breakers trip from heat, my theory is contacts degrade a little, heat

Ah, so it's another hallerb "theory". We can safely ignore it in that
case.

no i report what westinghouse breaker design engineers told me........

they would change with age so they were made more sensitive to trip on
less current than designed........

this was better than starting a fire..

i happened to be there one day when they were testing knock off
westinghouse breakers, made in mexico. looked just like the ones they
produced from the outside.

when taken to 120% of rated current they exploded, a real fireball.
these breakers were high voltage distribution ones

so has anyone found a breaker that wouldnt trip other than FPE stab
lock??

I've seen breakers of all manufacturers fail. You think Federal is the only
brand that's had that problem. Try Frank Adams or Zinsco. Personally I think
the only difference is that Federal sold more product
