If you let them reset the overload and it trips again you can almost Guarantee that some genious will think, "Hey if I turn it up it probably won,t trip again". Next shift same happens , next shift motor etc burns and then it hits the fan, then you can never find said genius. Theres always a fiddler lurking or someone with just enough training to be dangerous. If its inside a panel there is a good reason for it. It like authourised access only, If you have to ask if your authorised "your not".
