use 1.0 as your PF Understand that K=1000, so KVA simply means thousands of volts times amps. First, multiply KVA by 1000 to get VA, then divide by the voltage of the system to get amps. Example: 6KVA, 240V single-phase. 6 * 1000 = 6000 VA 6000 / 240 = 25A
amps X volts / 1000 = Kva (for a single-phase system).
Kva stands for Kilo-volt-amperes, and the Kilo- prefix means thousands.
Also, Kva X Power Factor = Kw
Example:
120 volt, single-phase load drawing 10 amperes with a power factor of 0.8 (80%) draws how many Kva and how many Kw?
120 X 10 / 1000 = 1.2 Kva
1.2 X 0.8 = 0.96 Kw
50 Amps Single Phase 20 Amps Three Phase
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
You must rephrase your question to make it more specific. <<>> The formula to use to find KVA in a three phase system is, KVA = Amps x Volts x 1.73/1000.
Va=volts x amps. The K stands for one thousand. So 1 Kva is one thousand watts. So 415v times 120a= 49,800 what's. You divide that by a thousand and you get 49.8. So it would be 49.8 Kva.
To answer this question a voltage needs to be stated and whether the load is three phase or single phase. Without the voltage the amperage can not be calculated. For single phase, Amps = kva x 1000/voltage, for three phase, Amps = kva x 1000/1.73 x voltage.
Single-phase, 2.5 amps; three-phase 1.443 amps.
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.

Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.

A kw (kilowatt) is 1000 amps x volts. If you assume your one phase system has 120 volts, then divide by 120. Cheap, but close enough for most work, assume 100 volts, then each amp is a tenth of a kilowatt.
In the U.S. single phase at 200 amps is average.
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
That load would be 10.9 amps.
