How to check if there is leakage in the wires at home, and how to check the leakage of the wires at

Maintenance method, disconnect the back wiring of 6 sockets in turn, and test them separately

1. Disconnect the electric switch, disconnect all the wiring behind the farthest first socket, remember the position, and close the test.

2. If it can't be closed, disconnect all the wiring behind the second, third and fourth sockets in turn.

Accurate position, closing test.

3. If you find a problematic socket, the problem may be that the socket itself is charred and carbonized, so don't use this socket.

4. There may also be related circuit problems on the wall, and the multimeter has a high resistance level to detect the insulation between the lines and the insulation to the ground.

5. If conditions permit, you can use a megohmmeter to cooperate with the inspection.

6. Some sockets are equipped with light-emitting indicators, and related circuit failures can also cause tripping.

7. The socket can smell the paste smell in the near place because of the scorching and leakage, which is caused by the poor plugging of high-power electrical appliances.

How to find which wire is leaking at home? In fact, the method is very simple, and you will learn it as soon as you learn it.

There is a leakage at home, how to troubleshoot the leakage fault? The old electrician teaches you hands-on, practical electrician techniques!

Your home is a total trip of missing insurance; Don't use it, buy a circuit breaker and install it. If the circuit breaker trips due to leakage, unplug all electrical appliances, turn off the light switches, and check them one by one.

First, use the 10k resistance file of the multimeter to test the six socket holes connected by the problematic small gate, and find which socket has a resistance value (the meter hand waves), indicating that the socket has a short circuit fault between wires. Then for troubleshooting.

The leakage protection switch can not detect the short-circuit fault, the small switch below is the air switch, it may be that a socket is short-circuited, disassemble the socket and check it.

Each empty pipe is opened all the way, so that you are sure which route it is, and then use a multimeter to measure the circuit to know that there is a problem.

All six sockets are turned on and tried next to each other.

You can only check socket by outlet to see if there is a short circuit.

Electrical circuits come due to the service life is relatively large.

The source is long, which will cause the insulation to become old, the insulator to be damaged, and the insulation layer to be damp or abrasive

Hello, line leakage may be caused by aging lines, broken insulation, equipment failure, etc. To find out the leakage, you can follow the steps below:1

Power outage: First of all, you need to disconnect the power supply to ensure safety. 2.

Check the line: check whether the line is aging, insulation damage, equipment failure, etc. 3.

Use a pen or multimeter: In the power-off state, use a pen or multimeter to test the voltage on the line to determine if the circuit is leaking. 4.

Check the cause of leakage: If the circuit leakage is found, it is necessary to further investigate the cause of leakage, such as whether there is a grounding fault, equipment damage, etc. 5.

Repair leakage: Repair according to the cause of leakage, such as replacing aging lines, repairing damaged insulation, replacing damaged equipment, etc. It should be noted that when investigating the leakage problem, we must pay attention to safety to avoid the occurrence of electric shock accidents.

In daily life, in order to avoid safety accidents caused by line leakage, you can regularly check the home circuit, such as replacing aging wires, installing leakage protectors, etc., to ensure the safety of household electricity.

This looks at the switch that controls those electrical appliances, and then unplugs all the controlled electrical appliances, close the switch to see if it jumps? Do not jump in one plug at a time. Jumped, the power was stopped, dialed to the resistance gear with a multimeter, and measured the resistance of the live wire and the neutral wire to the ground, if the resistance of the live wire, the neutral line to the ground was a few ohms or tens of hundreds of ohms (to make sure that the electrical appliances under the switch were disconnected), then there was only a bright wire, find a professional electrician.

Wire leakage has not been checked, thanks to the old electrician taught me, it turns out that leakage can also be checked in this way.
