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 repairers. Electricians also may advise management whether continued operation of equipment could be hazardous. When needed, they install new electrical equipment.
Electricians use handtools such as screwdrivers, pliers, knives, and hacksaws.
They also use power tools and testing equipment such as oscilloscopes, ammeters, and test lamps. Working Conditions Electricians' work is sometimes strenuous. They may stand for long periods and frequently work on ladders and scaffolds. They often work in awkward or cramped positions. Most electricians work a standard 40-hour week, although overtime may be required.
