Full-load current rating IEC Starter Size NEMA starter size What is to a 230-volt line. AC is the rated current the of 4. A 30-hp, phase conductors and tnf the

Explanation / Answer

.given 20 hp

i hp= 746 watts

so total output will be == 746*20

=14920 watts

given that there is no losses in sytems so input power = output power ==14920 watts

input powerr == VI=14920

givenc volatge =500 v

so 500*I= 14920

i=14920/500

=29.84 amperes so the full load running current of motor is 29.84 ampers

comment me if any doubt
