Commercial Electrical Contractors

Commercial electrical contractors are those contractors who take contracts on a larger scale. Electrical contractors are known for their work on smaller homes, small shops, or other small buildings. They are responsible for installing and maintaining small-scale electrical systems. Whereas commercial electrical contractors also do the same job besides being responsible for electricity distribution effectively and safely. Electrical contractors are required for newly constructed buildings or buildings where electrical renovation is required.

Responsibilities of a commercial electrical contractor

There are many responsibilities that a commercial electrical contractor must have to do. Some of these responsibilities are as follows:

1. Electrical Planning & Designing

A commercial electrical contractor’s crucial responsibility is that he has to do all the electrical planning for a building. After planning, electrical design making is also the responsibility of an electrical contractor. He plans and design electrical system and do appropriate measures to meet the milestones.

2. Project Management

After planning and designing, the commercial electrical contractor makes sure that all work must be done according to the plan with efficiency and within the timeframe. He must manage all the projects where electrical work is required.

3. Complete the Project  

It is also the responsibility of a commercial electrical contractor that he completes the project on time. Not only does he have to complete the project, but he also has to ensure all the quality standards so that the whole project working is synchronized with common safety standards.

Selection of the right electrician for the right job

The commercial electrical contractor needs a professional workforce for his project. A significant workforce that is necessary for the electrical project is electricians. Choosing the right electrician for the right jobs is very important. Here are some famous electricians.

Electrical Line electricians

These electricians are experts in high voltage power lines and low voltage distribution lines. They know how to handle high and low-voltage power lines very well. High and low voltage lines can be brought to an industrial installation through substations. Electrical line electrician can do this job with efficiency.

Internal Electrician

A commercial electrical contractor has to choose from the above-explained electrician according to his project need and the nature of his commercial project. These are some everyday responsibilities of commercial electrical contractors. If you want to be a commercial electrical contractor, you must prepare your mind for these critical responsibilities.

Residential vs. commercial electrical contractors

With enough time and equipment, any electrician can light up a building. They say that, anyway, until you show them the blueprints for a multistory mall or office building. Electricians are noble professions both on and off the job. There are a lot of overlaps between the two, and both are complex and massively important in their way. Although commercial contractors often work on larger projects, they need to know about residential needs since many electricians work on residential projects.

Every electrician can’t become a contractor, but some more skilled electrician becomes commercial or residential contractors. When an electrician becomes a contractor, they can take their project as a company. This section of the article will discuss the differences between residential and commercial electrical contractors.


Domestic or residential electrical contractors are those contractors who are only responsible for domestic residential electrical systems. Interpreting residential electrical blueprints, repairing domestic electrical machines/ appliances and their parts, and rewiring and inspecting domestic electrical systems are other primary responsibilities of residential electrical contractors.

If we see towards commercial electrical contractors, they will do the same jobs mentioned above, but this time, these jobs get more complex and on a bigger scale. The commercial electrical contractors are responsible for the installation of industrial wiring systems, industrial machines with original diagrams of specific industries. Commercial electrical contractors typically work on commercial buildings, commercial business areas, and factory areas. Another primary service that commercial electrical contractors provide is getting electrical permits for a critical business in big cities.


The second significant difference after residential and commercial electrical contractor service is the power they handle. Residential electrical contractors deal with single-phase low power, which is in between form 140 volts to 240 volts. At the same time, commercial electrical contractors deal with three-phase power supplies between 140 volts to 480 volts. These substantial power supplies differences determine that both contractors used different gear and materials.


Both contractors have to get the same basic training, but when we talk about commercial electrical contractors, they must get advanced level skills because of their work’s complexity. Commercial electrical contractors must gain more experience because of their work’s complex, safety, and reliability factors.

Project magnitude

This is another difference between commercial and residential electrical contractors. The size of a residential electrical contractor is much smaller than the project size of commercial electrical contractors.


The commercial electrical contractor must deal with more complex and larger projects that need many skills and experience. By becoming and commercial electrical contractor, one can earn more and grow more.
