Can the lighting cable and the socket wire share the neutral wire?

It depends on the distribution box at home.

Switch installation, such as the lighting and socket are a loop, can share a zero line, if not the same circuit, basically use the IP air open, can also share a zero wire, not the same circuit, use the leakage switch.

In this way, a neutral wire cannot be shared. Pass the leakage protector.

The working neutral line cannot be mixed with other circuits, and other circuits cannot be used by the neutral line of the leakage protector load.

Therefore, for the sake of safety, the zero line of each circuit in the home is best not to share, if it is divided into multiple roads, it is easy to find when the road fails, and if it is difficult to find, it is at most that there is no electricity in this road, which will not lead to no power in the whole house.

1.Lines, sockets and lighting equipped with leakage protectors cannot share the neutral line;

2.There is no line with a leakage protector, and the socket and lighting can share the neutral line.

For new home decoration, it is best not to install it in this way, the socket lighting is separated, and the sockets in different places should also be controlled separately with different leakage protection, so as to facilitate troubleshooting in the future. It's not like all of them have no power.

If it's not the same route, not the same circuit, you can't share the zero line, I hope it can help you.

The neutral wire is shared, so the lighting wire and the socket wire can share the neutral wire.

In view of your problem, because in the lighting line, and the socket, they are all 220V into the line of the house, so their zero line is the same, the only difference is that the socket is grounded, the socket is with a leakage protector, and the lighting circuit is without a leakage protector, the specific need to be installed in the line on the spot, I hope to help you, this is just an opinion.

The zero line of the socket and the zero line of the lamp can not be shared, this depends on the circuit division of the lighting and socket in our home, the zero line of the socket and the zero line of the lamp are divided into two situations in the home circuit, one is that the zero line of the socket and the zero line of the lamp do not share the zero line, I rented a new one next to the company, I just moved last weekend, and I was so tired that I didn't want to move. But the more disturbing thing is still to come, the house actually tripped, everywhere was dark, I tossed several times, but it was too late and I couldn't find an electrician, so I could only make do with it first. can share a neutral line.

If the socket and the lighting are not the same circuit, and both leakage switches are used, the neutral line cannot be shared. Because the working neutral line of the leakage protector cannot be mixed with other circuits, and other circuits cannot be used by the neutral line on the load side of the leakage protector.

If the distribution box in your home is only installed with a leakage protection for the main switch, and the rest of the branches are all air switches, then, in this kind of installed home circuit, any neutral wire can form a load circuit with another live wire. Whether the zero line of the lamp and the socket can be shared, it depends on the circuit division of the home, one situation the zero line of the lamp and the socket is shared, as long as the power is tripped as soon as the power is transmitted, one situation can be shared.

If the main switch is an air switch, an air switch for circuit lighting, and a leakage switch for socket protection, the zero line cannot be shared, and the zero line should be used with the zero line of their respective circuits; One power supply adopts the wiring method of one fire and one zero tube, which is convenient for maintenance and replacement of lines. The socket is a leaky power supply, so the neutral wire cannot be shared. The common zero line will trip, the general household is a total leakage protector, divided into multiple single P circuit breakers, my suggestion is that you check is a leakage control line, can share the zero line.

The power supply of the socket is generally only controlled by the power switch (leakage protector switch).

At this stage, the first commonly used wiring method of home circuit layout is that the lighting in the home is a circuit, which is controlled by the air switch alone, and the rest of the sockets are divided into circuits according to different functions, for example, the common circuit division mode is a single circuit of ordinary sockets, each air conditioner is a separate circuit, a single circuit of kitchen sockets, and a single circuit of bathroom sockets, all of which are controlled by their respective leakage protection switches; This lighting circuit and socket circuit are controlled by their respective air switch and leakage protection switch in the circuit, the zero line of the socket and the zero line of the lamp are not allowed to be shared, otherwise it will lead to the leakage protection switch tripping;

Of course, the neutral wire in the socket and the neutral wire on the lamp can be shared, as long as it is separated from the same main neutral wire, which is completely worry-free.

I cannot share it. Because the current is safe to use cross-current, if it is shared, it will cause too much wattage of electricity generated when using electrical appliances in the home, which will scorch the wires and easily cause fires.

