Apprentice linemen learn to build and maintain the electrical power line systems. They work in an industry that builds the entire job from start to finish. The activities of a Journeyman Lineman are diversified and non-routine. An apprentice will learn and master many skills, and will have the satisfaction of working with a team to complete a project. The duties of the Apprentice lineman include everything necessary to bring power from its’ origination point to the end user. Linemen often assemble and erect metal towers and wood poles along with the installing footings, hardware, conductors and other related equipment. They perform work on conductors, underground cables, and related electrical apparatus possibly energized at voltages up to 500,000 volts. Climbing, lifting, hoisting, and pulling, while installing or repairing equipment, often at considerable heights are a large part of lineman work. The work is physically demanding on all kinds of terrain and in extreme weather conditions from freezing blizzard conditions to temperatures over 100 degrees. The program generally takes about four years to complete, and will require extensive travel. The program consists of a minimum of 7000 hours of on-the-job training and related instructional classes, generally held on Saturdays. Apprentices are assigned to a full time job and earn wages while learning the trade. There is no compensation for the related instructional classes. Current trends and changes in the industry fueled by de-regulation provide optimism for steady growth and reliable employment opportunities in the future, especially in the construction branch of the trade.
