How many amps can 1 square copper wire withstand, and how many kilowatts can 1 square copper core wi

1. 1 square copper wire can withstand a current of 6 amps.

1. One square meter of aluminum core cable can withstand the current of 3A-5A.

2. Amperes of current that copper wire can withstand.

The number is related to the length of the cable, the form of line laying, and the ambient temperature of the cable. indoors, 6 square millimeters.

The following copper wires, under normal circumstances, are safe with a current of no more than 10A per square.

3. Press"Electrician empirical algorithms"to estimate:

1) Because the cross-sectional area of the copper core wire per square millimeter is about the rated current that can be passed.

In the single-phase 220V line, the current per 1kW is about three-phase (including three-phase four-wire system).

In the three-phase circuit, the current per 1kW power is about 2A, so it can be used.

4. Cables.

Ampacity per square meter.

There are two ways to determine:

1) Check the table method: check the corresponding cable safety ampacity comparison table (as shown in the table below), which can be obtained directly. For example, if a 10 square aluminum wire has a safe current carrying capacity of 53A (triangular arrangement) or 71A (straight arrangement), the average value.

For example, if 10 square aluminum wire is calculated, the safe current carrying capacity is 6 times that of its cross-section, that is, 10x6=60a, which is similar to the above table lookup results.

It can withstand a maximum current of 15 amps, and generally matches the electrical power of about 13 amps.

In a single-phase circuit, it is typically 1320 watts. In a three-phase circuit, it is around 2300 watts.

1. According to the current carrying capacity of 1 square copper wire, it can be known that its safe current is ampere, if it is used in single-phase circuits, that is, household electricity, it is generally 220 volts, and the calculation formula of power can be substituted for 1 square copper wire can be 1650 watts, but considering the safety, generally speaking, it cannot reach such a high level, and can only be calculated according to the coefficient, so it is generally 1320 watts.

2. If it is used in a three-phase circuit, the voltage is 380 volts, and the calculation formula of the same substitute power can be obtained, the power of 1 square copper wire is 2850 watts, but considering the safety of electricity, generally speaking, it cannot be so high, basically about 2300 watts.

Power of different wires:

Generally speaking, there are 1 square copper wire, as well as square, square, 4 square and 6 square and 10 square wires, and different wires, its current carrying capacity is different, and the power is completely different

1. The square copper wire, its current carrying capacity is between 8 A and 15 A, so the power is about 3 kilowatts, that is, if the electrical appliances in the home are within the range of 3 kilowatts, the square copper wire can be installed.

2. The safe current carrying capacity of the square copper wire is 16 A to 25 A, and the power of this copper wire can be calculated to be about 5 kilowatts. Generally speaking, it is suitable for lighting or socket connections.

Square copper wire, its safe current carrying capacity is 25 A to 32 A, the power is about 7 kilowatts, some power appliances can lay 4 square copper wire.

The square copper wire has a current carrying capacity of 32 amps to 40 amps, and the power can reach kilowatts.

The safe current carrying capacity of the square copper wire is 60 A to 70 A, and the power is relatively large, capable of reaching 15 kilowatts.

1 square copper wire can withstand currents between 5 amps and 10 amps. The specific amount of current that can be withstood generally depends on the actual length of the copper wire and the actual installation environment. If the length of the copper wire is very long and the temperature of the installation environment is very high, the current value that can be withstood by 1 square copper wire will be affected, and the maximum current can only be 5 amps.

If the length of the copper wire is very short and the temperature of the installation environment is very low, then the current value that 1 square copper wire can withstand is about 10 amperes.

Arrange the wires correctly when decorating the house1. When arranging wires in the house, reasonable arrangements should be made according to the different power of electrical appliances and circuits. If you want to use a wire as a main lighting line, you should choose to use a flat wire, and if you want to use a wire as a general lighting line, you can choose to use a flat wire.

2. When arranging sockets in the bedroom and living room, you should generally choose to use flat wires for wiring. The sockets of air conditioners, refrigerators, water heaters and other electrical appliances need to be wired with 4 flat wires, because the power of these electrical appliances is relatively large, so they generally need to be equipped with a separate socket, and 4 flat wires need to be used for wiring.

