As a power lineman, your job is to support the operations of utilities by installing and maintaining electrical lines. As part of your role, you may do construction work to fix or replace lines, use equipment to reach areas in need of repair, and teach an apprentice how to do the job. You also identify defective elements in a system, inspect and test power lines and related equipment, climb poles and transmission towers, and work in severe weather conditions. Following disasters like storms or earthquakes, you may work extended shifts if necessary.
