An electrician is a tradesman specializing in electrical wiring of buildings, stationary machines and related equipment. Electricians may be employed in the installation of new electrical components or the maintenance and repair of existing electrical infrastructure.
Some electricians start out by attending a technical school. Many technical schools offer programs related to circuitry, safety practices, and basic electrical information. Graduates usually receive credit toward their apprenticeship. After completing their initial training, electricians may be required to take continuing education courses. These courses are usually related to safety practices, changes to the electrical code, and training from manufacturers in specific products.
Electricians work indoors and outdoors, in homes, businesses, factories, and construction sites. Because electricians must travel to different worksites, local or long distance commuting is often required. On the jobsite, they occasionally work in cramped spaces, and constant standing and kneeling can be tiring. Those who work in factories are often subject to noisy machinery. As a result, hearing protection must be worn to protect workers from excess noise.
