Just another reason for someone to invent a means to actually TEST breakers in the field.
Let's face it; we have no idea what's inside any breaker, or whether it will operate when needed. We have no way to determine that an older breaker has been damaged over time. We must simply take it all on faith.
Today it's breakers; not so long ago, it was fake GFCI's ... pushing the 'test' button simply shut the thing off. Some 'test!'
Add bogus AFCI breakers to the equation, and the field is ripe for a rash of fake products.
If Square D's reaction to AFCI "testers" is any indication, they will strongly oppose the development of ANY test equipment that isn't made by them.
Greg, the problem there is... what if your test fails? There's really no good safe way for a field test short of an actual breaker tester. Which is required when calibrating some of the more sophisticated breakers, but I can't see it happening for anything short of a 1200A ACB.
Ya know, honestly, the LEAST they could have done was used #18 wire for the jumper so it would act as a fuse! Would have saved them even more money, too, and maybe keep them tied up in litigation vice a homicide trial if/when they get caught.
