To calculate the cross-section of the supply cable used in the three-phase network, you must use the following formula.
To provide one-tap water heated by water, a device with a capacity of 3 kW will be required, and if a 12 kW or higher heater is installed,the connection must be made to a three-phase network.
That is, if the phase conductor is connected to the phase“B” of the three-phase network, then it should have a green color.
Professional inverters are designed for current consumption of 220/380 V,often from a three-phase network of electric current.
Distinctive feature of selecting the cable cross-sectional area for use in the three-phase network is that the thinner core can withstand a greater load.
This method applies only to the device, which is planned to be connected to a three-phase network with a voltage of 380/220 V.
