just recently looking at old threads on tandems and saw the tandem breaker that i have and wondered if you could install it in a 42 space panel, i know there are two types of tandems and one has what appears to be a rejection hook, i've been looking in the book and can't seem to find if i can install one of these breakers in a 42 space panel. Can anyone give me some feed back on this? it seems to fit but a little loose on the hook side thanks.
