I need to know how many KVA is 800 amps at 208V

166.4 kva

Addendum:
I*E= VA/1000 = kVA (800)*(208)/1000 = 166.4 kVA

This is incorrect:


166.4 kva

Addendum:
I*E= VA/1000 = kVA (800)*(208)/1000 = 166.4 kVA


208 Volt is from a 3 phase system.

Therefore:

KVA = (I x E x 1.73) / 1000
KVA = 287.872

You don't know what a transformer is by your question posted in the Electrical Forum, and you think the wrong answer is a good answer?

SIR,

We have 1 500kva Gen Set three phase. From this Gen Set Maximum How much amps we can use?

The formula is:

KVA= I x E x 1.73/1000

To complete the calculation, the voltage is needed.
