At present, many households still use electric water heaters. Installation of electric water heaters can not avoid doing a good job of safety, in fact, do you know? The safety of electric water heater has a great relationship with socket. Today Xiaobian will tell you about the plug of electric water heater.
Family indoor wiring should be reliable grounding, and grounding resistance should not be greater than 4_. The grounding of household sockets, whether single-phase or three-phase, must be connected to the ground of the power supply. The grounding pole of the socket should not be empty.
Electric water heaters should be equipped with fixed special sockets with ground wires. Mobile power supply wiring boards should not be used. The structure, capacity and size of the socket should match the power plug of the electric water heater. The socket should be placed above the horizontal position of the outlet of the electric water heater to avoid the danger of short circuit caused by water splashing.
When using the electric water heater, the power supply should not be turned off by the switch on the socket, because the leakage protection plug can not work after the power supply of the socket is turned off, and it can not provide protection once the ground wire is live and other faults occur. If the power cord is damaged, in order to avoid danger, special power cord provided by the manufacturer must be used and replaced by professionals from the Maintenance Department or similar departments.
In addition, many people use electric water heaters to save electricity, switch on and off, and do not use water heaters for a long time. In order to save energy, they can cut off the power supply. As long as the water heater is qualified by the national inspection, it is not harmful to turn on the power switch for one or two days. If it is not used for more than three days, or even for several consecutive months, it is better to cut off the power supply and pull out the plug. If hot water is frequently used, it can be left on all the time, but the best time to start two times is a long interval, otherwise it will not only consume electricity but also damage the machine.
Real energy-saving electric water heaters do not need to cut off power frequently, because their insulation function needs to be completed under the power on. Frequent power outages will cause these energy-saving functions to fail to start, coupled with frequent unplugging of plugs, which will reduce plug life, and even bring unnecessary security risks.
