After turning off the lights, are there still electricity on the two wires that connect the lamphold

Turn off the light, the two wires under the lamp holder are not electric, because the switch of the light is mainly to control the power supply of the two wires under the lamp holder. When you turn it on, two wires are energized, so the lights are on, and when you turn it off, both wires are powered off, so the lights are off.

When installing the wire, we should pay attention to the correct wiring method, and avoid the joint in the process of installing the wire, if the joint will cause a large resistance, then the wire will heat up.

If there is a wire joint, in order to avoid accidents, the wire joint should be wrapped with insulating tape.

Electrical Safety Precautions:1. It is forbidden to move household appliances by hand, such as table fans, washing machines, televisions, etc.

2. It is forbidden to repair live lines or equipment at home with bare hands and feet.

3. It is forbidden to touch with wet hands or wipe lamps, switches and other electrical appliances with wet cloths.

4. It is forbidden to change the three-prong plug to a two-prong plug at will.

5. It is forbidden to pull and connect wires indiscriminately.

6. It is forbidden to add electrical appliances to the original line without permission.

7. It is forbidden to use unqualified electrical equipment.

8. It is forbidden to use electric irons and hair dryers unsupervised.

Electric stoves and other electrical appliances.

9. It is forbidden to set up private power grids for fishing, anti-theft, hunting, etc.

10. It is forbidden to use lead wire, copper wire and other substitute fuses for fuses. Wait a minute.

Hello: 1. After the power of the lamp is turned off, there is no voltage between the two wires connecting the lamp holder, butIt doesn't mean there is no electricity

2. Note: a. If the switch controls the neutral line, the lampholder will be electrified;

b. Even if the switch is wired correctly, the zero line will be charged under special circumstances!

c. Non-professionals, it is forbidden to contact the wire under any circumstances.

The regular installation method is that the switch is connected in series between the live wire and the lamp holder, after turning off the switch, the live wire is disconnected, and the neutral line is of the same potential to the ground, so it is not charged, therefore, as long as it is a regular installation, the lamp holder is not charged after turning off the lamp.

The wire that connects the lampholder is definitely electrified. Don't try it to avoid electric shock.

After turning off the lights, the lights are turned off with a single-wire switch, so that the installation switch is not completely closed, and he may be electrified, but the switch is set at the zero line and will be electrocuted.

This depends on the type of light switch you have and which line the switch segment is.

Our common daily household switch is a line of segments, according to the requirements of the specification, it is required to cut off the live wire, so that the lampholder is not electric, you can touch it with confidence, but it is not installed by professionals or the neutral line of fire is replaced, at this time you can also turn off the light, but at this time the lampholder is electric.

There are also some switches that are turned off by two lines at the same time, and this kind of lampholder is not electric, such as the kind of switch commonly known as "gate knife" that we commonly see, and there are also some switches such as relays and two lines.

Hello, I have seen your question and am sorting out the answer, please wait a while

Why is the light switch turned off, the lamp head, and the live wire still has electricity.

The light switch is turned off, and the live wire still has electricity, because the cut wire on the switch is connected to the zero wire, and it is good to replace it with the live wire. In the single-phase three-wire socket, the middle is the grounding wire, which is also used for positioning, and the other two ends are connected to the fire wire and the neutral wire respectively, and the wiring sequence is the left zero and the right fire, that is, the left side is the zero line, and the right side is the fire wire. All household appliances with metal shells use single-phase three-wire power plugs.

The three plugs are arranged in a regular triangle, and the longest and thickest copper plug on the top is the ground wire. The two below the ground wire are the fire wire (the symbol letter is"l"live wire), zero wire, the order is left zero and right fire.

This depends on the type of light switch you have and which line the switch segment is.

Our common daily touch and training household switch is a line of segments, according to the requirements of the specification, it is required to cut off the live wire, so that the lampholder is not electric, you can rest assured to touch and laugh, but it is not installed by professionals or the zero line of fire is replaced, at this time you can also turn off the lights, but this is the time when the lampholder is electric.

There are also some switches that are turned off by two lines at the same time, and this kind of lampholder is not electric, such as the kind of switch commonly known as "gate knife" that we commonly see, and there are also some switches such as relays and two lines.
