The Differences Between Residential and Commercial Electrical Services

What are some principal differences between commercial and residential
electrical services you should be aware of?

When it comes to electrical services, “one size fits all approach” is not suitable, since there are some significant differences between residential and commercial electrical services, and not every electrician is qualified to do both types of work.

Each type of these tasks requires different skillset, techniques, equipment, and is governed by different legislation. Knowing the differences will help you choose a specialized company or expert for your specific job, which will ultimately result in a better-quality service for you.

Residential works involve working with households, whereas commercial work can take place on anything from shops to factories, and public buildings etc. The differences between residential electricians and commercial specialists, are mainly technical.

Some of the essential differences between commercial and residential services include different levels of energy demands, different category or quality of materials, and different environments where wiring is installed.

Residential wiring is typically plastic sheathed wiring and normally doesn’t use conduits. In commercial construction, conduit is always used.

Another difference is the power from the utility company – it varies greatly between residential and commercial applications. Homes use single-phase power with two 120-volt wires and a neutral wire. Commercial buildings use three-phase power with two 120-volt legs, one 208-volt leg and a neutral wire. Commercial electrical applications require power demands for larger electrical units and three-phase power enables power to flow more smoothly to needed areas.

The quality, or grade, of electrical materials also differs between residential and commercial buildings. Commercial materials are more resistant to heat, corrosion, and chemical exposure. They are subject to different standards, and are governed by different codes. Some commercial buildings, such as hospitals, need a secondary or backup source of power with the ability to withstand more demanding usage.

In case of commercial projects, electricians may consult with architects, designers, and contractors in the course of their work. The latter look at a project from a broader perspective and may provide detailed drawings and plans for electrical installations. Residential electrical projects do not normally need this.

There are also differences in the electricians who are qualified to work on commercial versus residential buildings and how they are licensed. When looking for an electrician for your specific project make sure that the specialist you hire has all the necessary credentials and is well positioned to do the job. Commercial electricians are better positioned to take on more sophisticated and larger scale projects.

Some electricians, however, such as at 911 Plumbing and Electrical INC., are experienced at new commercial construction, renovations, and have worked on multiple projects. We have multi-faceted experts and are well positioned to do job on both residential and commercial sides.
