Can a 220v10 kW main line use two 4 square live wires and one 4 square neutral wire?

Hello: Can 220v10 kW main line use two 4 square live wires plus one 4 square neutral wire. 220V10 kW current is about 50A, the main line can use two 4 square live wires, and the zero line can only be used with two 4 square wires.

The current is equal on the wire, the live wire, the neutral wire. No, you can't use a 4 square zero area, which is not enough, and it will burn out after a long time.

Yes, but it must be a national standard multi-strand copper wire. The cross-sectional area of the neutral wire can be used normally when it reaches half of the cross-sectional area of the live wire, but 10 kilowatts of at least 40A+ current, two 4 square multi-strand copper wires can withstand 40A current, but it must be careful not to overload the operation and the correct way of double live wire paralleling.

No, the main line is recommended to use 1o square live wire and neutral line, if you use 2 4 square live wire and 1 4 square live wire to do zero line, when the full load operation is easy to make the cable production. Heat forms a short circuit, so it is recommended to use a 10 square two-core sheathed cable as well.

If you have a three-phase power supply, it is okay to use two 4 square millimeters live wire and one neutral wire, but there will be a three-phase imbalance problem with an empty one-phase live wire, it is best to add a live wire so that all three phases can be used. If there is only a single-phase power supply with a 6 square millimeter live wire and a neutral wire, 4 square millimeters can barely be used, and two 4 square millimeter wires can be connected together.

10000/220=

Square. Therefore, if the wire diameter is not enough, two 16 square wires should be used. 10 square meters are not thick enough, barely enough, and the line will be burned if there is a slight void.

No way. The wire is too thin, it is recommended to use 10 square copper wires or 4 copper wires of 4 squares...

4 square wires are too thin, so you have to use 10 square copper wires.

The 10 square zero line and other 10 square three live wires are used at the same time, with 220 volt electrical appliances, can you use 50kw at most, and the 10 square line with three 10 square lines in Qizhou Qinghe, and at the same time with 50 kilowatts, can the zero line withstand it?

If the current carrying capacity per square is 5 8A, 10 square copper wire can carry 50 80A. That is, the maximum initiation of each phase can carry a load of 220 50 80 = 11000 17600 = 11.

If the three phases are balanced and all are pure resistive loads, 10 square copper wires can carry a total load of 50 kW.

If the three phases are balanced, the neutral current = 0;If the three phases are unbalanced.

The neutral current is never greater than the current of the maximum phase. Therefore, the zero line can withstand it completely.

Generally, the usage of copper wire is 6A square, 10 square copper wire, can carry more than 60A load, this should consider the distance of the line and the way of erection, the distance is not large, and the current can even reach 90A; In this way, the laughing wheel can be used for more than 13kw per phase. If the three-phase four-wire system is supplied with electricity, it is 13kW 3 or more.

10 square copper wire, at 220V voltage, the maximum load is kilowatts. Three-phase four-wire system, the maximum power is kilowatts.

However, this is in the case of copper wire socks must meet the national standards, in reality, many copper wire standards, there is a gap. At this time, it is not suitable for a load of 50 kilowatts, which is dangerous.

In the case of three-phase equilibrium, the zero line is no problem.

1 square copper wire can carry 6A current, 10 square is 60A current, three-phase four-wire can carry 220V electricity about 17 kilowatts, 10 square zero line and other 10 square three live wires at the same time, with 220 volt electrical appliances if the balance zero line between the fingers is not current, completely Wang Que can carry.

Ten square copper wire three sedan four wire can be with 220V, how many kilowatts ten square this zero line and other ten square three fire potato fighting line number rock at the same time with 225 electrical, this should be usable, the funds should be used in the silver quietly can be brought this 5w of 5kw, this should be able to bring.

Hello: 1, the copper wire of the [Safe ampacityfor6a/mm², 10 square copper wire is60a

Single-phase resistivityElectrical appliances [1kwEvery phase is hiddenCan be loaded13kw

Three-phase simultaneous use can be loaded39kw3. The ruler carries the circleInductance] with electrical appliances [The power factor is different], should be toThe rated current is a reference, and the current of each phase should not exceed 60A

You should first calculate the total current of the electrical appliances, and then select or material cables and wires after grinding, check the manufacturer's ampacity meter, and then consider the design coefficient such as laying methods and environmental conditions.

