I was at a garage sale today, they had a box of a dozen or so triple
60 amp breakers. I didn't check what brand, or type of panel.
The guy wanted two bucks each. Looked new.
I've not used a triple breaker in ages (and then only once). Anyone want em? Give me a shout, and we'll work out the money, postage, and all that. Sale is June 7,8,9. Git im while they're hot.
Or I can go back and ask for details. Brand, etc.
