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 2 hp pump draw?
To answer this question the pump's voltage is needed.
How many amps does a 0.75 hp 550 volt single phase motor draw?
At peak power it should draw 1.36 amp at power factor 1 or more realistically 1.7 amp at power factor 1.7.
What size wire do you need for a 240 volt 3 hp well pump that is 700ft from power source?
To answer this question accurately the amperage of the motor must be given. Using 746 watt equals one horsepower will not be as accurate but will be close to the correct wire size. The equation for amps when HP is known is I = HP x 746/E x %eff x pf. Amps = 746 x 3 = 2238/240 x .84 x .86 = 2238/173 = 13 amps. A standard motor's efficiency between 5 to 100 HP is .84 to .91. A standard motor's power factor between 10 to 100 HP is .86 to .92. A #4 copper conductor will limit the voltage drop to 3% or less when supplying 13 amps for 700 feet on a 240 volt system. The electrical code book states that a 3 HP motor on 230 volts draws 17 amps. If this is closer to what you pump draws then the wire size will be; A #4 copper conductor will limit the voltage drop to 3% or less when supplying 17 amps for 700 feet on a 240 volt system.
How many watts does a water pump use?
It would depend on how deep your well is, and how efficient the pump.
How many amps does a 240 volt and 8 hp motor draw?
24.87amps 1 hp=746 watts P=IxV ... (746x8)/240
How many amps 50 hp 240 3 phase?
106 amps
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 2 hp pump draw?
To answer this question the pump's voltage is needed.
Will a 10 hp 220 volt motor draw large amounts of electricity?
A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.
How many amps does a 15 hp motor draw?
To answer this question the voltage of the motor must be stated.
How many amps does a five horse power motor draw?
It depends on the voltage-- I think at 110v it's 4 amps per hp
What formula is used to find amps when hp and volts are known?
For a single-phase induction motor, allow 7 amps on a 240 v for a 1-HP motor. Therefore the formula is: current = 7 X HP x 240 / voltage
How many amps is a 3 hp 240 volt motor use?
AWG #10 copper on a 30 amp breaker.
How many amps will a 75 hp dc motor draw?
HP = (Current x Voltage)/746, or HP = (IE)/746 (disregarding %Efficiency) So, you have to solve for I, current: I = (746 x HP)/E
You have 3.7 kw 5 hp motor is their how much ian amps?
current = power/ voltage current = 3700/ 240 = 15.4 amps
How many amps does 1 phase 220volt 7.5 HP draw?
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.