10 square copper core cable current carrying capacity 60A 220V 1KW = 60 can carry 13KW load.

Such lines can be supplied with 220 v21 kW power or 40 kW pure resistive load.

It is not explained how the line is laid and whether it is a BV copper core wire pin. Lose your hand.

Regardless of the voltage drop of the line, the total load should not exceed 33kW in the case of single-phase 220V load and three-phase carrying load balancing.

The current carrying capacity of 10 square copper wire is 50 60A, and the load is about 26400 31680W

Summary. When the wire is pressed indoors, the live wire is 4 square, and the neutral line is squared.

Whether it is a 4 square millimeter wire for the live wire, a square millimeter wire for the neutral wire, or a square millimeter wire for the live wire, and a 4 square millimeter wire for the neutral wire, the effect is the same, and this circuit can only calculate the current according to the square millimeter wire.

The square copper core wire allows long-term load current of: 16A-25A, the maximum current of the whole circuit shall not exceed 25A, conservative calculation of power according to 16A, if the voltage is 220V, the allowable long-term power is 220 16 = 3520 watts.

However, the cross-sectional area of this indoor wire can only be calculated in square millimeters.

Because these wires are connected in series with electrical appliances, as long as there is a section of wire cross-sectional area of square millimeters, the cross-sectional area of the whole circuit wire can only be calculated by square millimeters.

The wires are combined with 4 square live wires, can the square neutral and ground wires work?

When the wire is pressed indoors, the live wire is 4 square, and the neutral line is squared. Whether it is a 4 square millimeter wire for the live wire, a square millimeter wire for the base neutral wire, or a square millimeter wire for the live wire, and a 4 square millimeter wire for the neutral wire, the effect is the same, and this circuit can only calculate the current according to the square millimeter wire. The square copper core wire allows long-term load current to:

16A-25A, the maximum current of the whole circuit shall not exceed 25A, conservative calculation according to 16A to calculate the power, if the voltage is 220V, the allowable long-term power is 220 16 = 3520 watts. However, the cross-sectional area of this indoor wire can only be calculated in square millimeters. Because these wires and electrical appliances are connected in series, as long as there is a section of wire cross-sectional area is Fengzhi Zheng square millimeter, the cross-sectional area of the whole circuit wire can only be calculated by square millimeters.

Extended information: If the cross-sectional area is calculated by 4 square millimeters, the current does not burn out the 4 square millimeters of wire, but burns out the square millimeter of wire first. Several circuit elements are connected to each other along a single path, and each node is connected to a maximum of two components, which is called series connection.

Circuits that are connected in series are called series circuits. The current flowing through each resistor in a series circuit is equal. Because each section of the same branch in a DC circuit has the same current intensity.

The switch controls the entire circuit at any location, i.e. its role is independent of its location. There is only one path for the current, and the current that passes through one lamp must pass through the other. If one light goes out, the other must go out.

Advantages: In a circuit, if you want to control the circuit of the good trace, you can use the circuit in series; Disadvantages: As long as there is a disconnection, the whole circuit becomes an open circuit, that is, the electronic components connected in series cannot work normally; Distinction:

There is no bifurcation in the wide parallel circuit.

This is my answer, I hope it is helpful to you, thank you.

The 4 square live wire can not be matched with the square neutral line, and the 4 square copper wire is small, which is difficult to meet the requirements of use; The wire diameter of the live wire and the zero line must be consistent, and the 4 square live wire with the square zero line and the square live wire with the square zero line are wrong, and they are resolutely not allowed in home improvement.

In order to make the alternating current have a very convenient power conversion function, usually the power transmission is in the form of three-phase four-wire, the three ends of the three-phase electricity are called phase wires, and the three tails of the three-phase electricity are connected together and called neutral wires"Zero line"。The reason why it is called the neutral line is that there is no current passing through the neutral line at the time of three-phase equilibrium, and then it is directly or indirectly connected to the earth, and the voltage with the earth is close to zero.

The earth is a good conductor, and the ground wire is short-circuited to the earth through a deeply buried electrode. The transmission of mains power is in a three-phase way, and there is a neutral wire, and the current of the neutral wire is zero when the three-phase is balanced, commonly known as it"Zero line"Another feature of the neutral wire is that it is short-circuited with the ground wire in the total distribution input of the system, and the voltage difference is close to zero. The three phase wires and the neutral line of three-phase electricity have a voltage of 220, which will produce electric shock to people, commonly known as it"Fireline"。

Reason for the live life of the neutral line.

