How much can the aluminum wire run in 6 square meters

The current carrying capacity of the wire 6 square aluminum wire is 42a.

The current carrying capacity of 6 square aluminum wire is 7 times that of its cross-section, i.e. 6x7 = 42a.

The safe ampacities of aluminum cables are:

Multiply by nine at 2.5 and subtract one by one straight up.

Thirty-five times 3.5, double in a group minus five.

The conditions have been changed and converted, and the high-temperature nine-fold copper has been upgraded.

The number of pipe roots is two, three, four, eight, seven and six folds full of load current.

The first sentence of the formula means: the current carrying capacity of aluminum core insulated wires of various cross-sections of square and below is 9 times the number of cross-sections. If a square wire is squared, the current carrying capacity is .

The relationship between the current carrying capacity and the number of cross-sections of the conductor of 4 square and above is to go up along the wire number, and the multiple is subtracted by 1 one by one, that is, 4.

The second sentence of the formula means: the current carrying capacity of a wire of 35 square is a multiple of the number of cross-sections, that is, 35. From 50 square and above wire, the multiple relationship between its current carrying capacity and the number of cross-sections becomes two two wire numbers into a group, and the multiples are subtracted by 0 5 in turn, that is, the current carrying capacity of the square wire is 3 times the number of cross-sections, the current carrying capacity of the square wire is the multiple of its cross-sectional area, and so on.

The third sentence of the formula means: the conditions applicable to the formula are "aluminum core insulated wire, single open dressing, ambient temperature 25". If the aluminum core insulated wire is laid in an area where the ambient temperature is higher than 25 for a long time, the current carrying capacity of the wire can be calculated according to the above formula, and then it can be discounted.

When using not aluminum wire but copper core insulated wire, its current carrying capacity is slightly larger than that of aluminum wire of the same specification, and the current carrying capacity of one wire number can be calculated according to the above formula method. For example, the current carrying capacity of 16 square copper wire can be calculated according to the current carrying capacity of 25 square aluminum wire.

The fourth sentence of the formula means: in the case of laying two, three, or four wires through the pipe, the current carrying capacity is calculated as % of the current carrying capacity (single laying) in the formula.

6 square aluminum wire is about 20A current, and 15kw electric heater needs about 30A current. Therefore, 6 square aluminum wire is not allowed, it will be very dangerous. You can use 6 flat copper wires or 10 flat aluminum wires.

6 square copper wires can withstand kilowatts. The maximum ampacity of 6 square is 50a, due to the consideration of factors such as pipe penetration, buried wall and ambient temperature, the maximum safe current carrying capacity is 50*, then the maximum power that 6 square copper wire can withstand is 220*40=8800w.

Usually in a 220-volt circuit, a 6-squared copper wire can carry kilowatts, but if in a 380-volt circuit, a 6-squared copper wire can carry 13 kilowatts. Specifically, according to the wire laying method, casing material, etc., when selecting wires, try to choose a large diameter to avoid overload operation.

1 square wire load wattage calculation.

An empirical formula commonly used by electricians: as long as it is a copper core wire, the cross-sectional area of each square millimeter can safely pass through the rated current of 4-5A; In a 220V single-phase circuit, the current is about about 1KW of power; In a 380V three-phase balanced circuit, the current is about 2A per 1kW of power.

The above values can be calculated by physical calculation formulas, and the results are very close, so electricians can memorize these in order not to memorize those cumbersome calculation formulas in their work. Then according to this algorithm, it is known that every 1 square millimeter cross-sectional area of copper core wire, if used in a 220V single-phase circuit, can safely carry the current passed by a load of 1KW; If it is used in a three-phase balanced load (e.g. electric motor) circuit, the current through the load can be safely carried through.

6 square copper wire 40 amp, aluminum wire 30 a, can operate safely.

The amount of copper wire passing through 6 square is 48A, and the current of 220V can drive 220W with a current of 1A Pei, and the voltage of 380V with 1A Pei can drive 380W of electrical equipment.

In electromagnetism, the amount of electricity passing through any cross-section of a conductor per unit of time is called current intensity, referred to as current, the current symbol is i, and the unit is ampere (a), referred to as "ampere".

André Marie Ampère (1775 1836), French physicist and chemist, was distinguished by his research on electromagnetism, as well as his contributions to mathematics and physics. The SI unit of electric current is named after its surname).

