I know that we had this discussion before about different breakers going into different panels. I saw a job where a GE breaker was in a Challenger panel. I know that Cutler Hammer bought out Challenger and I know that Bryant was also bought out. So the black square breakers are UL listed for Bryant, Challenger and Cutler Hammer. I was tying to find a website to see if GE is listed for the Challenger panel. Is it? Or is there a website I can look it up?
