Look at the motor nameplate and it shoud have the amp draw on it. If the nameplate is missing, then the amp draw depends on what type of motor it is.
The basic calculation to get you in the ball park would be as follows:
1 HP = 0.75 KW
7.5 HP = 5.63 KW
Assume the efficiency of the motor is 80%, then the power supplied will need to be 5.63/0.8 = 7.04 KW
amp draw = 7040/220 = 32 amps
<<>>
For calculation purposes the electrical code book states that a 7.5 HP motor draws 40 amps.

How many amps does a 10kw heater draw that's 3phase 220volt?
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.

How many amps does 30KW strip heater draw at 208 volts 3PH?
To calculate the current draw, use the formula: Current (A) = Power (W) / (Voltage (V) * √3). Plugging in the values, we get Current = 30000W / (208V * √3) ≈ 78.7A. So, a 30KW strip heater operating at 208 volts 3-phase would draw approximately 78.7 amps.
How many amps does a 1.5 hp 230v 3 phase motor draw?
For a 1.5 hp 230v 3 phase motor, you can calculate the amperage using the formula: Amps = (HP x 746) / (Volts x Efficiency x Power Factor x √3). Assuming an efficiency of 0.85 and a power factor of 0.8, the amperage draw would be approximately 4.3 Amps.
How many amps does a 208 volt 3 phase 45 kw hot water heater draw?
To calculate the amperage, you can use the formula: Amps = (kW × 1000) / (√3 × Volts). Plugging in the values, we get: Amps = (45 × 1000) / (√3 × 208) ≈ 131.1 amps. So, the hot water heater would draw approximately 131.1 amps.
How many amps will a 480 volt 3 phase 35 kw heating element draw?
To calculate the current draw of a 480-volt, 3-phase, 35 kW heating element, you can use the formula: [ I = \frac{P}{\sqrt{3} \times V} ] where ( I ) is the current in amps, ( P ) is the power in watts, and ( V ) is the voltage. Substituting the values: [ I = \frac{35000}{\sqrt{3} \times 480} \approx 42.1 , \text{amps} ] Therefore, the heating element will draw approximately 42.1 amps.
