Can a 4 square copper core wire be connected to 2 air conditioners?

A 4 square millimeter copper wire can be connected to two air conditioners (the total power does not exceed 6800W).

The load of 4 square millimeters of copper wire is about 6800 watts, if the power of two air conditioners exceeds 6800w, then the load of copper wire is too large, which may cause fire. The total power range of 1 hp and hp air conditioner is 5400-6200W, which is less than 6800W, so two air conditioners can be used at the same time.

P.S. Under normal circumstances, the refrigeration capacity of 2200-2600W is called 1 horse.

3200-3600W for horsepower.

4500-5500W is 2 horses.

It can be used by two air conditioners, so you can rest assured. However, the power cord should be drawn from the 4 square power socket, and the square copper core wire for each air conditioner will do, and it is best not to use the power strip.

2 sets of 3 HP air conditioners with 4 square copper core wires are not good, it is best to use 6 square cables.

1. Because 2 sets of 3 HP air conditioners are about 38A, and the maximum current of 4 square cables can withstand 35A, it is recommended to use 6 square cables.

2. Wire diameter current reference :

The safe ampacity of the square millimeter copper power cord is 28A.

The safe ampacity, 4 square millimeter copper power cord, is 35A

The safe ampacities of the 6 square mm copper power cord are 48A

The safe ampacities of the 10 square mm copper power cord are 65A.

The safe ampacities of the 16 square millimeter copper power cord are 91A, and the safe current carrying capacity of the 25 square millimeter copper power cord is 120A.

A 4 square copper wire with two air conditioners is perfectly fine, and the approach you are going to implement should theoretically work.

Yes, because 4 square lines are enough for 2 air conditioners. Both of your options are fine, and the second option is better.

I can bring it to the touch.

The power of the air conditioner is about 1300W, but the air conditioner has electric auxiliary heat in winter, about 1500W, and the three air conditioners are about 4500W, and the current carrying capacity of the two phases of the 4 square copper cable is 30A, and the power that can be borne = 30 * 220 = 6600W, so there is no problem with normal use.

The power of the air conditioner is related to the energy efficiency ratio, the number of horses of the air conditioner indicates the input power of the air conditioner, 1 horse = 735W, and the power is generally converted to about 1300 watts.

According to the common current density standard, we can use 10 amps square millimeter as the current density of copper wire. Therefore, the cross-sectional area of copper wire is millimeters squared.

Well, a 4 square copper wire has a cross-sectional area of 4 square millimeters, so it has a current carrying capacity of 40 amperes.

Generally speaking, a horsepower air conditioner needs about 7 amps of current. Therefore, a three-horse air conditioner requires a total current of 21 amps.

It can be seen that the current required by the air conditioner of 3 horses exceeds the current carrying capacity of the copper wire of 4 square meters.

4 square copper wires are enough to carry 3 high-power horse air conditioners.

The rated current capacity of 4 square copper wires and the rated power of each air conditioner can be judged by the following calculations:

Calculate the current of each air conditioner: divide the rated power of each air conditioner by the supply voltage, which is usually 220 volts. For example, if an air conditioner is rated at 2 kilowatts, the current is 2,000 watts and 220 volts = amps.

Calculate the total current: Add the currents of each air conditioner to get the total current. For example, if each air conditioner is amps and you have 3 air conditioners, the total current is 3 * amps = amps.

Compare the total current and the rated current capacity of a 4 square copper wire: Compare the calculated total current with the rated current capacity of a 4 square copper wire. If the total current is less than or equal to the rated current capacity of 4 square copper wires, the wires are enough to carry 3 high-power horse air conditioners.

It is possible to drive, but it is better to use a larger one.

Dear, hello, 4 square copper core wire can not be connected to two air conditioners. The power of a 2 hp air conditioner is about 2000W, the maximum input power is about 2500W, the maximum input current is about 12A, the maximum input current value of two is about 24A, and the starting current value of one of them will exceed 25A, and the current value of two simultaneous starts will exceed 45A. Considering that if the air conditioner is equipped with an auxiliary electric heater, the auxiliary electric heater may be turned on when the heating is running in the severe winter season, and the maximum input current at this time will exceed the rated ampacity of the square copper wire, which is clearly stipulated in the national standard "GB T4706 1 2005", which is 25 32A - the allowable error in the national standard, so this specified value is an interval.

