Many breakers will get flipped less than 100 times in their useful lifetime, and will work perfectly throughout their lifetime, so such operation would hardly be "damaging". On the other hand, other breakers may get flipped daily, and having a breaker wear out in in less than a year would not be desirable. | |

Other than whether wear constitutes damage, there is a fair difference in semantics there. | |
