Precautions to Prevent Overheating of the Electrical Connector
1 When the fault occurs, the power cord electrical connector should be disconnected and the conductive column inside the electric water heater socket should be unscrewed. Use a zero-size abrasive cloth or abrasive paste to polish it. Remove the wires from the power cord and the electrical connector. The wiring layer, the tongue and the oxide layer of the conductive column in the socket on the electric water heater reduce the contact resistance.
2 Apply a little conductive paste to the power cord connector and the socket lead of the electric water heater.
3 The tongue and the terminal screw on the electrical connector are severely damaged and need to be replaced immediately.
4 The socket and the conductive column on the electric water heater should be removed immediately, and the socket and the conductive column of the same specification should be replaced. When installing an electric water heater socket, a power knife switch should be installed.
