I became an insp in 2002-so I haven't done this in at least 7 years-bless me father-its been 7 years since my last confession--The short answer is that was why I had my extra pair of "Blow out Pliers"[they were the ones that had that hole blown out in them so long ago].
There was nothing better than tryinf to short out an FP brkr though.Don't want to try that around a nice white wall and not without full arc protection gear on if you know what I'm sayin'!.
ps-this was a last resort method only employed in my early years--the loud radio method mentione d by Mr Fine was a much better way.but I still have those blow out pliers so I don't forget.
