differences between residential and commercial electrical services.

Residential and commercial electrical services are completely different in terms of equipment setup,
load demands, and energy needs. From the load and energy requirements to the grade of material
used, these services can vary very differently. Even the installation process involved is vastly different.
For your understanding, here are some differences between residential and commercial electrical
services to guide you in your search.


The installation of electrical wires is an important function of an electrician. The type of wiring utilized
for each type of building is one major difference between residential and commercial electrical
installation. It’s easy to find thin, narrow wires with plastic sheathing around them in residential
homes. this
will help to protect the wiring. The sheathing can also help to protect any surround materials.

In a bid to allow access, the electrical wiring can be run in open spaces. As a result, it does require a higher
level of insulation. In order to ensure full protection from corrosive substances, a TTHT insulation will
be required for commercial wiring. This refers to thermoplastic, high-heat resistant, nylon coated.

Power Phases

These three wires consist of the neutral, the positive, and negative lines.To this end, a single phase circuit of 120 volts would be appropriate. However, a 2-phase circuit of 240 volts can help with more demanding applications such as dryers, washers, and refrigerators.

Unlike residential buildings, commercial buildings are known to consume more power due to the
equipment involved. Typically, commercial electricians use 3-phase power to ensure that the building
gets the needed power without overloading. These are just a few differences between residential and commercial electrical services.
