Let's keep in mind that it was never intended for the code writers and listing agencies to do all our thinking for us.
Counterfeiting aside, I've seen all manner of listed kludge that I wouldn't use for balloon ballast. I've also seen otherwise sane folks get their hackles up when they see a rock-solid 'custom' enclosure, or lose sleep when they have to fabricate a replacement part for an older installation.
If someone can counterfeit a breaker, making a fake UL sticker is a piece of cake. Heck, I have an entire roll of REAL lables that turned up at a flea market. Need I say more?
So buyer .. be aware.
