Abstract Aimed at the existing problems in classification and application of equipotential bonding，started from the three basic elements of equipotential bonding， the PE conductor （including equipotential bonding terminal），external conductive parts and exposed conductive parts，the safety and the importance of equipotential bonding are systematically analyzed. On this basis，the classification of equipotential bonding is refined and the suggestions to improve the application of equipotential bonding are given.
