7.5kVA is a value derived from the voltage multiplied by the current.Without knowing one, you cannot know the other.For example, think of the number 10kVAThis could be made by :10kV * 1A or 5kV * 2A...
There is appoximately zero kVA in 14amp, .5 volt AC.
8,000 watts = 8 kVA / (the power factor) If the power factor is 1, then 8 kVa = 8,000 watts.
