What do they do?

Electrical power line installers and repairers install and maintain the power grid. They routinely work with high voltage electricity that 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 work locations throughout a large region to maintain 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 may also work on traffic lights and streetlights.
