What I think is comical is that the Cutler-Hammer web site makes a big deal bragging about how they support you by continuing to make replacement parts for all their old panels. When you email them asking about XO, then they admit that "all" doesn't include XO.

Around here we use to all keep the old breaker for "Just in case of an emergency" situation. I know we where not suppose to use them, but I wouldn't charge for the part, and I would put on my bill, that it was "ONLY a Temp. fix.". This way in case something went wrong, I at least had a way out of a bad situation. ( Or at least I hoped I did!)
