The frequent tripping could indicate an overload which can cause problems with electricity if they are not dealt with promptly. Burning marks on the skin or smell can be indicators of an overheated. If a short circuit occurs or overload is detected the breaker is triggered (opens) and turns off electricity flow that helps prevent the risk of fires as well as other dangers. This may help increase their voltage carrying and interrupting capacity. Visit our website to find the best air circuit breakers.
