According to the Bureau of Labor Statistics (“BLS”), the U.S. Department of Labor’s principal fact- finding agency for the federal government in the field of labor, economics, and statistics that provides data on employment and wages, Line Installers and Repairers, also known as line workers, install or repair electrical power systems and telecommunications cables, including fiber optics.
They install and maintain the power grid—the network of power lines that moves electricity from generating plants to customers. They routinely work with high-voltage electricity, which requires extreme caution. The electrical current can range from hundreds of thousands of volts for long-distance transmission lines that make up the power grid to less than 10,000 volts for distribution lines that supply electricity to homes and businesses.
Line workers who maintain the interstate power grid work in crews that travel to locations throughout a large region to service transmission lines and towers. Workers employed by local utilities work mainly with lower voltage distribution lines, maintaining equipment such as transformers, voltage regulators, and switches. They also may work on traffic lights and street lights.
