3 amps on 120 volts is almost 1/2 hp. To be exact 0.48 hp, that's why I said almost 0.5 hp or 1/2 hp.
So say you are thinking of buying a 3 amp grinder or table top sander and you want to know about how many HP (Horse Power) it is, the answer is 120 volts X 3 amps = 360 X 0.00134 = 0.4824 HP which is almost a 1/2 HP
you can do the math from there if its a 6 amp motor then its almost a 1 HP motor or to be exact 0.4824 X 2 = 0.9648 also almost 1 HP. This is if you are on 120 volts. If you are on 110 or 125 volts its about the same.
The exact amperage required for a 3 horsepower motor will depend on the voltage at which it operates. Typically, for a single-phase motor operating at 120 volts, a 3 horsepower motor would draw around 25 amps. For a three-phase motor operating at 230 volts, it would draw around 10 amps.
3 horse power if it is 3phase system then it will draw apx.4.5 amps if supply voltage is 440 volts ,at frequency 50 cps. the current needed depends up on supply system parameters.

How many Amps for 3 horsepower at 208 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.
How many amps is 3000 milliamps?
3000 milliamps is equal to 3 amps. To convert milliamps to amps, you divide by 1000.
How many amps 3 pH 2 hp 240 v draw?
100 amps
How many amps in 3 AA batterys?
3 AA batteries provide about 4.5 volts. The amps depend on the load but for D-cells a load of 10 amps can be sustained for short periods.
How many amps is 2 hp at 230V 3 phase?
6,25AnswerWithout knowing the efficiency of the motor, it's impossible to tell. The horsepower rating of a motor describes its output power; you need to know its input power in order to calculate its current.
How many things are needed to have current?
3 things Volts, ohms, and amps

Looking for a basic standard type answer to how many circuit breaker amps are needed per motor horsepower on 3 phase?
The main breaker is not based on the HP of the motor it is based on the FLA of the motor. Many different motors have different characteristics and all of the different motors have different amperages Once you have the amperage of the motor the breaker is 250% times the FLA of the motor.
How many amps 3 pH 2 hp 240 v draw?
100 amps

How many amps in 3 AA batterys?
3 AA batteries provide about 4.5 volts. The amps depend on the load but for D-cells a load of 10 amps can be sustained for short periods.
Who many amps are needed to feed a 600 v to 480 v 3 phase 70 KVA transformer?
The equation for amperage when the kilowatts are known is Amps = kVA x 1000/1.73 x Volts.The electrical code states that a feeder for a transformer has to be rated at 125% for the primary and secondary load amperages.The amperage on the primary needed to supply a 70 KVA three phase transformer to its full capacity at 600 will be 68 amps. 68 x 125% = 85 amps. A #4 copper conductor with an insulation factor of 90 degrees C is rated at 95 amps.The amperage on the secondary needed to supply a 70 KVA three phase transformer to its full capacity at 480 will be 84 amps. 84 x 125% = 105 amps. A # 3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps.
