A certified electrical contractor’s skill is needed for electrical wiring in both residential and commercial premises, since it may be a complicated operation. This is crucial because it assures compliance to the Electrical Safety Authority’s (ESA) electrical regulations and safeguards the security of the building and all of its occupants. For a skilled electrician, electrical wiring may often be simple; but, wiring a commercial building might be significantly more complex than wiring a home. Electrical wiring is set up in commercial buildings to support any machinery or heavy equipment that will be operated there.
The three main methods for electrical wiring in commercial buildings are raceways and conductors, busways and cable assemblies.
Raceways and Conductors
Raceways and conductors are among the most typical forms of commercial electrical wiring. Raceways and conductors are frequently used in conjunction with a conduit or tube that contains numerous insulated phases as well as a conductor for equipment grounding. The actual design and installation will differ, as with other forms of electrical wiring, depending on the requirements and specifications of the business property. Copper/aluminum THHN/THWN or XHHW conductors are the most prevalent variety, just like cable assemblies. Branch circuits are often made of copper, whereas feeders are typically made of aluminium.
An advantage of raceways and conductors is that it allows for changes in circuit configuration, and raceways can be easily used for remodelling projects. On the other hand, some disadvantages are higher installation costs compared to other wiring methods, and a complex installation process due to more rigid routing requirements.
Another approach that is frequently employed in electrical wiring is the cable assembly method. Multiple insulated and neutral phase conductors are combined with an insulated and/or bare equipment grounding conductor to form cable assemblies. Custom cable configurations are available and typically use copper or aluminium conductors that are THHN/THWN (thermoplastic high heat-resistant nylon jacket/thermoplastic high heat-resistant and water-resistant nylon jacket) or XHHW-2 (XLPE high heat-resistant and water-resistant conductors).
Compared to the other wiring methods, a few advantages of using cable assemblies is a quick installation time and lower installation cost, in addition to cable routing flexibility. On the other hand, a disadvantage is that changes in circuit configuration are not possible once installation is complete, and that more planning is required during the configuration and cable procurement stages.
A busway is an enclosed raceway with factory-mounted busbars. Busways typically come in two different configurations: plug-in style and feeder style. They can be used with bare or insulated conductors. The busway technology is useful because it can handle ampere ratings ranging from 60 to 4,000 A and is more compact and lower in size than several conduits. Additionally, with busways, the overall voltage loss has less of an effect. Busways have a greater cost of installation than other alternatives, and they are more susceptible to collapse as a consequence of internal water leakage. Additionally, there may not be sufficient space to accommodate bus plugs depending on how the area is structured out.
