I have recently been dealing with a hypersensitive windless breaker. If I retrieve after paying out too quickly, it trips. Sometimes there is mud on the anchor and I drop it back in to wash off the mud, then retrieve it. I see how this can overload the circuit, but its not like I'm quickly reversing while its on full-speed in the opposite direction. It seems the episodes are becoming more frequent and the breaker more sensitive. It even happens with no load, reversing with a slack chain. I don't think it ever happened while retrieving, even under load. I try to idle up to the anchor when retrieving anyway. It is possible the breaker is getting weak? What a PITA, because the breaker is inside a waterproof panel with 4 Phillips head screws holding it shut. The worst part is that it could potentially cause a grounding if the breaker trips when the anchor is not holding on the bottom or dangling 10 feet under the boat. One time I had to retrieve with the hand crank, because I had no time to mess with opening the panel in a windy, tight anchorage.
