Course Overview

This course is a refresher programme designed for personnel who have limited high voltage authorisation restricted to switching operations and issuing documents for work on single end drive circuits only. It includes both classroom theory and practical exercises. Upon completion, candidates will be assessed to a competency level suitable for an authorised person (AP) switching and issuing documents for work on single end circuits only.

Who should attend?
