Electrical Technician FAQs

While electricians and electrical technicians both deal with electrical systems, the nature of their work is different. Electricians install, maintain, troubleshoot, and repair the wiring in buildings, whether that be residential homes, offices, or commercial properties. On the other hand, electrical technicians work on electrical systems within machinery, specialty equipment, and other commonly used devices.

Electrical technicians help maintain and repair electronic components in any equipment or device that uses electricity. Their work can vary from helping with product design to working on site to keep machinery and power systems running correctly.

Yes. As with any technology, electrical work evolves and electrical technicians need to understand emerging automation, such as programmable logic controllers (PLC) and network communication, robot-controlled equipment, and the Internet of Things (IoT).