The free charge in the conductor moves regularly and directionally under the action of the electric field force to form an electric current.

Electrically stipulated: the direction of the directional flow of positive charge is the direction of the current.

In addition, in the project, the directional flow direction of the positive charge is also the current direction, and the magnitude of the current is expressed by the charge Q flowing through the conductor section per unit time, which is called the current intensity.

Nature has many kinds of carriers that carry electric charges.

For example: electrons that can be moved in a conductor, ions in an electrolyte, electrons and ions in a plasma, quarks in hadrons. The movement of these carriers forms an electric current.

A 6 square copper wire can withstand a current of 50A.

If it is a 6 square copper wire, it can withstand the current of 50A, and the load is generally 11000W when it is used for 220V, and the load is generally 19000W when it is used for 380V. If it is a 6 square aluminum wire, it can withstand the current of 30A, and the load is generally 6600W when it is used for 220V, and the load is generally 11400W when it is used for 380V.

In electromagnetism, the amount of electricity that passes through any cross-section of the conductor per unit time is called current intensity, referred to as current, and the current symbol is i, and the unit is amperes, referred to as amperes. Electrically, it is specified that the direction of the directional flow of positive charge is the direction of current, and in addition, the direction of directional flow of positive charge is also used as the direction of current in engineering.

Measuring Current Instruments:

1. Clamp table.

Clamp ammeter is an instrument that integrates a current transformer and an ammeter, and its working principle is the same as that of a current transformer. The clamp meter is a combination of a current transformer and an ammeter, the core of the current transformer can be opened when the wrench is pinched, and the wire through which the measured current passes can pass through the gap of the core without being cut off, and the core is closed when the wrench is released.

2. An ammeter.

When wiring the DC ammeter, attention should be paid to its positive and negative polarity, the positive terminal of the ammeter is connected to the direction of the actual current, and the negative terminal of the ammeter is connected to the direction of the actual current flow. First, adjust the pointer of the ammeter to the 0 position, connect the ammeter line post to the positive pole of the dry battery Shenghui, and connect the negative terminal post of the ammeter to the 5A terminal post with the maximum energy.

9a。Reason:

The current carrying capacity of a square aluminum wire is 9 times that of its cross-section, that is, a square aluminum wire can pass 9A current.

Aluminum: Silvery-white light metal. Malleable.

How many square copper wires is 6 square aluminum core wires equivalent to? How many kilowatts can it withstand?

6 square aluminum core wire is equivalent to 4 square copper core wire, which can bear 30A current, which is equivalent to a kilowatt of single-phase 220V with a trouser car, and a kilowatt of 380V single-phase with Shenfeng; Three-phase 380 220V can be connected with kilowatts.

Dear, hello, I am glad to answer for you: what is the current that can be passed by each square aluminum wire? A:

The current that a square aluminum wire can withstand is 5A, that is, 1100 watts, and the current that a square copper wire can withstand is, that is, 1600 watts, but the actual need to be decided according to the installation method, temperature and use environment of the local Zen wire, and see whether the wire is installed as a bright wire or a dark wire, the heat dissipation effect of the bright wire is better than that of the dark wire, so the maximum safe current of the wire is relatively larger. I hope mine can help you, I wish you a happy life, if I'm helpful to you, please give me a 5-star thumbs up, thank you for your support to me.

Answer: Find a practical hardware manual, the safe working current per square of aluminum core wire is, and the current that the square aluminum wire can withstand is.

Extension: The rated current of the cable in the circuit is also related to the line frame (laying) mode, such as the rated current that the overhead line electric bench shed cable and the buried line cable can withstand is different, but the rated current size change caused by the different line frame (laying) methods, the relative cable material, wire diameter and the size of the rated current change, the proportion is very small, and it is often ignored. According to the three-phase electric power formula:

p= 3*u*i*cos or single car positive phase electric power formula: p=u*i, although its rated safe working current is certain, but the specific load power is also related to the power supply voltage. The influence of the line distance on the voltage (line voltage drop) is 500 meters, the line distance should be kept within 500 meters, the voltage drop of the line is ignored, and the load power is not affected by default.

30 ampsIn general, the current that 1 square aluminum wire can withstand is about 5 amps, so it can be concluded that the current that 6 square meters can withstand is 30 amps.
