Safety should always come first in all electrical tasks, including wiring. For both commercial and residential structures, electrical wiring may be a challenging task. It is best left to the expertise and experience of a certified electrical contractor to carry out the job securely and in compliance with the Electrical Safety Authority’s (ESA) electrical code. Although completing electrical work in residential and commercial spaces is similar, wiring in commercial spaces takes extra caution since the wiring must be set up to account for any heavy tools and machinery present in the space.
The three main methods used for electrical wiring in commercial facilities are cable assemblies, raceways and conductors, and busways.
The use of a cable assembly is extremely common when it comes to electrical wiring in a commercial setting. Many insulated and neutral phase conductors can be found in the cable assemblies’ equipment grounding wire. Custom cable assemblies are available and commonly include copper or aluminium conductors that are either THHN/THWN (thermoplastic high heat-resistant nylon jacket) or XHHW-2 (XLPE high heat-resistant and water-resistant nylon jacket).
In comparison to traditional wiring methods, using cable assemblies provides a few advantages, such as flexible cable routing, lower installation costs, and speedier installation timeframes. The consequence of being unable to change the circuit configuration after it has been installed is that it requires more planning before installation.
Raceways and Conductors
The raceway and conductor approach is another widely employed strategy. When employing raceways and conductors, a tube or conduit with an equipment grounding conductor and several insulated phases is often used. As with any type of electrical project, the actual design and installation will vary depending on the demands and requirements of the commercial property. Copper/aluminum conductor types THHN/THWN or XHHW are the most often used conductor kinds, similar to cable assemblies. Typically, branch circuits are built of copper while feeders are made of aluminium.
Raceways and conductors have the advantage of permitting modifications in circuit arrangement in comparison to the cable assembly method, and raceways are easy to use for remodelling projects. However, some disadvantages include higher installation costs in contrast to other wiring systems and a difficult installation process due to stringent routing requirements.
The third most common method for commercial wiring is a busway, which is an enclosed raceway with busbars. In most cases, busways are plug-in or feeder designs that can handle insulated or bare wires. The busway method has a number of benefits, including the fact that it is smaller and more compact than many conduits and is available in ampere levels ranging from 60 to 4,000 A. Furthermore, the total voltage loss is less of an issue with busways. Conversely, the busway technique has a few disadvantages, such as a higher installation cost and a propensity for busways to collapse if there are any water leaks inside the building. Moreover, there might not be enough space.
Despite the fact that these three commercial wiring methods are the most common, there may be more possibilities.
