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

    Mar 31, 2020SF 6 is a colourless, odourless, non-toxic gas which is five times denser than air. It has been increasingly deployed in circuit breakers and switchgear in a global array of power stations, wind turbines and electrical sub-stations, to quench arcs and stop short circuits. Often, it replaced oil-filled circuit breakers which contained harmful PCBs.
