We use circuit breakers everywhere – at our homes, offices, and electric facilities. These instruments are prone to break down as they gather moisture, contaminants, and dirt while in use. Moreover their insulation can also become weak because of the heat that is created due to arc interruption if it is not maintained regularly. Chemicals like hydrogen sulphide or chlorine can be major factors in the damage and corrosion of insulation as well as metal components of circuit breakers.
