What are the safety problems that electric water heaters have in use?
Three, in the use of electric water heater, not through the plug on the switch off the power supply, because the power supply after the switch off the plug, leakage protection plug can not work, once the ground wire, such as electricity failure, can not provide protection.Four, regular (general weekly) check the leakage test plug to ensure that the leakage protection plug can work properly.Five, maintenance, cleaning, electric water heater outside, should first cut off the power supply, do not spray with water, soft cloth to wipe.
First, the indoor wiring of the house should be reliably grounded, and the grounding resistance shall not exceed 4 ohms. The home socket, regardless of the single-phase or three-phase power supply, must be grounded with the ground wire of the power source, and the grounding electrode of the socket is not allowed to be empty.Two, electric water heater equipped with sockets, should be with the ground wire fixed special socket, can not use mobile power wiring board. The structure, capacity and Jack size of the socket shall be matched with the power plug of the electric water heater. The outlet shall be placed above the level of the outlet of the electric water heater. Avoid the danger of short circuit caused by water splashing.
Compared to other electric water heaters, water heaters are safe, but it is recommended to buy some brands, which are 3C certified. Such as Smith, Haier, Yang Zi, Vanward, MeiLing, and Macro to Yameina electric water heater, he has 2 sets of security system. The first is the PS security system, which was first adopted by Smith, but now the general brand has been adopted. Second is the three line disconnection protection system, once the leakage of electric shock occurs, his FireWire, ground, zero line will be disconnected at the same time, the loss will be reduced to the minimum, basically there is no possibility of electric shock. As long as the use of attention, the following points will not be the problem.
