A wiring technician or line worker works on the installation and maintenance of wire or cable for electrical power. In this career, you troubleshoot issues involving transformers, voltage regulators, or other equipment, including the towers and poles that support them. Your responsibilities often put you in dangerous situations. Your duties also concern the upkeep of the components of the power grid, replacing older ones as necessary. Most find employment as a wiring technician with a utility company, but a construction business or the local government is another possible source. Safety training with fall protection equipment is imperative. Work is full-time, but you may get overtime in the aftermath of natural disasters or emergencies.
