The Difference Between Commercial and Residential Electrical Installation: An Expert's Perspective

When it comes to electrical installation, there are distinct differences between commercial and residential properties.

Residential electricians

typically work with high-voltage systems between 120 and 240 volts that supply electrical power to homes, while commercial electricians can work with very high voltage systems exceeding 240 volts in large commercial buildings. The way electrical wiring is placed is not the only difference. In residential properties, the cables are thin and narrow, making it easy to place them in the plastic lining.

In a commercial property, the wiring is thicker and wider, so it is contained in tube-shaped ducts or even in the ceiling beams for protection and ease of access. This is important because commercial locations change more frequently than residential locations, so wiring must be placed in easily accessible areas for maintenance. Naturally, commercial structures have a higher demand for electrical load, unique energy needs and a completely different configuration than residential structures. The first and most notable difference between residential and commercial wiring is the material itself.

In a house, where the wiring is usually placed in an attic or mezzanine, it is important that the cable is covered with a plastic sheath, usually made of PVC. The requirements for commercial wiring are very different from the requirements for residential wiring. Both residential and commercial electricians begin their education and training in the same place. They work with what is known as a three-phase design that allows them to work together to meet the high demand of a commercial occupant.

The single-phase system of a residential property is powerful enough to power a house and provide electricity to meet the needs of a household. Wiring is like your building's blood supply, and if your commercial building doesn't have it properly installed, you risk running out of electricity or even starting a fire. Many electricians make exceptions for large residential projects such as large houses and estates or apartment buildings which may have systems as complicated as those of a commercial project. These include safety regulations for electrical equipment, personal safety standards to which they adhere, and the level of insurance against possible disasters caused by electrical faults.

The right electrical upgrade can significantly improve the value and appearance of any home or business. Commercial electrical contractors require more expertise due to factors of complexity, safety, and reliability. This phased design system helps distribute electrical charge so it doesn't hit a cable all at once. If you want a commercial property to have the best chance of using energy properly, you must ensure that you use the right wiring for the job.

The flow of electricity is controlled by the electrical panel, ensuring that the entire system is not overloaded but also that it is sufficiently supplied. A notable difference between the configuration of a commercial building and that of a house apart from the configuration of electrical wiring is the importance attached to aesthetics. Commercial systems tend to fail more frequently and require more maintenance so most are installed in easily accessible locations with access panels for troubleshooting.
