With a recent factory upgrade, I had the
un-enviable task of throwing the Main Isolator, back into service, and got the handle stuck half way, I heard and saw welding of the contacts inside the Isolator
(1000A@400V).
How would you go about opening or closing a
High current Isolator, have I got it all wrong?.
