INTRODUCTION An electrician is a tradesperson 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. Electricians may also specialize in wiring and cables. Electricians work in a variety of settings, including homes, industries, schools, hotels, workshops and hospitals-any type of facility that needs electricity to function. Working conditions for electricians vary by specialization. Generally an electrician's work is physically demanding such as climbing ladders and lifting tools and supplies. Occasionally an electrician must work in a cramped space or on scaffolding, and may frequently be bending, squatting or kneeling, to make connections in awkward locations. Construction electricians may spend much of their days in outdoor or semi-outdoor noisy and dirty worksites. Industrial electricians may be exposed to the heat, dust, and noise of an industrial plant. Power systems electricians may be called to work in all kinds of adverse weather to make emergency repairs.