Therefore, as long as it is a qualified 4 square wire, its rated current carrying capacity will not be lower than 25A. When the two 2-horsepower air conditioners are turned on at the same time and the auxiliary electric heater is turned on, the maximum input current value of the heating operation has far exceeded the maximum carrying current value of the wire itself. Hope it helps.

Since the maximum current carrying capacity of 4 square copper wire is 32 amps, the maximum power of a 1p air conditioner is 1300 watts and the rated current is 6 amps. That is, it can be calculated that 4 square copper wires can be equipped with 4-5 sets of 1P air conditioners. However, in actual use, it is not recommended to let the copper wire run at full load, otherwise there will be overload, and it is recommended to leave some margin.

What are the tips for buying copper wire:

1. Good electrical conductivity.

First of all, when choosing copper wire, we should pay attention to its conductivity, the wire core on the market is divided into copper core, aluminum core, etc., among which the copper core wire has the best conductivity, and it is also a commonly used wire indoors, but the copper core wire is divided into single and multi-strand cores. Therefore, the fierce pin can be purchased according to the actual situation, and the general multi-strand copper core wire is a flexible wire, which is mainly used in the threading pipe.

2. Wires with strong load capacity.

Secondly, when choosing copper wire, pay attention to the load capacity of the wire. After all, the electricity consumption of the household is sometimes large and sometimes small, and when it is large, the TV, air conditioner, computer, lamp, refrigerator, etc. in the home may be turned on at the same time. If the power line is not loaded, and the weather is hot in summer, it will cause the wire to burn at a high temperature, causing a fire.

3. Good waterproof performance.

Then, when choosing copper wire, you should look at its waterproof performance. In particular, the wires buried in the wall, once the surface insulation is damaged, and water leakage, it will not only burn out the electrical appliances, but also cause fire and personnel. Therefore, it is important to choose a wire with a hard appearance and good water resistance.

4. The main line must be a thick core.

When choosing copper wires, the main line, that is, the wires between the power supply and all electrical appliances, should use thick core wires, after all, it carries the charge of each electrical appliance, and the wires of other branches can choose multi-core wires.

5. Length. Finally, when choosing a copper wire, you should look at the length of the fiber. Although there are meters on the wire, some unscrupulous businesses, in order to make greater profits, will reduce the meter mark in the middle of the wire by 10 meters, so that the length of the wire will be 10 meters less.

Summary: The above is to destroy the knowledge bureau is to introduce the relevant content of the 4 square copper wire can bring a few air conditioners and copper wire purchase skills, I hope to help friends in need, if you need to know more about relevant knowledge in the later stage, welcome to pay attention to Qeeka Home information.

Square millimeter copper wire is suitable for small household appliances, lamps, sockets and other equipment, and its rated load current is generally below 20 amperes.

The power of the air conditioner is generally expressed in the unit of "horse", of which 1 horsepower is equivalent to about 750W of power. For example, a 2 hp air conditioner usually has 1500w of power.

If you want to know how many air conditioners can be carried with 4 square copper wires, it is recommended that you consult a professional electrician or air conditioner installer.

How many air conditioners can be carried with 4 square copper wires depends on a number of factors. Here are four aspects, for each:

1.Copper wire conductivity: Copper is an excellent conductive material, and 4 square copper wires can transmit higher currents.

However, the exact amount of current that can be carried also needs to be considered by the length of the conductor and the size of the wire. If we assume that a 4 square copper wire is the right length and meets the standard wire specifications, then it should be able to carry a considerable current load.

2.Air Conditioner Power Requirements: The power requirements of an air conditioner depend on the type, model, and capacity of the air conditioner.

Different models of air conditioners have different power ratings, usually in watts (W) or kilowatts (kW). You'll need to look at the power ratings of each air conditioner and then add them up to determine the total power required.

3.Wire length and resistance: The length of the wire has an effect on the resistance, and longer wires produce higher resistance.

High resistance can lead to heat generation and loss of energy in the wires. Therefore, if the wire length is longer, you may need to choose a copper wire with a larger cross-sectional area to reduce resistance and ensure that the wire does not overheat.

Different countries and regions may have different standards. Make sure to choose a wire that meets the standards and follow the correct installation procedures to ensure that the wire is safe and reliable.

In summary, 4 square copper wires can carry a considerable current load, and the specific number of air conditioners can carry depends on factors such as the power demand of the air conditioner, the length of the wire, the resistance, and the safety standards. It is advisable to consult with a professional electrical engineer or follow applicable electrical regulations for accurate information and guidance prior to specific installation.
