    Nov 16, 2011When racking a MV breaker in or out, get it done. Dont stop in the middle. Never force a SF-6 breaker open when the gas pressure is low. To do so will almost always result in an explosion. There is a reason why the electrical controls will lock it out on low gas pressure. Thats all I can think of off the top of my head. Rob
