An industrial electrician apprentice trains alongside a journey-level electrician to gain the skills necessary for this career. Apprenticeship programs typically last for four or five years and include classroom work as well as on-the-job training. During your apprenticeship, you help install, repair, and maintain electrical equipment, machinery, and systems at manufacturing facilities and in other industrial settings. You handle your maintenance and repair responsibilities under the supervision of a senior electrician, and your duties vary depending on where you work. Some industrial electricians work outdoors at job sites or electrical facilities, while others work inside of factories or power plants.
