Well if they were to replace all the FPE breakers with the new ones (available only in Canada for what I know), then the panels would become reliable again. As far as I understand, they have completely fixed the FPE breakers as of 1997. The new ones that either have a small hole in the handle, or have a flat handle, are perfectly reliable.
95% of new houses built here get those panels, including my parent's house, and they do trip properly.
My uncle's house I am a little worried about though, as it has 1996 model FPE breakers without the small hole in the handles.
But I seriously wonder why the US doesn't just allow them to be replaced with the new ones. They are being made and any testing laboratory and agency could verify that the new ones actually work. They have the same bus connectors and so they would fit compatibly.
