Course venue was good. Plenty to see, and operate. Not sure if it’s something that could be adopted into the course more, but the discipline steps of preforming isolations in the safest ways. Some confusion over if you withdraw ACB’s a lot before withdrawing HV cbs. Also the hazards maybe of cbs failing to close, or CBs struck when racking in or out.. the reality hazards you may come across as an SAP, and how to safely overcome them for new guys training on this course. All good knowledge is worth sharing to ensure people are safe and knowledgable. Content was good and Chris very knowledgable.
