What is the method to check for line leakage at home?

We must first find the cause of line leakage at home, so that it will be more convenient for you to deal with it, and here is a brief description of what causes line leakage: Wire leakage is mostly caused by wire aging, poor contact, and even moisture. If the wires leak at home, you should find an electrician for rectification in time.

Home is a happy harbor, and to ensure that the whole family lives safely in a special environment, it is necessary to use electricity safely and foolproofly. The leakage of wires at home should first find out what the cause is, and then rectify and solve it in a targeted manner: if it is caused by the aging of the wire, it is necessary to replace the new wire; If it is caused by poor electrical contact, the wire box should be reinserted or replaced; If it is caused by the wrong connection between the neutral wire and the live wire, you need to find an electrician to replace the live wire connector again.

The leakage of electrical wires at home should be investigated in time to eliminate the potential safety hazards of household electricity in time.

First of all, there should be a leakage protector at home, if all electrical appliances are fully turned off, the leakage insurance will trip, indicating that it is a problem with the line, otherwise, it is a leakage of a certain electrical appliance, you can focus on the washing machine, rice cooker, electric frying spoon, electric water heater, etc., you can find it by powering on the experiment piece by piece (it is the leakage insurance tripping when the power is turned on). If it is a problem with the wiring, if you are not an electrician, it is best to find a property to solve it, because it is necessary to use the segmentation method to detect the wiring in the wall to find the fault point.

Turn off all electrical appliances, if the meter is still turning, it means that the line is leaking.

As for where the leakage is, it can be tested with the help of an electric pen.

Measure with an optical gauge, but need to disconnect the load, each circuit should be measured separately, such as measuring a point to the ground resistance is very low, the side indicates that the leakage is serious.

If you touch it with your hands, the place where you can call people will indicate that there is a leakage.

Method 1 First of all, you need to eliminate whether the leakage protection switch itself is faulty, the method is very simple, disconnect the load of the tripped switch, if there is no jump after closing, it means that the switch is good, if it jumps, it means that the switch is broken. If the switch is good, then find another lamp head to connect the wire, install a bulb, one of the wires of the lamp head is connected to the live wire at the output end of the switch, and the other end is the wall (pay attention to safety, this is the method used in the absence of any instrument) If the switch jumps, start the next step, if there is no jump, change the switch (no jump is because there is a problem with the monitoring circuit of the switch, and the load will automatically trip when there is no leakage or short circuit) If it trips, the switch is only connected to the live wire, close the switch, if it jumps, it will follow, Replace it with only connect the zero line, and then connect the test lamp at one end of the switch of each lamp, connect the wall at the other end once, and the light switch at another point once, until the switch manganese copper jumps to the place where the light switch is the leakage or short circuit point. Method 2 maintenance method, disconnect the back wiring of each socket in turn, and electrify the test respectively

1. Disconnect the electric switch, disconnect all the wiring behind the first socket at the farthest point, remember the position, and close the test. 2. If it is not yet closed, disconnect all the wiring behind the second, third and fourth sockets in turn, remember the position, and close the test. 3. If you find a problematic socket, the problem may be that the socket itself is scorched and carbonized, and this socket should not be used 4.

5. If possible, you can use a megohmmeter to cooperate with the inspection 6. Some sockets are equipped with luminous indicators, and related circuit failures can also cause tripping 7. The socket can smell paste in the near place because of scorching and leakage, which is caused by poor plugging of high-power electrical appliances at ordinary times.
