How big a wire should be used for 9 kilowatt electrical appliances, and how many square wires should

9 kilowatt electrical equipment should be equipped with 6 square wires.

1. If it is a household use, it is a 220V single-phase electricity, and the current is about 45A when 9kW is fully opened, and it will definitely not reach this value normally, so it is enough to use a 6 square wire.

2. If it is a three-phase 380V, use 4 square copper wires, and if it is a single-phase 220V, use 10 square copper wires.

Commonly used copper core wire: 6A square power.

1 square current 6 amps wire diameter 1320 watts.

Square current 10 amps wire diameter 1980 watts.

Square current 15 amps wire diameter 3300 watts.

4 square current 24 amps wire diameter 5280 watts.

6 square current 36 amps wire diameter 7920 watts.

10 square current 60 amps wire diameter 13200 watts.

The current calculation is actually 6 8A, and now it is all calculated in 6 A.

The household voltage is 220V, now 9KW, and the current is about 41A.

In other words, the wire has to withstand a current of 41A, and the safe current that a 6 square copper wire can withstand at room temperature 35 is 39-50A, which is equivalent to a load current of about 20-25kW. In this load range, 6 square copper wires are all safe loads, and it is recommended to use 6 square ones.

If it is a 4 square international wire, it can generally cope with a current of 32A, that is to say, it can drive 7kw of electric energy, but this is a theoretical state, in practical life, we take into account that the safety performance is generally controlled within 6500qk, and if you query the electrician's manual, you will find that the maximum copper wire of 4 square wire is 8kw. It is not recommended to use 4 square.

Is it 380 volt three-phase electricity? With a 4 square power cord will do. Squared ones are also available. The air switch should be in a group of 15A.

If it is a single-phase electricity, a 6 square power cord should be used. 9000 watts divided by 220 volts is equal to amps. The air switch should also be greater than 40A.

For safety reasons, it is best to ask an electrician to install it.

6 square lines.

25 amps of air opening is best with touch protection. Because there is water.

The third floor is more correct, you don't need six squares, you can see how big the power cord introduced by the appliance itself is, generally three plus one.

With a line of six square meters.

9 kW with 6 square lines。In general, it is necessary to use the wire of the 6-level base briefing party, but this is not a certain value, and it needs to be determined according to the material and voltage value of the wire. If the 9 kilowatt device is connected to a single line voltage of 220 volts, then the maximum current value is 40 amps, but because the actual use, the circuit will be damaged, so it cannot reach 40 amps, if the aluminum wire is used, 10 square wires are needed, and if copper wires are selected, 6 square copper wires are required.

The meaning of kilowattskW stands for kilowatt and is a unit of measurement for electrical power in physics.

1kw is 1000w, which represents a thousand times the basic unit.

watts, 1kWh represents one kilowatt of electricity, that is, the amount of electrical power of one kilowatt of electrical appliances working for one hour. The definition of electrical power per watt is the amount of electrical power per second per unit time, and the electrical power p power w per unit time s. And the work done by 1 watt of electricity in 1 second is equal to 1 joule.

That is, 1 joule and 1 watt second.

9 kW 380V It is recommended to buy 6 square wires.

If the path is shorter, you can also use 4 squares. The allowable long-term current of the copper core cross-sectional area specified in the national standard is: square (5A 12A) (1100 2640W); square millimeters.

12a-20a)(2650～4500w)；square millimeters (16a, 25a) ; 4 mm² (25a, 32a); 6 square (32a 40a).

1. Try to buy brand wires, such as Feidiao, Baosheng, Nanyang, Panda, Jinbei cable, etc., and the product source cha dismantle hail jujube brand enterprises have strict requirements for their own product quality, and have a certain guarantee for the quality of products.

2. There is a certificate on the surface of the regular wire product, which indicates the product model, the size of the jujube, the name of the factory, the date of production, and the implementation standard.

License number and so on, if there is no such identification, it is very likely to be a three-no product.

It is not recommended to buy.

Six square.

If it is used in the family, it is generally a single 220V electricity, then its own current will be 45A at 9kw, and it will not reach this value normally, so it is enough to use a six-squared wire, if it is a three-phase 380V, it is necessary to use a four-squared copper wire, or a single-phase 220V, to use a ten-squared aluminum wire.

The voltage is 220V, the power is 9KW, and the rated current is I=P U=9000 220=. Conductors with a current carrying capacity equal to or greater than the cross-sectional area can be selected. Generally, you can choose a 6 square copper wire with a current carrying capacity of 48A.

If the power is 9 kilowatts and the rated voltage is 220 volts, the maximum current is 9000 watts 220 volts = 41 amps. Then you can choose 6 square twinax copper wire, and its current carrying capacity is 4741 amps. That is, 9 kilowatts of 220 volts require 6 square twinax copper wire.

A wire is a wire that transmits electrical energy. It is divided into bare wire, leased magnet wire and insulated wire. Bare wires have no insulation layer, including copper dismantling, aluminum flat wires, overhead stranded wires, and various profiles (such as profile wires, busbars, copper bars, aluminum bars, etc.).

It is mainly used for outdoor overhead and indoor busbars and switch boxes. Magnet wire is an insulated wire that generates a magnetic field when energized or induces an electric current in a magnetic field.

9 kilowatt electrical equipment should be equipped with 6 square wires, wires refer to the wires that transmit electric energy, magnet wires are insulated wires that generate magnetic fields or induce currents in the magnetic field after being energized, it is mainly used for motor and collapse hail voltage coils and other related electromagnetic equipment.

The wire is composed of one or several soft wires, and the outer layer is covered with a light and soft sheath; The cable consists of one or several insulated wrapped wires, which are surrounded by a rigid outer layer of metal or rubber with a burning sail. Cables and wires are generally composed of three parts: core, insulating skin and protective sheath.

9 kilowatts of electrical equipment should be destroyed with 6 square wires.

If it is a household use, it is a 220V single-phase electricity.

When 9kw is fully open, the current is about 45A, and it will definitely not reach this value normally, so it is enough to use a 6 square wire.

Voltage 220V, current = 9*1000 220 A.

The current carrying capacity of copper wire per square meter.

5-8 A, to use 6 square copper wire.

Hello dear, glad to answer for your answer: 1If it is a potato and a household, it is a 220V single-phase electricity, and the current is about 45A when 9kw is fully open, and it will definitely not reach this value normally, so it is enough to use a 6 square wire.

2. If it is a three-phase 380V, use 4 square copper wires, if it is a single-phase 220V, you need to use 10 square copper wires, adjust according to the actual situation, I hope mine will be helpful to you.
