Residential, commercial and industrial electricians have different jobs. All three require a high school diploma, an apprenticeship program, and 8,000-10,000 hours of on-the-job experience. However, a residential electrician uses single phase power supplies, while a commercial electrician frequently performs new construction or installations of lighting, receptacles and transformers. Industrial electricians require specific knowledge of their industry, as a food processing plant is wired differently from an automotive production facility. They maintain everything from micro-currents to high voltage components.

Key Takeaways:

  • A residential electrician needs to have a high school diploma and typically will work in a home or at an apartment.
  • A commercial electrician works in commercial buildings such as retail stores and works frequently doing electrical repairs and installations.
  • An industrial electrician has to know a lot about the manufacturing industry as they work in production facilities installing electrical systems.

“The knowledge bases of residential, industrial and commercial electricians allow them to specialize in three vastly different and equally essential areas of electrical work.”
