Hi, I have an old GE main breaker that needs to be replaced. Wondering if anyone knows if the newer ge breaker will work with this tie down kit? It seems like the newer ge breaker has a much smaller clamp point or whatever you wanna call it. Here's some pics too.
Thanks

Not a expert on GE components, but here is what mains have looked like for 25 years or so:

I'd guess as long as the breaker has the notch like shown in your second image it probably will work with the older hold down hardware.

I could possibly see only a 22kAic rated breaker possibly having that notch as that is what would be commonly used for main breakers in these.

I don't know what direction ABB is going with this product line, but for now I think it still exists.
 
Yes, but my concern is that notch on the new breakers is much smaller. That old one goes deep into the breaker whereas the new one just has maybe an 1/8th in ledge
