    I was told by my instructor after every break they become weaker and will break under a lower amperage. He also said after 3 trips they should be replaced and same goes for surge protectors.

    I had a furnace that I couldn't find the breaker for. So I grounded it out. 20 amp breaker. Tripped the main... Oooops!

    I had rep. for a electrical company tell me that breakers are only guaranteed for one trip, they may work after that but are only guaranteed for one trip.

    So if you buy a "new" or different home first thing you should do is change the breakers cause you don't know how many times they have been tripped? Can honestly say I have never seen anyone do anything like that, and I would think if breakers had such a short life span that would be common practice. I would have to agree that I would think direct shorts cannot be good for breakers but not sure how they could put a number on it. If they were that susceptible to damage you would think they would make them inoperable after a dead short. In fact I'm surprised they haven't being that they could sell a lot more breakers and take more liability of themselves (the manufacturers) that is. If we just go back to glass screw in fuses we will all be safe

    I do that kind of stuff when I am thinking! Changing a contactor two weeks ago while talking to my help and felt my pinky go into hyper drive....forgot to turn off the disconnect.

    I have replaced many breakers because they had gone soft from being tripped repeatedly. I have also replaced breakers because they were Federal Pacific. That's about the same thing as not opening when they are supposed to.

    breakers do get weak but no they are not rated for one trip only. One trip only is called a fuse. When breakers came into being the old sparkies started the one trip only fantasy to sell stuff or just out of ignorance and its still with us all these years later.

When he told me this story all I could do was to laph, he got a little upset I told him well that's the last time you trust someone else to kill the juice. I also told him the volt meter in his bag is a good thing to use too. After seeing pictures I don't understand how the heck he got the disconnect taken apart without getting hit.
