Electricians scope of work may change depending on their specialisation and expertise. In Australia, there are numerous specialisations that a person can choose. But the three most common are the residential electrician, commercial electrician, and data cabling electrician.
The residential and commercial electricians’ responsibilities are the same – planning, installation, maintenance, and repair. Their only difference is environment settings, the power needed, materials used and installation method. Since residential housing has a maximum of two floors, unlike in commercial buildings, the load of power needed is much lesser. For this requirement, electricians use a single-phase power for residential; while in commercial buildings is a three-phase design.
In terms of materials used, electricians use narrow and fine wiring encased in a plastic sheathing for residential housing. While for commercial buildings, Electricians use heavy duty wirings to ensure it can handle the higher power demand. The wirings are commonly enclosed in a tube-shaped casing for added protection.
Lastly, for the installation method, both residential and commercial electricians aim for accessibility. For residential housing, electricians install the wirings before the drywall and the control systems in any open space (e.g. basement or attic). While for the commercial buildings, the wirings are installed inside a ducting system.
The other known specialisation of electricians is the data cabling. As smart devices continue to grow its popularity, the demand for data cabling electrician grows as well. Few of the responsibilities of data cabling electricians are the following:
- Connect all the wires of the computers and other smart equipment together for them to easily communicate with each other.
- Design a clear layout on where to install phone sockets, fire alarm systems, CCTV cameras, and more.
- Installation, repair and maintenance tasks
