How to wire the three bedrooms with an air conditioner?

Pull three wires to supply power to three air conditioners, and then connect the lighting, sockets and other electrical equipment in each room. Because air conditioners are high-power appliances, it is necessary to pull three wires to supply power to three air conditioners. When wiring, don't put it together with the power supply lines such as lighting and TV sets, but run it separately from the lighting, sockets and other electrical equipment in each room to avoid adverse effects such as series connection and short circuit. It is best to use copper wire instead of aluminum wire for air conditioning lines. Thick copper wire is suitable for large equipment, such as large outdoor units and indoor extensions. Household air conditioning, generally 4 square lines.