When the socket is working, the current starts from the live wire of the leakage switch through the electrical equipment and then returns from the zero line back to the leakage switch, and the leakage switch can work normally. When the lamp is working, the current is turned on from the 1P empty and returns to the N row through the lamp, and the lamp circuit can also work normally. Except for general lighting in the kitchen and bathroom, the neutral line of this lighting is not allowed to be shared with the neutral line of the socket.

At present, there are two types of wiring methods for home electrical boxes, one is the main switch based on the leakage protector, and the other is the main switch based on air opening. Let's explain separately, now the split line, such as the lighting power is smaller, the wire is smaller, such as the low plug to be able to withstand the microwave oven, several kilowatts of oil heaters, the wire should be thicker, if you mix the zero line of the socket on the thin line of lighting, the lighting line will also bear high power. Nowadays, most of China's residential electricity use adopts a fire and a zero (single-phase 220V) power supply mode, and after entering the electric box, it is controlled by an empty open or leakage protector as the total circuit breaker, and all electrical appliances are restricted by the fire zero line.

If it is a leakage protector under the control of the zero line and live wire, you can use, I will give you an analogy, a leakage of the line out of the mouth, you are divided into eight ways, divided into ten ways of electricity and finally have to pass a leakage protection. The maximum wattage of lamps and lanterns in the household electricity of self-built houses will not exceed 100 watts, and it is more common between 18 and 30 watts normally, and the entrance line is usually 4 square wires, and all the electricity consumption areas are controlled by a gate knife switch, and the leakage switch is combined with the electricity meter. In the distribution mode of main gate air switch and shunt leakage protection, the zero live wire of the lamp is the zero live wire of the socket.

If the neutral line of the luminaire and the socket are different, the leakage protection will trip. It's just that you can't borrow zeros between the branches. Our home entry lines are all single-phase three-wire, one live wire, one neutral line, and one ground wire.

In this sense, all household electricity neutral wires are shared, whether it is an outlet or a lighting.

No, generally the neutral line and the live wire are shared, and the sharing of the neutral line and the neutral wire will cause the current to become smaller, and the normal power supply effect of the electrical appliances cannot be achieved.

It can be shared, because it comes according to the route of electricity, and if there is only one knife switch control for a route, it can be shared.

Although it is theoretically possible to share, it is best not to share the power of the lamp and the socket, as this can lead to accidents and bring safety hazards.

It is best to divide a few more circuits in the home decoration circuit, and the zero line of each road is not shared, so that it is convenient to check the line fault in the future, even if the problem can not be found, at most there is no electricity in this way, and it will not affect the whole house without electricity.

If the lamp and socket are a circuit, you can share a zero line, if it is not the same circuit, the basic IP is empty, you can also share a zero line, not the same circuit, the leakage switch is used, so that you can not share a zero line, because the working zero line of the leakage protector can not be mixed with other circuits, and other circuits can not borrow the zero line of the load of the leakage protector.

Therefore, for the sake of safety, it is best not to share the various circuits in the home, if it is divided into multiple circuits, so that it is easy to find when the line fails, and if it is difficult to find, it is at most that there is no electricity in this way, which will not lead to no power in the whole house.

If the total protection switch in the multi-circuit distribution box is a leakage switch, but the socket protection circuit is not a leakage switch, in this theory, the zero line can be shared, but not just for the present, you need to consider future maintenance, replacement lines and other reasons can not be shared with the zero line, which will be very troublesome;

If the main switch is IP air open, the circuit lighting is also IP air open, and the socket is a leakage switch for shunt protection, and the zero line cannot be shared, so it is also recommended that a power supply adopt a live wire and a zero line connection, which is convenient for later maintenance.

However, from the perspective of strict specifications of circuit connection; The zero line of the socket and the lighting fixture must be separated, because the wire of the home distribution socket is generally larger than the wire of the lamp, so the current value of the matching leakage circuit breaker is also different, so as to ensure the safety of the circuit. (For example, a copper core wire with a cross-sectional area of 4 square millimeters matches a circuit breaker with a trip current value of 25A "leakage circuit breaker", and a circuit breaker with a copper core wire with a square cross-sectional area with a trip current value of 16A or 20A) Therefore, wiring in strict accordance with the regular circuit specification is the safest

In fact, the lamp and socket share a neutral wire, which does not have much impact on themselves, but may cause the problem of tripping

Same circuit.

