Industrial environments use a wide range of electrical equipment, control systems and machinery. A Certificate III in Electrotechnology Electrician includes units that introduce learners to electrical machines, transformers, rotating equipment and control circuits. Students can also study direct-current machines and magnetic and electromagnetic devices. This provides an opportunity to understand electrical principles that may be encountered in industrial settings. While individual job responsibilities can vary, having a broad understanding of electrical systems can help learners adapt to different work environments. The course therefore provides exposure to electrical concepts beyond basic household wiring and installations.
