I know it's out of date, but what if one burnt up in a panel, it would be worth lot more. But again if it was me needing it, I would be glad to pay $12.50 for it smile Just depends on whether you're trying to buy or sell smile Thanks again for the help....


The Q1 breaker family was obsoleted some 30years ago.
An equivalent rated QO breaker is a 100% adequate replacement (except for the 'top feed' main breaker version - Q12100TF).
