As long as there is no accident in the electrical box at home, most people will not take the initiative to open it to check!
But do you know that many cases of danger caused by leakage are caused by ignoring the safety of electricity, and this switch in the electrical box must be pressed once a month, not alarmist, and can save life at critical moments!
1. What is this "life-saving switch"?
That's right, it's a "leakage protector"!
Its function is that when there is leakage or short circuit in the circuit at home, the leakage protector will detect the current difference, and then start tripping and power-off, so as to avoid dangerous leakage accidents from the root.
You must know that once the leakage protector fails, if people touch the leaking electrical appliances, there will be a risk of electric shock, which can even threaten life safety.
2. How to ensure that the leakage is normal?
If you have looked at the electrical box at home, you will find that there will be a button on the leakage protector, either orange or white, with "press once a month" written next to it.
And this compression requirement is to ensure that it is normal at all times.
The operation is very simple, press this button, if it trips, and the reset button next to it pops up, it means that the leakage protector is normal.
If the press does not respond and does not trip, it means that there is a problem with the leakage protector, and it is recommended to find a circuit maintenance personnel to check it at home to ensure the safety of electricity at home.
If you want to restore the power supply after pressing, press the button marked "Please press before closing" again, and finally close the switch.
However, it should be noted that before the pressure test, you must remember to turn off the running electrical appliances at home and try to unplug all the plugs to avoid damaging the appliances when the power is off.
Third, for safety, these electrical appliances at home must also be equipped with leakage protection!
Although there is a total leakage protection in the electrical box, these 3 locations in the home, because of the high frequency of use and the high power, it is also recommended to install the leakage protection separately to be safer.
I saw a netizen share before that a neighbor in his community installed an electric water heater, and when an 8-year-old child took a bath, he lost his life due to electricity leakage, and adults had no chance to save it.
Therefore, in the family that installs an electric water heater, leakage protection is a must, it can detect the neutral line, live wire and ground wire, and once the leakage occurs, it can automatically cut off the power supply and eliminate the hidden danger of leakage from the source.
Secondly, when taking a bath with an electric water heater, it must be washed after the power is off, which is safer.
A search on the Internet shows that there are many cases of instant heating faucets burning out, and the safety aspect is really worrying.
The reason for this is that its power is relatively high, many of which are more than 3,000 watts;
The second is that it needs to be heated quickly within a few seconds, and the use environment is still relatively humid, with super heat + humid conditions, which can easily lead to the aging of faucet components, resulting in double the danger.
Moreover, at present, the quality of instant hot faucets is average, the failure rate is high, and there are many miscellaneous brands, which also causes it to have serious safety risks.
If you have a choice, then I recommend using a small kitchen treasure with water storage, there are many big brands, and it is more reliable.
But if you really have to have a tankless water heater, don't forget to install a leakage protector!
For electrical appliances that are temporarily installed at home and are frequently used in a certain period of time, it is also recommended to install leakage protectors as much as possible to ensure safety.

As we all know, the safety of home electricity must still be paid attention to.
