How to calculate fla of a control panel
WebFrom our cable size calculator, the full load current of the 5.5kW motor is 10A. Cable size = 1.5 x 10 =15 A. Hence, the required cable shall able to carry minimum 15A current. Look at the Cable current rating Chart, 2.5Sqmm copper has the ability to carry 18 Amps, hence 2.5sqmm is suitable for 5.5kW/7.5HP motor. Web17 jan. 2014 · To properly de-rate your VFD to act as a phase converter for one-phase incoming power, start with your motors FLA. Multiply the motor FLA by two and select a VFD rated for twice the motor’s FLA. For example, if you have a 10 HP motor with a FLA of 28 amps, you’ll need a VFD rated more than 56 amps and around 20 HP.
