ELECTRIC WATER HEATER ELECTRIC LEAKAGE DETECTION METHOD AND ELECTRIC WATER HEATER

摘要

An electric water heater electric leakage detection method, the method comprising: when a dual optical coupling electric leakage detection component (2) detects the occurrence of an electric leakage signal in at least one of the following two positions, a control apparatus (12) cuts off the power source of the electric water heater on the basis of the electric leakage signal, the two positions comprising a position between a live wire (13) and a ground wire (14) and a position between a null wire (15) and the ground wire (14).
