The wires at home are short circuited, how to find the short circuited wires?

1. First disconnect all appliances on the socket and turn off the air switch. If the handover is successful, the circuit is normal; If the connection is not successful, double-check that any power supply is not being pulled down. If it is confirmed that there is no electrical line, it is a line fault. Have a professional electrician repair it.

2.The fire wire is short-circuited with the protection wire. Disconnect the main switch, disconnect the protective wire of the household, and measure whether there is no connection between the live wire and the protective wire of each socket with an electric meter r*100. If so, it proves that the live wire and the protection wire are short-circuited. Turn on each outlet and look for them one by one.

3.Turn on all the lighting fixtures one by one, which trips, indicating that the lighting fixtures are short-circuited.

4.Turn on all the lighting fixtures, then plug in the unplugged appliances one by one and turn them on. Which tripped, it means that it was short-circuited by the electrical appliance, 5Turn on your master switch again and see if it trips (first check if your fuse burns out).

6.If you jump, it's a short circuit in the main line. Then you can see if there is a short circuit in the joints of the main line or some turning places, as well as the plug at home, which is also easy to short circuit.

1。First disconnect the electrical appliances on all sockets, close the air switch, if the closing is successful, it means that the circuit is normal; If the closing is unsuccessful, carefully check whether there is an electrical power supply that has not been torn off, and confirm that there is no electrical appliance**, it is a line failure, and a professional electrician should be asked to repair it.

2。Load the appliances one by one, and the one that trips is the faulty appliance.

3。Loading all electrical appliances does not trip, it is an occasional failure, statistics of the total power of electrical appliances, whether the empty current is too small? Yes, just change the empty space; No, use it with caution, and ask a professional electrician to find the fault if it trips again. There are many empty opening faults with a long service life, and they should be replaced in time.

If there is a multimeter at home, it means that you have the ability to do it, first disconnect the air open, disconnect all electrical appliances, confirm that the socket has no voltage, measure the resistance with the resistance gear, there is a short circuit, there is a problem with the line, disassemble the socket, and check one by one.

1.A short circuit in the power supply generally does not affect the electrical appliance.

2.Disconnect all switches, unplug all sockets, and use a 500V megohmmeter to check the insulation between lines or between phases.

3.It is recommended that you check the socket board of your computer.

It can be found by open circuit, and there is no way to find the drop when short circuit. After the short circuit, it is the fire line and the zero line get along.

The test pen can be tested if it is electronic, and the other party in the next paragraph will not emit light, and this place is the focus of the problem.

Please wait a moment.

If it is a short circuit, there is a multimeter can be measured, first disconnect the total power supply, measure the resistance value of the zero line and the live wire and the ground wire, the small resistance value is the way where the short circuit phenomenon occurs.

Questions. The wires that have just been installed in my house are not lit, and each wire can measure electricity.

Is it for other reasons.

You double-check that other switches or wires are not loose.

You double-check that other switches or wires are not loose.

It may belong to the phenomenon of zero line breaking, I don't know your specific wiring, I can only tell you the general inspection method, you first use a voltage tester to check whether the incoming line is normal (normal is a line is bright, a line is not bright) especially the fuse or air switch at both ends of the incoming line, to determine whether the zero line has been introduced. Just start looking for it along the zero line, as long as you find a section of the handover that is bright and not bright, it is the fault place. In addition to the problem of the terminals, there is also the problem of the wires, and I have encountered wires with disconnected copper wires in the middle of the wires.

For the sake of safety, you'd better find someone to be a guardian for you

Questions. From the empty unpacked, connect a neutral wire or live wire separately, and then test that there is electricity on the socket.

You check the zero line again.

It may be that the zero line is broken.

Questions. The wiring is like this, the air conditioner in each room goes alone, the switch socket has a downlight, and the light strip is paralleled.

Is the zero line connected to the distribution box?

Questions. The neutral line is connected to the distribution box.

There is electricity at the air conditioning socket.

It's just that there is no electricity on the light socket.

That's the problem with your light socket.

Is it the reverse connection?

Or the switch is wrong and the power is not connected.

It is recommended to find a professional electrician to avoid danger.

To check for short circuits, you need to use a multimeter to check the path of the wire, and you can't work with electricity, which is very dangerous. It is best to find a professional electrician for repairs.

If you're short in your mind, it's best to find one that short-circuit sensor and you can find it out at a glance.

First of all, turn off all the electrical appliances in the house, and remove all the plugs.

If the live wire and the protection wire are short-circuited, the total power supply needs to be disconnected, and the multimeter is used to detect the situation between the live wire and the ground wire of each socket. After the operation, you can turn on the main switch to see if it will trip, if it also trips, it means that the main line is short-circuited.

When a short-circuit fault occurs in the line, you can use the insulation resistance tester to test and detect, and then find the short-circuit point and short-circuit equipment along the line. Once the fault point is found, it can be dealt with accordingly.

In our daily life, we often cause short circuits in wires due to improper use, and short circuits in wires are very dangerous things and even cause fires, so we usually pay special attention, but many people don't know how to check the short circuits of wires at home, what to do? Let's take a look at how to check and solve the short circuit of the wire!

How to check for short circuit of wire:

1. If there is a short circuit in the wires at home, first of all, all the electrical power must be turned off, and the plug should be unplugged.

2. If it is a short circuit between the live wire and the ground wire, it is necessary to close the main gate, and use a multimeter to measure the situation between the live wire and the ground wire of each socket, if it is passed, it means that the live wire and the protection wire are short-circuited, so that you need to find the socket one by one.

3. The above are confirmed, you can try to turn on the main switch to see if it will trip, if it will trip again, it is a short circuit in the main line, you can look at the places that are easier to short circuit on the main line, such as: some joints and plugs, etc.

4. If the main switch will not trip, it is recommended to open the electrical appliances at home one by one to eliminate it, and when the main switch is turned on, the main switch will jump, which is the question of which line.

5. You can also connect the power supply to the general electric hair to check, which is the loss of the family, the electric pen test live wire will be bright, the zero line will not shine, if the electric pen test the live wire and the zero line will be bright, it means that the zero line is broken, if the live wire and the zero line are not bright, then the fire line must also be broken at this time.

What to do if the home wire is short-circuited:

1. Disconnect the main switch at home, and then gradually hit to find the fault point to carry out the corresponding measures, if it is a three-phase short circuit, use a multimeter to detect whether the gear between the items is short-circuited, if it is a 220V short circuit, you can detect whether the items in the three-phase and the zero line are short-circuited.

2. After the fault line is repaired, the line can be reconnected and insulation measures can be taken; Check whether the insulating skin of the cable is aged, or use the shake meter to detect whether the insulation resistance value is within the safety limit, if it is a short circuit in a humid environment, please pay attention to the use of waterproof insulation measures. Then use the universal meter again to measure whether there is a short circuit, and if there is no problem, it can be used normally.
