 Gabaɗaya Jagora When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have  been overheated or damaged by the short circuit.  After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.  After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
