Powerline jobs focus on the installation and repair of power lines. As a lineman or powerline technician, you may use tools to determine if an electric line is live or dead, monitor voltage levels in existing cables, and use equipment provided by a utility company. Most lines are above ground, but some locations use underground power cables, which require additional training and equipment to handle. Aside from the regular day-to-day repairs, powerline jobs also involve working during natural and artificial disasters to repair power lines and get electricity back to people as quickly as possible. You may be asked to work nights, weekends, or holidays as necessary, as well as in hot, cold, or windy conditions. This job is frequently exposed to hazards.
