If you want to be proactive, swap out any circuit breaker that trips repeatedly or that feels spongy when switched manually. (A breaker''s lever should snap into place when flipped.) That''s why the long-standing recommendation to manually trip and reset each breaker a couple of times a year is still worth following."
