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.

read the name plate on the motor
How many amperes for 3 phase 220v 5 tonner?
50 Amps Single Phase 20 Amps Three Phase
How many amps does a 2 hp 210 volt single phase motor draw?
Then you are trying to get more HP out of the motor that it can supply. Back off on the load that the motor is driving or put a bigger motor onto the load.
7200 volt 25kw transformer how many amps at 240 single phase?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
How many amps does an hho generator draw?
depends on the number of cans and the specific gravity of the electrolyte
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 will a 3 phase 480 volt 4kw heater draw?
To calculate the amperage drawn by the heater, you can use the formula: Amperage (A) = Power (W) / (Voltage (V) * Square root of 3). In this case, the amperage drawn will be approximately 5.8 Amps.
How many amps at 415volt is 80amps at 220volt?
X / 415 = 80 / 220 = 151 amps
How many amps does a 2000 watt heater draw at 240 volts on each line?
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
How many watts is 1 hp at 480volts?
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.
How many amps does a 1 phase heater draw if it run on 8kw?
To answer this question the voltage of the heater must be given. I = W/E.
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 on 3 phase 225 amp panelboard each phase?
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.

How many amps will a 20 KW heat strip draw on 480 volt three phase?
24 amps. This could be three 11.54 resistors connected in star, or three 34.6 ohm resistors connected in delta.
