WebbFor calculating the size of any cable, you have to get through some steps. First Step is to determine the specification of your electric load: Voltage (V): Specify the supply voltage and select the phase arrangement: 1 Phase AC or 3-phase AC. Load (kW, kVA, A, hp.): Specify the load in kW, kVA, A, or hp. In addition, you have to specify cos {Φ ...
