DQDICK, you did mean two same rated breakers in parallel, not in sequence (serial). Either get a single 80amp or 100 amp, or dual 40amp or dual 50 amp in parallel. Electrically speaking, dual rated breakers are additive, but they must be the same rating and age. I don't believe it's a good idea to mix breakers. When I did my fix, I bought two brand new 40 amps, installed them in parallel and voila, slideout stuttering was fixed. Learned all about it in the MOC.
