Electricians can work with a wide range of equipment, from basic electrical accessories to more complex systems. A Certificate III Electrician qualification introduces students to appliances, switchgear, lighting equipment, heating equipment and electrical controls. Learning about different equipment can help students understand how electrical systems are assembled and maintained. AITE’s course includes units covering low-voltage heating equipment, lighting circuits, socket outlet circuits and electrical installations. This variety gives learners exposure to several practical applications. It can also help students understand that electrical work involves much more than installing cables and connecting power points.