3 to 7 kilowatts.

If it is a single-phase voltage, the power of 1 square copper core wire is about 3kw, and the publicity is as follows: power p=. The three-phase voltage, the power of 1 square copper core wire is about 7kw, and the publicity is as follows: power p=.

Generally speaking, there are 1 square copper wire, as well as square, square, 4 square and 6 square and 10 square wires, and different wires, its current carrying capacity is different, and the power is completely different

Characteristics of copper core wire

Copper cores are subjected to a higher load. I believe we all know that in the past, when wiring at home, everyone commonly used aluminum core wire. With the increase of household electricity consumption, the load that the wire needs to bear is also rising, and the aluminum core wire can no longer meet the demand for electricity consumption, so the copper core wire has gradually entered the historical stage.

Secondly, the copper core wire, its internal resistance is small, the current carrying capacity is large, to prevent the loss and waste of electric energy, and the copper core has a long service life and good anti-corrosion effect, so compared with the aluminum core wire is loved by people.

Under normal voltage, 1 square copper can withstand the current, which is about 1600 watts.

The bearing capacity of the wire is also different for different voltages, for example, 220W can drive kilowatts per square millimeter, and 380W can withstand kilowatts. The electricity consumption of home lighting is not large, and all the things in the house will not add up to 500, even if it is a relatively large chandelier, it will not exceed 1000w, and all can be directly squared wires.

Home improvement wire purchase:

1. Look at the sign on the surface of the wire, according to the relevant national regulations, the surface of the wire must be marked with the manufacturer, model and rated voltage of the product.

2. Look at the inner core and appearance, the high-quality wire is flat and smooth, the skin insulation protective layer is not worn, the handwriting should be clear, and there is no greasy feeling when touched. In terms of cross-section, the thickness of the insulation layer should be uniform and the inner core should be centered.

One square millimeter of copper wire can withstand a current of 5A for a long time.

Press"Electrician empirical algorithms"To estimate: because the copper core wire is about the rated current per square millimeter cross-sectional area, and in the single-phase 220V line, the current per 1KW is about, and in the three-phase (including three-phase four-wire three-phase system) circuit, the current per 1KW power is about 2A, so it can be used, if it is a single-phase circuit, the wire required for each 1KW power is basically 1 square millimeter, and in the three-phase circuit, every 1 square millimeter of copper wire can pass through the current of about power.

Do the math how much it will cost you to renovate your home

1 square wire is more common in home decoration life, and it can meet the wiring needs of lighting. So how much current can a 1 square wire withstand? Let's find out with me!

How much current can 1 square copper wire withstand.

1 square copper wire can withstand 6 amps.

The amperage of current that a copper wire can withstand is related to the length of the cable, the way the line is buried, and the ambient temperature of the cable. Indoors, copper wires within 6 square millimeters are generally safe with a current of no more than 10 amperes per square meter.

Different wires are subjected to different loads.

1. There is 1 square copper wire, and there are square ones, generally speaking, its working current can reach 20 A, and if it is installed with open wires, the power can reach 4400 watts. The choice of the destruction of the bureau is the concealed installation method, the current will be relatively smaller, the big pin is 16 amps, and the power is about 3520 watts.

2. Some people will choose PVC sleeve for the wire, and then install it, this current will be smaller, mainly combined with the laying environment, its heat dissipation function will be worse, generally speaking, the current value is allowed to pass through 14 A, and the power is about 3000 watts.

3. Some will choose a square wire, which has a current between 16 A and 25 A, so the current load can reach 5500 watts.

Square wires are also more common, some electrical appliances with relatively large power will choose 4 square wires, and the current carrying capacity will be larger, which can reach 30 36 A, so the electrical load that can be borne will also be relatively large, such as the maximum can reach 6 8 kilowatts.

5. If you choose a 6 square wire, the power will be greater, because its current can reach 63 A, so it can load 10 kilowatts of electrical appliances.
