Electrical installations: fault diagnosis and rectification

Aim: The unit is designed to enable learners to understand how to carry out fault diagnosis and rectification of complex electrical systems safely and in accordance with regulatory requirements, with an emphasis on period inspection scenarios. Learners will also develop the skills to apply their understanding of fault diagnosis in simulated environments.
