The formula you are looking for is I = W/E. Amps = Watts/Volts.

depends what the source voltage isone horsepower equals to 746watts (assuming 100% efficiency)746 watts divided by voltage source equals current (amps)AnswerIn countries, such as the USA, where the horsepower is still used as a means of measuring power, it is always used to measure the output power of a motor.So, in order to determine the current drawn by the motor, you will first need to find out its input power. The input power is the output power divided by the machine's efficiency. Once you know its input power, then you can find its current by dividing the input power by the supply voltage. In practise, you will need to use a wattmeter to determine its input power.
for three phase the calculation is 30,000 = 1.73*V*I - simple as that. For single Phase the calculation is 30,000 = V*I - simple as that It is important to note the voltage in the first line is Line to Line (typically how it is specified in three phase power systems), and the second line it is Line to neutral. A 30KVA transformer is the same as 30,000VA to find out the Amps you need to divide the voltage if the transformer is single phase for example: 30,000VA / 480V = 62.5 Amps The calculation for a 3 phase transformer is the VA / voltage / 1.73 for example: 30,000VA /480V / 1.73 = 36.12 Amps
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
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
The equation that you are looking for is Amps = Watts/Volts. There are 6000 watts in 6kW.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
To calculate the amperage, you can use the formula: Amperes = Watts / Volts. So, for a 500 kW system at 240 volts, the amperage would be 2083.33 Amps.
The formula you are looking for is , A = kva x 1000/Volts.
A 18000 watt generator supplying power at 240 volts would supply 75 amps (18000 watts รท 240 volts = 75 amps).
It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.
50 Amps Single Phase 20 Amps Three Phase
At 240v single phase it's 70.8 amps. If it runs on 2 wires plus ground, take the voltage rating of the equipment and divide that into the watts to get amps. At 480v 3 phase it's 25.8 amps. At 208v 3 phase it's 47.2 amps. <<>> There are zero amps in 14 kW. A voltage needs to be stated. I = W/E, Amps = Watts/Volts.
To calculate the amperage for 3 horsepower at 208 volts, use the formula: Amps = (HP x 746) / (Volts x Efficiency). Assuming 90% efficiency, the calculation would be: (3 x 746) / (208 x 0.90) = 10.69 Amps.
Rephrase your question, as it doesn't make any sense. If the primary side of the transformer is 480 volts 3 phase, this transformer can be supplied from a breaker as big as 180 amps. If 480 volts 3 phase is your secondary then you can supply up to 180 amps to your loads.
