The notches are for twin breakers, I believe. I didn't use twins very often so I don't remember. I also think the older GE breakers may not fit in the newer panels. At one time GE and ITE were almost totally compatible but that changed many years ago.Trying to jog my brain here.
I remember something about bus stabs, the notch where the breaker goes onto the bus, and incompatibility with the two for certain panels.....cannot remember....
To be honest, I haven't been in the field that often in the past 9 years so I am not certain of anything anymore. LOL
