[QUOTE="roys, post: 493635, member: 5044"] The last one I had similar to that was an ACB bus tie breaker on a 660V board. Pressed trip with the remote key switches, failed to trip, stood to the side of it and pressed the manual trip, still no trip, oh oh. Got all the loads removed, then tripped the incomers. Defeated the door interlock, then my mate and I set about it with our big screwdrivers being very aware of the spring mechanisms, eventually it tripped with a very load mechanical bang, both of us looked at each other wondering if each other still had all ten fingers. Definentley one of my more check clenching moments. [/QUOTE]
