• S10 – 33kV Upgrade Course (indoor equipment)

      This course is designed for personnel who have previous authorisation up to 15kV and wish to extend their authorisation level to enable them to operate on (indoor) 33kV systems. The course focuses on the practical element of switching and is predominantly workshop rather than classroom based. This course should be undertaken as an augmentation to the S4 (or similar) full authorisation course.
