Should I replace my GFI outlet with a GFI breaker?
I would replace the GFCI outlet with a new one. The breakers do go bad and would be more of a pain to reset. I have seen gfci's that tripped every time the power cycled replaced and the problem was gone. If you want one that might last a bit longer get a weather resistant one. The electronics are coated so moisture won't affect the circuitry.