If the lamp and socket are controlled by a circuit breaker on the same branch, in this case, the neutral wire itself is common, and the neutral wire of the lamp and the socket can share the neutral wire.

Different controllers.

If the lamp and socket are controlled by different circuit breakers, the 1P air switch can be shared in this case, but it is not recommended to use this way, because it will affect the protection of the circuit breaker against the neutral line, resulting in overload and non-operation.

If the lamp and socket are controlled by two circuit breakers, and both leakage switches are used, then the neutral wire cannot be shared. Regardless of whether the neutral line is connected to the leakage circuit breaker or not, when the neutral line is working, it will definitely cause the current of the neutral line and the live wire to be different, which will cause the circuit breaker to trip.

Since the live wire is used in the living room switch, the zero line can also be followed from the living room lamp head, and the control line of the switch will have a tube, and the zero line on the lamp head will be worn down from the tube of the control switch, and then back to the spotlight. In this way, the layout of the spotlights and the living room lights on the same line is formed.

Please make the question clearer:

Do you use spotlights with rectifiers or transformers?

The living room switch you use, the spotlight and the living room light can only be turned on one, is one switch to control the spotlight and the living room light at the same time, or is it used to use two switches to control them separately? Which one is on? Or is the spotlight on for a while and the living room light on for a while?

How many wires are there on the switch of your living room light to the lamp head?

Are your spotlights and living room lights installed in the living room?

Find an electrician to do it, you can use the zero line of the living room lamp to light the spotlight without affecting the living room lamp, but it is best to find an electrician to do it.

Your decoration has ended, if you don't want to change the line, just change the gate box, the lighting all the way to the zero line of the fire line are connected to the leakage protection, your lights can be used normally, but if the leakage action, the lighting socket is all off power, if it is at night, the light is blind

Find an electrician to check it carefully, I guess it was connected to the protection zero line of the socket, causing the leakage protection switch to lose power.

A set of spotlights? How many? All use the group, need to be separately out of the line, the home air open, a current limit is very small, the electrician who arranged the wire for your home did not make a current estimate to arrange the line?

If you use a square line, your spotlight is counted as a 50w, don't exceed 10, you ask the electrician to change the main line where your spotlight is located to a larger point, this problem is likely to be your home, the lights are on, and then add the spotlight, the instantaneous current over the air open protection value, immediately jump to explain. (The premise is to make sure that the line is fine) and then check whether the branch point is connected.

Hope it helps.

First of all, the zero line of the socket can never be used as the zero line of lighting, because the socket has passed through the leakage protector, and the lighting will cause leakage!

I don't know where your spotlights are installed, usually the spotlights are placed on the ceiling, but you said that the zero line of the socket is used, and there should be no socket at such a high position? Even the air conditioning socket won't be that high, right?

If the spotlight is installed on the ceiling, you can connect the spotlight with the zero line along the ceiling lamp, and then connect the spotlight control line to the switch.

Because the general office space and other places are divided into two circuits, lighting electricity and power electricity, which are controlled by different switches. In order to facilitate control, the indoor neutral line is shared when it enters the household's home from the meter box.

If there is a shunt control air switch in the room, the socket is used for the air opening with leakage protection, the lighting is a monolithic circuit breaker, and the zero line of the socket and the zero line of the lighting including the live wire cannot be shared, because it is not a circuit and will trip.

If there is a distribution box, the live wire is controlled separately, and the power supply is provided separately, and if you want to use the neutral line, you need to connect the neutral line of the socket and the neutral line of the lighting to the outgoing end of the neutral line of the total empty opening of the household in the distribution box.

From the perspective of safety standards, each should be separated, especially the large capacity and the small capacity should be separated. In principle, all electrical appliances can share a zero line, mainly to see whether the capacity of the zero line (circuit) is enough, to calculate the total amount of current when the electrical appliances are all working, if the total amount meets the allowable current of the wire, there is no problem. In addition, the wiring should pay attention to the reliability of the joint part, and the problem is mainly here.
