Course Overview

This course provides an understanding of industrial high and low voltage power systems including safe operation on a wide range of power equipment. It enables candidates to perform advanced HV switching operations on industrial HV networks up to and including 15kV. This prepares them for HV authorisation in accordance with their company’s safety rules/regulations. It includes both classroom theory and practical exercises.

Upon completion, candidates will be assessed to a competency level suitable for switching and issuing documents for work on all types of circuit.

Who should attend?

Electrical personnel with a good foundation level of electrical knowledge who are required to carry out advanced HV switching operations and safety document issuing responsibilities up to and including 15kV. The course is aimed at personnel who are to be authorised to multiple grades of duty which company rules may acknowledge as a senior authorised person (SAP). Candidates may find it beneficial to attend our S9 course as a precursor to this course.


Candidates who successfully complete the course and both theoretical and practical assessments will receive a Faraday Centre competence certificate and a certificate of verified achievement issued by EAL. Candidates who fail or do not wish to undertake the competence assessment will receive a Faraday Centre attendance certificate.
