How many watts does a square wire need? Let me know if you know.

Used in single-phase circuits, the voltage is generally 220 volts, and the copper wire can take 1650 watts, which is generally 1320 watts considering safety. Used in three-phase circuit, the voltage is generally 380 volts, and the power of copper wire is 2850 watts, which is basically about 2300 watts considering the safety of electricity use.

Wire refers to the wire that transmits electric energy. There are bare wires, electromagnetic wires and insulated wires. Bare wires have no insulation layer, including copper-aluminum flat wires, overhead stranded wires and various profiles.

Mainly used for outdoor overhead and indoor buses and switch boxes. Electromagnetic wire is an insulated wire that generates a magnetic field or induces a current in the magnetic field after being electrified.
