There are a lot of differences between a residential and a commercial electrician. The general job may be the same, but if you ask one, they will disagree entirely that they are the same as the other. Fortunately, there are a few large differences that should clear the confusion between them, and make it easier to tell them apart from each other.
Residential electricians are exactly as named: they are electricians that deal with residential area electricity problems. Their primary focus is single-phase electricity systems ranging between 120 to 240 volts. In terms of specifics, this is much different than a commercial electrician's job.
A commercial electrician is an electrician that works primarily on large commercial buildings, just like the name. They deal with extra-high voltage systems that exceed 240 volts. The systems they work on are also three-phase electrical systems, unlike the residential electrician's single-phase system.
The differences may seem small, but they are important in discerning which type of electrician you should hire for the work you need to be done on your home or business. With this mini-guide, you should be able to hire the right kind of electrician and get the results you need as soon as possible..
