Low-voltage systems form an important part of everyday electrical work. A Certificate III in Electrotechnology Electrician covers several areas involving low-voltage circuits, including wiring, lighting, socket outlets, appliances and electrical controls. Students also learn how to isolate, test and troubleshoot low-voltage electrical circuits. This combination of installation and testing knowledge can help learners understand how electrical systems should be approached safely. AITE’s course structure includes multiple units dedicated to low-voltage electrical work, providing students with exposure to different applications and technical requirements.
