Why is there electricity in the live wire of the electrical appliances at home and no power in the n

Why is there electricity in the live wire of the electrical appliances at home and no power in the neutral wire! Can't use the dot pointer? ”

There are generally two types of situations where electrical appliances cannot afford electricity:

In the first case, if the electrical appliance is normal, it means that the appliance is broken, and you can ask a friend to help repair it, or take the appliance to the repair shop to repair it.

In the second case, it is generally a circuit failure, such as an open circuit of the zero line, and the electrical appliance cannot be used because the current cannot form a loop. This requires a little basic knowledge of electricians, with the help of a multimeter.

Careful inspection is usually due to the presence of false joints or oxidation disconnections on the joints of the neutral line.

If you don't have an electrician foundation, it is recommended to ask an electrician master to help, so that you can avoid detours, after all, no electricity will bring a lot of inconvenience to life.

If the live line is electrified, the zero line is not electrified, and the zero line is not electrified, and the electrical appliances cannot be used, then it is not normal, the problem is likely to be on the zero line, and the zero line has poor contact.

The live wire has electricity, and the neutral line has no power, and this is the case under normal circumstances. If the electrical appliances are not used, it is not normal. The problem is likely to be on the neutral line, which is typical of a broken neutral line. If you follow the wire to detect, there will be breakpoints, or strict contact with bad places for you.

I think that the electrical appliances in your home have no electricity, so you have to find an electrician to pay for the line that comes in from the outside meter to find the reason, so that the zero line of the fire wire can have electricity.

Please check if the neutral line is broken, and the device does not have various circuits. If you use leakage protection switches at home, the store can't deliver them.

There is electricity in both the live and neutral wires of the home circuit, however, so household appliances are not usable. This happens for the following reasons:

Home circuits. 1. The zero line in the home circuit has poor contact or open circuit fault!

2. Refer to the figure above, if there is really a fuse in the line, it may be that the fuse is in poor contact.

The way to inspect the repair is:

1. Use a multimeter to detect whether the power supply voltage at the upper port of the knife switch is normal?

2. Is the power supply voltage at the lower port of the fuse normal?

After such an inspection, you will definitely be able to find the problem!

Be sure to pay attention to safety when inspecting and repairing!

The first reason: the neutral line is broken. For example, when we send electricity, turn on the light switch, if the light is not on, then we use a pen to measure the 2 binding posts of the lamp, if the live wire and the neutral wire are live, 100% of the neutral line is broken and the neutral line is live.

Solution: Check the position of the lower zero line connector, see if the lower connector is not connected well or whether it is missing, check the position of the lamp head, and see if the lower zero line falls off.

The second reason: switching the zero. For example, after we send electricity, turn on the light switch and the light can be turned on normally, and when the light switch is turned off, we use a pen to measure the 2 binding posts of the lamp.

Solution: normal control of the light, the switch to control the live wire, if the control of the zero line is not safe, in this case, we have to adjust the zero line and the live wire, the zero line to connect the light, the live line switch, or we can adjust the zero line of the live wire under the electric switch.

Hello, this is because the neutral line is broken, and under normal circumstances, the electricity on the live wire will reach the neutral line through the electrical appliances and form a loop. If the neutral line has zero potential, it can form a current, and the electrical appliance can work. If the zero line is not connected, it will become the same potential as the live wire, and the test with the electric tester will show that it is electrified, and at the same time, it cannot form a loop, so there will be no current, so the electrical appliance will not work.

You just ask the electrician to connect the neutral wire. I hope it can help you, I wish you all the best, and I look forward to your praise, thank you!

In this case, most of them are faults caused by disconnection of the neutral line. If you use a knife switch at home, you can directly check whether the neutral fuse of the knife switch is blown out; If it is an automatic switch, find the zero line broken line step by step, and deal with it.

There is electricity in the live wire (phase wire) and neutral wire (neutral wire) of the electrical circuit at home, but the electrical appliances cannot be used. This phenomenon is that the neutral line is not connected, and the electricity of the phase wire returns to the neutral line through the load; The electrical appliance cannot be used because the voltage applied to the appliance is 0 or very low, and the appliance cannot work properly.

The biggest possibility is that the zero line is broken, and if the zero line is broken, it will be connected to the live wire through the electrical appliances, resulting in the zero live wire being electrified.

In this case, the neutral line is usually broken.

Check whether the input terminal of the knife switch (main switch) is normal, and whether the output terminal is normal.

The zero line of the live wire has electricity, so of course it can't be used. Electricity needs to form a loop before it can be useful. If you have a multimeter, measure the zero live wire, there should be no voltage.

The neutral line is broken, when the live wire switch is turned on, the neutral line of the live wire has electricity, but the electrical appliances cannot be used.

In this case, there is a high probability that the zero line is broken. And based on what you've described, it seems that the neutral line is broken closer to the main switch.

Summary. When the neutral wire is electrified, it is generally the live wire that is grounded or touches a metal object. The electrical appliances cannot be used because the live wire is grounded and cannot be used with protection.

There is electricity on the zero line of the electrical circuit at home, but the electrical appliances cannot be used.

Hello, this is a short circuit, it may also be the live wire grounding, to cut off the power supply, find the switch box**short circuit,**live wire grounding.

When the neutral wire is electrified, it is generally the live wire that is grounded or touches a metal object. The electrical appliances cannot be used because the live wire is grounded and cannot be used with protection.

When did it start and how did it happen.

If there is only a live wire and no neutral wire, electricity cannot be used. This is because a closed loop needs to be formed in the circuit, including the power supply, load and wire, etc., and when any of these links are missing, a reliable closed loop cannot be formed.

If there is only a live wire and no zero mode and wire, it is recommended that you do not turn on the power supply at will. Here are a few ways you can consider:

1.Find a professional electrician or technician for consultation and processing. They will have a better understanding of how to use such circuits safely.

2.Contact your electric utility or local** agency for advice and guidance. They can provide professional advice and assistance.

3.Find other devices that meet safety standards to replace those that require electricity. For example, you can choose to use a cordless product or a product with an adapter plug.

In short, it is dangerous to try to use a circuit that only has a live wire and no neutral wire, so be sure to be cautious and keep an eye on it.

Only the live line does not have a trapped section zero line and cannot be used. It is common sense that the current needs a loop.

If you are not afraid of danger and breaking the law. You can do the ground wire instead of the zero wire. However, if there is a Wang Yuyu meter, it will not affect the electricity metering.

Two wires, namely the live wire and the neutral wire, are used to ensure the normal operation of the circuit. If there is only a live wire and no neutral wire, it may cause the circuit to be unstable or cause a dangerous situation such as electric shock. Therefore, it is recommended to make sure that both the live wire and the neutral wire are used when using two-phase electricity.

In general, the live neutral line is caused by the disconnection of the neutral wire. After the neutral line is broken, the neutral line can also make the electric pen shine due to induction, or the live wire will reach the broken neutral line after passing through the electrical appliance, then the neutral line will be electrified.

Another situation is that the zero line contact is poor, the resistance is relatively large, and there will be a voltage difference between the zero line and the ground. The live wire is live because the live wire is connected to the power supply, and the neutral wire is not connected to the power supply, so the live wire is electrified.

The zero wire is connected to the live wire, and the live wire is connected to the zero line, and there is a problem like yours.
