CharlieE,
that's what actually got this thread started for me. the facility I work at now swapped out a bunch of panels in 2 of our buildings a few years ago, and within the last year, about 40 two-pole breakers "froze up" in the off/tripped position. Upon replacement of said breakers, it was discovered that they were of the HACR type. I had a hunch that they wore out due to misapplication. (they were feeding lights and outlets.) either that, or they just got a bad batch off the production line?