1. There is current: this is caused by three-phase unbalance.

2. There is voltage: this is the zero line is broken, which is very dangerous and easy to cause damage to electrical equipment, which must be overhauled.

For the live neutral line in a three-phase four-wire system (TN-C) system, most of them are caused by the unbalanced load of the three phases, and the neutral line will be energized in the fault state.

However, in the three-phase five-wire system (TN-S), the neutral line generally carries a very weak current, especially in the power supply of the computer system, this is because the working voltage of the computer system is a micro voltage generally between 0 5V, and it is also a DC power supply, so according to the working principle of the DC system, its zero potential is a current through;

The DC zero potential in the computer is to use the zero potential of the incoming power supply AC as the zero potential point of DC through DC AC conversion, so the zero line in the power line in the computer system is normally microcurrent through, so the leakage protection device is not installed in the computer power distribution design.

We all know the importance of the grounding wire, which can prevent accidents caused by electric shock, but have you ever understood how many squares of the ground wire should be used?

**At first, I didn't understand much, when I accepted the water and electricity, the live wire and the zero line on my socket were 4 squares, but the yellow and green lines were squared, and I seriously suspected that my family had encountered a fake electrician!

Because I look at other people's sockets, they are all as thick as the neutral wire, live wire, and ground wire. But the master told me that it was too wasteful to use 4 square wires to ground the wire. After all, there are very few owners who really understand electricity, in fact, according to the provisions of the building electrical construction code, the socket wiring, the left zero and the right fire grounding, the ground wire is not allowed to be less than 1 2 of the phase wire.

**That is to say, when the neutral wire and the live wire in the socket are 4 square, the ground wire is the smallest, which is more reliable. And if your live line and zero line are 16 square, 1 2 is 8 square, but there is no 8 square, 10 square is the most appropriate.

**The specific number of square meters to use for the ground wire is determined according to the amount of electricity used by the company, and there is no unified standard.

In addition, many people may think that it is safe after connecting the ground wire, and when accepting the water and electricity, it is important not to forget to detect whether the ground wire is in normal working condition, otherwise how many ground wires you connect are safe in vain!

**How to check whether the ground wire wiring is valid?

1. Detect with the help of the function of measuring voltage of the universal meter.

**Adjust the initial data of the universal meter to the voltage gear 750V, and then use one meter pin of the universal meter to touch the live wire of the socket, and the other to touch the ground wire, if the reading of the universal meter is close to 220V, it is normal, if it is less than 220V, it means that the ground wire is not in working condition.

No, I've consulted experts on this issue. Square for lighting, square for sockets, 4 square for kitchen and bathroom. It's both reliable and safe.

The current passing through the live wire and the neutral wire is equal, and the same wire should be used, there is no need to use it this way! If it must be used in this way, the rated current of the line can only be considered according to the square line, so it is a bit wasteful to use 4 square wires for the live wire.

The live wire is 4 square, the neutral wire is squared, and the maximum current that can only pass through the square wire. It's about 12a.

The neutral wire of the 220V single-phase electric live wire must be the same, because the current of the live wire is the same regardless of the neutral line.

The current of the neutral and live wires is the same! It can only be used at 2.5!

I want to ask, is it okay to use 4 square meters for a section of fire line in the kitchen and a square line for the zero line?

Home circuit: Is it okay to use 4 square wires for the live wire and square wires for the neutral wire?

Not too much power Absolutely.

Answer: First of all, it can be determined that no matter what the line is, the neutral wire and the live wire must be the same thickness, otherwise the wire will burn out once the load at home is high. As for the ground wire, as long as the wire at home does not exceed 16 square meters, the ground wire must be as thick as the fire wire, which is the standard for the thickness of the ground wire, and the same is the same thickness as the zero wire fire wire and the ground wire.

And the friend wire circuit is obviously not more than 16 square, that is to say, the square ground wire is naturally not very safe, simply put, the live wire of the friend's socket is 4 flat, then the zero wire and the ground wire should also be 4 square, if the live wire is square, then the zero line and the ground wire should also be flat.

Hope it helps, dear
