Okay, I'll be the bad guy. I don't write it up, even though there's no question that it violates the manufacturers' specs and instructions. In an accumulated 20 years or so of selling the stuff, tinkering and doing wiring, and inspecting I have yet to see one single instance where it caused any problem at all. After all this time, I ain't writing it up until I see one. I don't fault anyone else for doing otherwise, I'm just totally convinced this is a meaningless issue. I've heard that some manufacturers are beginning to pay the extra money to have thier breakers tested (and therefore listed) to go in other brands of panel with like designs, but I can't confirm that at the moment. They may as well, 'cause there's isn't 2 cents difference in any of them on the inside (residential stuff). Around here I rarely see a house more than 5 years old that doesn't have at least one odd breaker in it. Brian G. Wild Insane HI, Skating on the Ragged Edge of Disaster [:-masked]
