What is the start up amps on a 200 hp 3 phase 480 volt motor?
i have 200 hp motor what i need cable size in 100 feet distance
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.
What is the amp load of 125 hp 480 volts 3 phase motor?
The electrical code states that a 50 HP 460 volt three phase motor draws 65 amps. The ideal amperage would be taken from the motors nameplate as different motors of the same horsepower will have different amperage's depending on what they are designed to do.
What size power cord for a 30 hp motor 480 volts?
To answer this question, wire size is rated in the amount of amperage that it can legally carry. The formula to find amperage when the HP is known is I = HP x 746/1.73 x E x %eff x pf. 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. Amps = 30 x 746 = 22380 = 22380/ 1.73 x 480 x .87 x .87 = 22380/629 = 35.6 amps. The electrical code states that a motor conductor has to be rated at 125% of the motors full load amperage. 35.6 x 125% = 44.5 A #8 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 50 and 55 amps respectively.
How much does a 10 hp pump draw 480 volt?
A 10 hp pump operating at 480 volts would draw approximately 15.6 amps of current. This can be calculated by dividing the power in watts by the voltage.

What is max single phase hp as per nec?
The maximum single phase HP motor listed in the CEC is 10 HP. At 115 volts 100 amps and 230 volts 50 amps.
What is the full load amps for 2.4 hp motor at 460 volts?
what is the full load amps for 2.4 hp motor at 460 volts ?
How many watts is 1 hp at 480volts?

How much does a 10 hp pump draw 480 volt?
A 10 hp pump operating at 480 volts would draw approximately 15.6 amps of current. This can be calculated by dividing the power in watts by the voltage.
Hp equals 60 and volts equals 480 what are the amps?
746 Watts per horsepower / 480 volts x power factor x efficiency x 1.73 = amps assuming that the motor is three phase. 746 x 60 =44760 watts divided by 480 x 1.73 = 53.9 amps ( If the pf and eff. information is not known this will put you in the ball park)
How many watts will it take to run a 120 volt 1 hp motor?
A 1 HP motor running at 120 volts will draw approximately 746 watts. This calculation is based on the formula: Watts = Volts x Amps.
How many ampere in one hp?
There are 746 watts in 1 HP. Watts = amps x volts. It depends on the voltage rating of the motor. Amps = 746/volts = ? need voltage.
How many amps will a 3 hp motor pull on 230 volts?
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.
What size wire for a 480 volt 60 hp motor 220 feet away?
Wire is sized by the load amperage. The formula for amperage when the HP is known is I = HP x 746/1.73 x E X %eff x pf. 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. I = 60 x 746 = 44760/ 1.73 x 480 x .89 x .89 = 44760/658 = 68 amps. Motor feeders have to be sized to 125% of the motors full load amps. 68 x 125% = 85 amps A #3 copper conductor will limit the voltage drop to3% or less when supplying 85 amps for 220 feet on a 480 volt system.
