Residential and commercial electricians have similar knowledge bases and skill sets, yet they specialize in one discipline. So, what's the difference? In this video, a presenter explains some of the differences between residential and commercial electrician work. One of the focuses of the video is the electric distribution system a home has, compared to that of a commercial property.

While the systems typically look similar, what's in the home is a single-phase system, while commercial properties usually rely on three-phase power. The reason for this is the types of equipment in a traditional commercial property that require a three-phase system. They include things such as welding tools, production equipment and elevators. Homes, on the other hand, don't have such complicated electrical equipment. For this reason, a more cost-effective and simpler system that provides less voltage is sufficient. As explained by the presenter, this is the reason for the divide in the industry between commercial and residential electricity. Electricians choose to focus on one or the other and become familiar with the equipment in their chosen discipline. In addition to explaining the differences between commercial and residential electrician work, this video details elements of commercial electric equipment. The presenter goes from component to component and shows what it takes to power a traditional commercial facility. He also provides useful information about ownership and responsibility in regard to commercial electrical equipment.
