1 How many watts can a 5 square line carry 1 5 square lines can carry how many watts

Square aluminum wires can withstand 3 kilowatts. Power refers to the amount of work done by an object per unit of time, i.e., power is a physical quantity that describes how fast or slow work is done. There are many variables in power, and the most important thing is to have a big premise when describing the power of the wire - it is used in a 220V circuit.

Under this premise, a square aluminum wire can withstand 3 kilowatts, and a square copper wire can withstand 5 kilowatts.

First of all, it is necessary to distinguish the material of the wire to determine the electric charge, and there are the following situations:

1. The safe ampacity of the copper wire through the square of the plastic pipe is 12A, according to the formula: the electric power is equal to the voltage multiplied by the current P=UI is 2640 watts, so the square copper wire can be less than 2640 watts of electrical appliances.

2. The concealed steel pipe is 16A, and the power is 3520 watts.

3. The PVC pipe is concealed, the current is 14A, and the power is 3000 watts.

It is a reference value for home improvement, and the longer the wire, the lower the current-carrying capacity. In addition, the temperature, laying method, installation environment, etc. will also affect the value of the current carrying value.

Electricity is a natural phenomenon that refers to a physical phenomenon created by a stationary or moving electric charge, which is a property of the repulsive force and attraction that arises between subatomic particles like electrons and protons.

Lightning in nature is an electrical phenomenon. Electromagnetic force.

It is one of the four basic interactions in nature. There are two phenomena of electron motion: Atoms that lack electrons are called positively charged.

Atoms with extra electrons are said to have a negative charge.

Electricity has developed the modern power industry and electronic technology. In real life, the mechanism of electricity gives a lot of well-known effects, such as lightning, triboelectric induction.

Electrostatic induction, electromagnetic induction, etc. People use it to make electric lights glow, drive machinery to turn, etc.

Long before there was any specific knowledge of electricity, it was known that electric fish deliver electric shocks. Ancient Egypt written as early as 4750 years ago.

Books record that these fish are called the "Nile."

is the protector of all other fish.

About 2,500 years later, the Greeks, the Romans, the Arabs.

It was only then that natural scholars and Arab physicians began to write about the power generation of fish.

How many kilowatts can a square wire carry A square aluminum wire can withstand 3 kilowatts.

Answer: The square copper core wire can withstand 5000W of power. First of all, it is necessary to distinguish the material of the wire to determine the charge, there are the following situations: 1. The safe ampacity of the copper wire through the square of the plastic pipe is 12a, according to the formula:

The electrical power is equal to the voltage multiplied by the current p=ui is 2640 watts, so a square copper wire can carry an electrical appliance less than 2640 watts. 2. The concealed steel pipe is 16A, and the power is 3520 watts. 3. The PVC pipe is concealed, the current is 14A, and the power is 3000 watts.

The general ampacity of the square wire is 21 amps, capacity, 12kw.

In general, a square aluminum wire can withstand 3 kilowatts, and a square copper wire can withstand 5 kilowatts.

Summary. Hello dear, the square copper wire can carry 1760 watts and 3300 watts.

How many watts can a square copper wire carry.

Hello dear, the square copper wire can carry 1760 watts and 3300 watts.

The current carried by the square copper wire is generally not greater than 15 amperes, and the 15 ampere current can generally only carry about 3 kilowatts of power, because the carrying capacity of the wire is generally calculated according to the cross-sectional area of the wire, and the size of the cross-sectional area of the wire determines the current through the wire, and the number of internal copper wire strands has nothing to do with it, so there is no difference between the bearing capacity of multi-strand copper wire and single-strand copper wire, so the wattage of the square copper wire is about 3 kilowatts.

The material of the wire affects the electric charge: the copper wire passes through the plastic pipe: the square safe current carrying capacity is 12A, according to the formula: the electric power is equal to the voltage multiplied by the current P=UI is 2640 watts, so the square copper wire can carry less than 2640 watts of electrical appliances.

The most in the home should be lighting, and more here refers to a large number. Now when decorating, they like to install downlights, and the number of downlights is large, but it is not very powerful. If we estimate, generally speaking, the maximum electricity used for lighting at home is 500 watts, so there is no problem with using 1 square or square copper wire.

Flat copper wire can carry electrical appliances of about 3kw.

If the power cord is a copper core wire, the maximum allowable working current of the open wire installation is 20A, that is, 4400 watts, the concealed steel pipe is 16A, the power is 3520 watts, and the PVC pipe is concealed, the current is 14A, then the power is 3000 watts.

Moreover, every 1 square millimeter cross-sectional copper core wire, if used in a 220V single-phase circuit, can safely carry the current passed by a load of 1kW, and if used in a three-phase balanced load (such as a motor) circuit, it can safely carry the current passed by the load.

Precautions for the use of wires.

The wire is divided into a single pattern, a filamentous pattern, or something in between, consisting of a few slightly thicker cores. The single one is mainly used for the main circuit layout of the home circuit, and the single wire is not easy to twist, and the wiring such as the terminal of the bulb or the terminal of the socket is inconvenient. The filamentous one is softer and suitable for small electrical appliances.

It depends on the composition of several thicker cores, but which one is mainly used as a home wiring circuit.

The toughness of the metal core, the metallurgical quality of the metal is different, and the toughness is also different. For the metal core, you can twist a few times to see if it is easy to twist, and for the wire of the copper wire, you must see whether the copper wire is too thin, too fine must be difficult to even, and it is easy to break after a long time.

When the power supply is single-phase AC 220V, the square copper wire can withstand about one kilowatt.

Power = voltage x current, according to this calculation, the square copper wire can withstand about 2---3 kilowatts.

The load capacity of a wire is measured in terms of current carrying capacity. Because the conductor has resistance, the current generates heat through the resistance: the smaller the wire cross-section, the greater the resistance per unit length, and the greater the heat generation.

The safe ampacity of copper conductors is determined by the allowable maximum core temperature, heat dissipation conditions and laying conditions, so there is no uniform formula to calculate. According to the experience data of the industry, usually the square copper core wire allows the long-term load current of 8A--15A, when the heat dissipation conditions are unfavorable, the lower limit data can be selected, and the upper limit can be selected for open or overhead laying.

A single wire can take a higher current carrying capacity than multiple parallel wires; The current carrying capacity of the open wire laying is higher than that of the wire laid through the pipe.
