It depends on (1) its voltage rating, and (2) whether it is single phase or three phase. And the symbol for kilovolt ampere is kV.A -not 'kva'.

Are motor conductors sized to the locked rotor current?
According to 2011 nfpa 70 nec Motor conductors are sized with the flc- full load current or the nameplate rating fla- full load amperes
What is the Full load motor current of a 75KW motor?
Full load starting current is typically in the region of 5or 6 times the full load motor current;.
What is full load-current in primary?
This is the current flowing in the primary circuit when full-load current flows in the secondary circuit.
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 is a full load current in single phase transformer?
It is the rated maximum current that can be taken from the transformer. This is equal to the VA rating divided by the output voltage. So a 6 kVA 240 v transformer would have a maximum current rating of 6000/240 or 25 amps.
How do you calculate the fuse rating level if the full load is 4 amp?
A fuse rating is normally the 120% of the rated full load current. So, 4 amps times 120% is (4x120%) = 4.8amps
Are motor conductors sized to the locked rotor current?
According to 2011 nfpa 70 nec Motor conductors are sized with the flc- full load current or the nameplate rating fla- full load amperes
What is the percentage of the no-load current in a transformer to its full load current?
2 to 5% of full load current
How we decide the rating and requirement of CBCT?
Generally we use CBCT for earth fault/earth leakage relay tripping. Since the CBCT is going to provide on neutral side, first we have to find the full load current. If the full load current is 500A we have to use 100A/5A (ie 1/5th of full load current) CBCT. arunarafa@gmail.com

In general a controller used to start and stop a motor shall have a rating equivalent to?
twice the full-load current. code 430.83(c)
What is the starting current value compared to full load current?
The starting current of any electrical equipment which is 6 times more than that of the full load current. ex: full load current = 5 A the starting current will be 5*6 = 30 A.
What will happen if i connect a power supply of higher current rating to lower current load?
The supply won't have to work as hard. It is perfectly acceptable, for example, to use a 1A, 12v supply to supply a 12v, .5A load. The current rating indicates the ability of the supply to dissipate heat caused by the current flowing. If the load current is above the power supply current rating, the power supply will overheat.
What is a full load current in single phase transformer?
It is the rated maximum current that can be taken from the transformer. This is equal to the VA rating divided by the output voltage. So a 6 kVA 240 v transformer would have a maximum current rating of 6000/240 or 25 amps.
What is full load magnetising current of transformer?
is it primary current ?
