The formula you are looking for is volts x amps divided by 1000.
Yes of course!! 10 kva electrical power is 10 kva electrical power either it would be three phase or single phase. But other factors i.e. current, voltage changes accordingly. Actually this question is quit confusable. Because in 3phase system, if each phase gives 10kva power (single phase power = 10 kva) then 3 phase power will be 10 X 3 = 30 Kva If we go leteratualy towasrds the question, then the asnwer will be - No. becasue 10 kva supply to 3 phase load will be 3phase supply(i.e440V) & 10kva supply to single phase load will be single supply (i.e 250V).
It's because the voltage is a specified value, and the current drawn has a limiting value. So multiplying those together gives the VA or kVA that it can supply.
1.035 KVA
A two pole breaker protects both L1 and L2 legs. An over current on either leg will trip the breaker.
The voltage and current will give the kVA, but the kW depends on the power factor of whatever load is connected to the supply. For a (let's say) 11 kV supply, the voltage from line to neutral is 11,000/sqrt(3) which is 6351 v. The kVA on each phase is 6.351 times the current, and you just add up the three kVA values to find the total. At higher voltges like 11 kV the three currents in the lines are usually very nearly equal.
A 6kw load on a 240volt circuit is 25amps.

12HP is approximately 10.8 KVA. You would want to use a 15KVA transformer to supply this motor. KW = HP * .75 KVA = KW * 1.2 (These formulas are approximate)
You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.
It's because the voltage is a specified value, and the current drawn has a limiting value. So multiplying those together gives the VA or kVA that it can supply.
62.5 amps
An ordinary PC has a 300-500 watt power supply. 16 of them would draw 8 kW maximum, and allow 25% extra for peripherals, so that's 10 kW, so a 45 kVA supply would be fine.
100amp
The values you state are two different values. KVA is the value of voltage times amperage times 1000. The voltage value of 240 volts is just 240 volts. If you have an amperage it can be applied to the first equation to find the KVA value.
There are zero amp into or in 240 volts. These are two different entities. A load needs to be connected to the 240 volt supply and then the amps will flow in relationship to the resistance of the load.
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
P=1.73xVxIxCOSO KVA=KW/1.73xCOSO KVA=2000/1.4 KVA=1.42
