Installation is a major part of electrical work, and students undertaking a Certificate III in Electrotechnology Electrician learn about installing low-voltage wiring, appliances, switchgear and associated accessories. Training can help learners understand how electrical components are selected, positioned and connected as part of an installation. Students also study wiring systems and cable selection for low-voltage electrical installations. These skills are relevant to many electrical work environments, including residential and commercial settings. Understanding installation requirements also helps learners appreciate why correct planning, testing and compliance are important when working with electrical equipment and fixed electrical systems.
