Thanks John. I had looked on the breaker before, but your post got me checking first a Square D "Digest" catalog I had, then it "sparked"

my mind to look on the breaker again. On the side of the breaker there was a piece of paper that was almost torn off, but I pieced it back together and came up with QI390, pulled it up on the web, got a hit for ebay; went to ebay and they got one on there for $ 12.50

Can't believe someone selling that cheap. I know it's out of date, but what if one burnt up in a panel, it would be worth lot more.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

Just depends on whether you're trying to buy or sell

Thanks again for the help....
