6 square wires are the main power line, and the other 2.5 square wires are used as branches.

Air conditioning is a more complex structure of household appliances, and the power of air conditioning is generally relatively large, the demand for electricity is very high, so the air conditioning must choose the right wire to connect; The current of household air conditioning is generally about 5A, so the household air conditioning wire with 1.5 square can be used, but if it is a high-power air conditioning, the current is greater than 10A, you need to use 2-4 square wires, the air conditioning wire must choose the right one, otherwise the air conditioning can not operate normally;

Air conditioning cable 2.5 square is enough. 2.5 square wires can pass 28A current, carrying current power is 6000W, and the air conditioner cabinet is more than 1000 watts, and the bath is 2000W, so it is recommended to use 2.5 square wires, safety is enough.
This depends on the power of the vertical air conditioner to determine the wire diameter.
Take a 3-piece air conditioner as an example.
Rated current of 3-piece air conditioner =735*3*220*0.85=11.79 (ampere).
According to the normal overflow of copper wire per square millimeter 6 amps, 3 air conditioners should choose to use 2.5 square millimeters of copper wire.
Vertical air conditioning wires need to be placed on an area of at least two square meters.
Because the installation of vertical air conditioners requires connecting the power supply, enough space should be reserved to ensure the safe and stable connection of the wires.
At the same time, this area can also facilitate maintenance and replacement of wires.
In the actual installation process, if you encounter the need to place the wire space is small, you can consider extending the wire, but to ensure that the installation of the wire meets the relevant safety standards.
Vertical air conditioning is related to several P, such as the input power of the 5-piece machine is about 4800 watts, the working current under 220 volts single-phase electricity is 22 a, requiring 6 square millimeters of line, if it is three-phase power, each phase is not less than 1.5 square lines is enough. Copper wire 2.5 square, aluminum wire is a new wire connector not too much then 4 square is enough, but the premise is that the voltage should be stable, not low. Generally, a square copper wire can withstand 5A current, and the rated current of the air conditioner with 3300W cooling capacity is about 6-7A, which is enough to use.
According to the wire voltage and current size, the indoor installation of vertical air conditioning wires should meet the following requirements:
< br >
1. Set in the fire, moisture, corrosion and other special requirements of the cable tray;
< br >
2. Cables with rated voltage 300\/500V and below are allowed to be buried in beams, plates and walls of reinforced concrete structures, but the depth of the buried layer should not be less than the thickness of the concrete protective layer, and not less than 20mm;
< br >
3. All cables in the building should meet the local fire protection requirements and take adequate fire prevention measures;

four
Depending on how much power your air conditioning is, if 2 or 3 pieces are generally more than 4 flat enough, if it is 5 pieces, it is best to use more than 6 flat...
