The vocation of electrician is undoubtedly rewarding provided you keep working hard and honestly. As a professional electrician you may have to cater to your residential clients and work in domestic environments. This is likely to include visiting houses that are in need of electrical repairs. On the other hand you may also have to work in commercial settings. Thus you have to provide support to business establishments or companies. The responsibilities of a domestic electrician often overlap with that of a commercial one although there is a distinct difference in both how and where the two work.  

Therefore it is important for you to understand each role clearly. In the following sections of the blog post let us explore differences between the two categories of electricians.

But a reliable commercial electrician near me in London explains domestic and commercial electricians are the two basic categories. One of the significant differences between these two categories of professionals is the size of projects they usually handle. Even technicality of the projects varies widely among the two.
