Electricity, as an indispensable energy source in our daily life, maintains the normal operation of various electrical appliances in the home. While we decorate the buried circuit, we will also set up a power main switch in the home to control the power supply of the whole family. However, many times, this master switch silently assumes its responsibilities on weekdays, and we tend to ignore its existence, unless we encounter a power outage at home, we will remember to check this master switch. But did you know that a button in the electrical box at home needs to be pressed once a month, but many friends ignore it. So which button is it? Let's find out with me!
This button is actually a leakage protector, and its main function is to prevent electric shock accidents caused by leakage of electrical equipment. When there is leakage of electrical equipment, the leakage protection switch can cut off the power supply in a very short time, so as to avoid the current from passing through the human body and ensure our life safety. Maybe many friends don't notice that there is a small button next to the leakage protector, and next to this small button is marked: "Press once a month".
So, why do we have to press this switch once a month? Maybe many friends have never pressed this switch since the renovation and moving in, but in fact, it is very necessary to press this switch once a month, because the leakage protector may fail or fail in the process of long-term work. If the test is not carried out for a long time, once there is a real leakage, the power supply may not be cut off in time, which will cause an electric shock accident. Therefore, pressing the leakage protection switch once a month is to simulate a leakage event and check whether the switch can work normally.
If we press this small button, the leakage protector next to it can immediately trip automatically, then it means that the leakage protector is normal, and it can automatically cut off the power when there is a sudden leakage situation at home to protect our safety. But if we press this small button, the leakage protector can not trip automatically, it means that it has a fault, and it is very dangerous at this time. Once a leakage short circuit is found in the home, the leakage protector cannot automatically power off, and it may also bring serious consequences. Therefore, this small button next to the leakage protector is very necessary for us to press once a month. If you find that the leakage protector is out of order, you should pay attention to it immediately, find a special electrician to repair it, or replace it with a new leakage protector. Electricity safety is very important, it is related to our personal and property safety, we should be careful, and press this button will not waste much of our time.
