest growing regions of the country.
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.
