Single-phase, 2.5 amps; three-phase 1.443 amps.
To calculate the amperage for a 10kW heater on a 3-phase 220V system, use the formula: Amps = (kW x 1000) / (√3 x Volts). So, Amps = (10 x 1000) / (√3 x 220) = 26.18 amps per phase. Therefore, the total current drawn by the heater is 26.18 amps per phase multiplied by 3, which equals approximately 78.54 amps.
To convert from kilowatts (kW) to amps in a 3-phase system, we need to know the system voltage. Using the formula: Amps = (kW x 1000) / (√3 x Volts), where √3 is the square root of 3. Assuming a system voltage of 120/208V, the amperage would be approximately 135.1 amps.
To convert from kilowatts (kW) to amps in a 3-phase system, you can use the formula: Amps = (kW × 1000) / (√3 × volts). In this case, with 42 kW and a voltage of 120208 V, the amperage would be around 139 amps.
In a three-phase 225 amp panelboard, each phase will carry 225 amps. This means that the total current flowing through the panelboard is distributed evenly across the three phases, allowing for a maximum of 225 amps on each phase at a time.
In a standard 3 phase system in North America, 7kVa would be equivalent to 19.5 amps on each phase. The equation is: 7kva*1000/208v/1.73=19.45 amps (3 phase)
Single-phase, 2.5 amps; three-phase 1.443 amps.
If all three legs of the system are balanced then zero amps will flow all the way up to 100 amps if only one leg of the three phase system is used. The neutral in a wye three phase system carries only the unbalanced current. This is why in services for a three phase four wire system you are allowed to reduce the size of the neutral conductor.
To calculate the amperage for a 10kW heater on a 3-phase 220V system, use the formula: Amps = (kW x 1000) / (√3 x Volts). So, Amps = (10 x 1000) / (√3 x 220) = 26.18 amps per phase. Therefore, the total current drawn by the heater is 26.18 amps per phase multiplied by 3, which equals approximately 78.54 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.
You need to specify the phase. I assume it is 3 phase system. Then the HT current is 30.3 amps

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 a three-phase 225 amp panelboard, each phase will carry 225 amps. This means that the total current flowing through the panelboard is distributed evenly across the three phases, allowing for a maximum of 225 amps on each phase at a time.
Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.
