The wire live wire is red, and the neutral wire can be selected in several colors: red, yellow, blue, green, brown, white, black, and two-color. Single-core wire, squared wire, for lighting, single-core wire, squared wire, for sockets.

Single-core wire 4 square wire is used for more than 3 horsepower air conditioner, single-core wire 6 square wire is used for total incoming wire, and two-color wire is used for grounding wire. The two-core and three-core sheathed wires are used as open wires, which are mostly used for construction on the construction site, and are not used for home decoration. The three-core sheathed wire square can be used for cabinet air conditioners.

The general specifications are: 1, 1, 5, 2, 5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, etc., and the cross-sectional area of the wire is equal to the square of the radius of the multiplied wire.

In practice, it is much more complicated than expressing the value of the bridge. In addition to the diameter of the wire, the safety current and safety power are also related to the quality of the copper wire and the external temperature. When users and friends buy power cords, they must look for the national standard copper wire.

**The data in this is a theoretical value at 25 degrees Celsius, and the operating temperature may be higher than this. Therefore, it is recommended that users choose a larger power cord.

The power corresponding to the square of the copper wire is calculated according to the current, which is divided into the following algorithms:

1. The current carrying capacity of the wire can be obtained by looking up the meter, which is convenient and intuitive.

2. Multiply the estimation method by nine by 2.5 and subtract one by one 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 square of the wire and the power of the square copper wire can accommodate 2200W, and the square plastic copper wire can hold 3500W.

The 4 square plastic copper wire can accommodate 5200W, the 6 square plastic copper wire can accommodate 8800W, and the 10 square plastic copper wire can hold 14000W. There is no direct mathematical relationship between the square of the wire and the power. The square of a wire usually refers to the cross-sectional area of the wire, which is used to describe the thickness or conductivity of the wire.

Whereas, power refers to the rate at which electrical energy is converted into other forms of energy in a circuit, and the unit is watts (W).

The cross-sectional area of a wire is related to power, but it is not a direct mathematical relationship. The larger cross-sectional area can accommodate larger currents and therefore higher power can be transmitted. In general, the use of wires with a larger cross-sectional area can carry higher power currents, reducing the problem of wire heat generation and voltage drop.

The magnitude of the power depends on the product of voltage and current, i.e., power = voltage and current. In a circuit, voltage and current can be determined by different electrical devices, loads, or power sources.

It is important to note that the use of appropriate wire cross-sectional area is to ensure that the wire can withstand the current and power transmitted to avoid wire overload and safety hazards. In practice, the appropriate wire cross-sectional area should be selected according to the specific power demand, current load, and characteristics of the wire.

Select the rounding of the wire

1. Current load: determine the rated current of the wire according to the actual needs. The load current and possible overload currents in the circuit are considered to ensure that the wire can withstand the required current and avoid overheating or short circuiting the wire due to overload.

2. Ambient temperature: The rated current of the wire is related to the ambient temperature. In a high-temperature environment, the heat dissipation capacity of the wire will be weakened, so it is necessary to select the appropriate wire current rating according to the ambient temperature to ensure the safe operation of the wire.

3. Wire material and cross-sectional area: Wires of different materials and cross-sectional area have different rated current capabilities. Depending on the material and cross-sectional area of the wire, the appropriate current rating is selected to meet the needs of the circuit and ensure that the wire will not be damaged by overload.

4. Voltage level: select the appropriate wire rated current according to the voltage level of the circuit. Different voltage levels correspond to different insulation materials and insulation thicknesses to ensure the safe operation of the circuit.

5. Standards and specifications: select wires that meet national or industry standards, and select them according to the rated current value given in the standards to ensure that the quality and performance of the wires meet the requirements and can meet the safety and reliability requirements.
