One of the useful aspects of a Certificate III Electrician qualification is its broad coverage of electrical applications. Students can learn about systems that may be encountered in residential, commercial and industrial settings. This includes wiring, lighting, socket outlets, appliances, control circuits and electrical equipment. AITE describes UEE30820 as a vocational qualification covering electrical theory, safety, installation, maintenance and repair. The range of subjects gives students an opportunity to understand different types of electrical work rather than concentrating on one narrow application.
