This course is designed to increase the trouble shooting skills and fault diagnostic processes for technicians and maintenance teams on LV equipment. The practical elements of the course Centre on advancing the candidate’s knowledge of diagnosing electrical faults. The course will progressively move toward advancing the candidate’s knowledge of the faults and their rectification on a range of electrical systems.
To gain a detailed understanding of the troubleshooting on LV equipment.
