Electricians perform a wide range of tasks from wiring new construction to repairing and replacing older systems. They need to have critical thinking skills to perform tests and diagnose problems. And customer service skills to work with customers one-on-one. Mechanical aptitude is also important, as well as being comfortable around electrical work and confident in their abilities. They develop these skills through years of schooling in an apprenticeship program and thousands of hours of hands-on training in the field. Then there’s continuous education and safety training to stay up-to-date on changing codes and conditions.
