Is the full load current rating of a 3 phase motor referring to amps per phase?

NO, ONLY ONE. If you are measuring line current. The purpose of the line to line measurement is to know if your load is drawing balance ampere and slight difference is negligle.

How do you make correct setting for overload of a 3 phase motor?
125 percent of full current rating of the motor
What is the cable size for 600V 3 phase ac motor?
you need the current of motor or the KW/HP rating
What motor gets more heated single phase or three phase?
Your question is a little like asking, 'How long is a piece of string?'! Do the two motors have the same power rating, or are they different?The rate at which energy is used by any machine is defined by its power rating. If the power ratings of two different machines are the same, then both machines use energy at the same rate. So if a single-phase motor has the same power rating as a three-phase motor, then they will both use exactly the same amount of energy over a given period of time.So, if a single-phase motor has a greater power rating than a three-phase motor, then the single-phase motor will the greater amount of energy in a given period. On the other hand, if a three-phase motor has a greater power rating than a single-phase motor, then the three-phase motor will the greater amount of energy in a given period.
Will a 208 volt 3 phase generator supply operate a 230 volt 3 phase motor?
Yes, but the motor's horsepower rating will not be reached.
What is the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?
If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.

How do you calculate the no-load current of a three phase induction motor?
All transformers, single phase or three phase have a "no-load current" rating. That is simply the nameplate rating of the Xformer in VA, (volt-amps) or KVA (1000Volt-amps) for larger Xformers. Simply divide the nameplate rating in VA or KVA by the supply voltage and you'll get the Xformers potential maximum output in ampheres.
What size feeder and breaker is needed for a 15 ton AC - 3 phase at 440 Volts?
Would have to know the current rating of the motor or each of the phases on the motor when running. 3 Phase motors usually use mucvh less current than their single phase counterparts. My son has a lot of 3 phase equipment in his shop and most of them run under 5 amps per leg. But you really need those specs from the motor.

How does the 3-phase induction motor acts like 2-phase induction motor if a phase is disconnected from supply?
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
What you basically want is will each phase take 26 Amps current for 15HP 3 phase 415VAC motor?
Yes. In a 3-phase motor, all 3 phases have the same current.
What will the current be on a hand held meter on a three phase motor if you clamp to two leads?
No way to tell. first off odds are you're measuring voltage rather than current, but apart from that the value would differ with your grid service and the rating of the motor
How many percent will be the starting current for motor?
Motor starting current is typically 5-7 times the rated current of the motor. (For three phase induction motors)
What should be the current of siemens 75 kw motor at no load?
starting current of 3 phase 75 KW induction motor
