It would be good to know the reason why it's multiplied by specific value.....

Have you video on machine safety relays and safety plc

[@michaelcostello6991]

I assume the current calculated here is for full load. If the motor is not fully loaded the current would be significantly lees amps

22.75

Thank you sir. Is efficiency of motor not important in the calculation??

[@TheElectricalGuy]

For interview purposes it's not necessary to add efficiency

[@sathyasathya5110]

13kw = 22.6A

[@manuellastrollo2168]

your formula in finding current for horsepower need %Eff on your formula that is I=Hp x 746/E x %Eff x Pf x √3

[@TheElectricalGuy]

For interview purposes you don't need to add efficiency in calculation
