Also the hom breaker to bus connection is patterned after the old westinghouse standard and is considered less reliable than the qo breaker to bus connection which is unique to qo.

I have installled the homeline series for about 6 years and have had no call backs on them.

The internal workings are the same. Well over the years here i have read several times that the internals on square d homeline and qo breakers were the same the only difference being the breaker width and the qo having invisi trip.
