Although their responsibilities are pretty much the same, these two professionals have some critical differences. For instance, a commercial electrician works on construction sites for commercial buildings like retail stores, meaning they have to work very early in the morning or late at night to accommodate office hours. Residential electricians, on the other hand, work on homes and apartments.

While these two professionals go through similar education courses, they choose different apprenticeships. Residential electricians will be an apprentice at a tradesperson shop or in an electrician business specializing in residential installations and maintenance. Commercial professionals will work with large electrical systems to prepare them for commercial building projects.
In job responsibilities, commercial electricians work with extra high voltage systems exceeding 240 volts, while residential electricians handle between 120 to 240 volts. The wiring systems in commercial buildings are more prominent, featuring specialized conduits, while residential electricians handle smaller wiring systems with plastic sheathing. This requires them to fit into tight crawlspaces to fit them in.
Residential electricians' policies differ from those required by commercial electricians. Often, commercial electricians have to establish a backup power source to keep facilities like hospitals, law enforcement, and medical laboratories working while they handle electrical issues.
