Electrical machines are used in many commercial and industrial environments. A Certificate III Electrician course can provide students with an introduction to equipment such as DC machines and AC rotating machines. Learners can develop knowledge about electrical principles and how machines are tested and connected. AITE includes units covering problems in DC machines and testing and connecting AC rotating machines. This gives students exposure to electrical applications that go beyond standard household installations. Understanding machines can also help learners build a broader technical foundation as they progress through their electrical studies and consider different areas of the industry.
