U/L was throwing Cuttler Hammer a bone when they "classified" Challenger breakers for Square D panels.
We used to have a CH rep and a U/L rep in our IAEI chapter and they was good friends with Jim Pauley from SqD who used to do seminars all the time. We were guaranteed to hear the whole classified breaker story every time Jim was in town.

Personally I never saw it as being a big deal. If U/L evaluated the breaker in that panel, I believe them, no matter what SqD says.

I always saw the U/L label as being about like Conagra telling me Hebrew National hot dogs should be served on Peppridge Farm bread with Guldens mustard.
