It was good to work on different switchgear in the practical area, different switching procedures for the switching schedule was useful and I will take it into my schedule for the future, overall Gary was very knowledgeable and approachable for when I wasn’t sure on a procedure , really enjoyed the course

Very good and detailed course with huge array of different switchgear. Covered good points and good protection exercise. Slightly more in depth protection would of been good also but overall great course

Very good course with plenty of field experience examples brought by Lee to reinforce course content. Brilliant variety of switchgear. Workshop was a bit cool on first day where there was more observation and less participation (extra layer of clothing on subsequent days helped!).
