How many amps does a 10 hp motor use?
AMP DRAW BASED ON HORSEPOWER
| HP | 1 Phase Amps | 3 Phase Amps |
|---|---|---|
| 115 volt | 208 volt | |
| 5 | 56 | 16.7 |
| 7-1/2 | 80 | 24.2 |

How do you calculate amps from volts and horsepower?
Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm’s Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.
Is amps the same as horsepower?
Amperes are a measure of the rate of flow of electricity, whereas horsepower is a measurement of work divided by time, so amperes and horsepower cannot be equated or converted to one another (it would be like trying to convert pounds to miles). Look for numbers with a unit of A or Amp for amperes and V for volts.
What size breaker do I need for a 10 hp motor?

How many amps does a 7.5 hp motor take?
7.5 Hp 3-phase motor takes 9.7 Amps, 10 HP, 3 phase motor takes 13 Amps Look at that, while increasing the horsepower rating the ampere value and motor size also will be increased. Learn More: VAR to kVAR Conversion Calculator
How to calculate horsepower and amps for a motor?
Amps = HP × 746 V × η × PF. Thus, the current in amps is equal to horsepower times 746 divided by the voltage times the efficiency η times the power factor. For example, let’s find the current draw in amps of a 1 horsepower motor that runs at 120 volts with a 90% efficiency. Amps = 1 HP × 746 W 120 V × .9. Amps = 746 120 V × .9.
What is the ratio of HP to amps?
In DC circuits amps is the ratio between the product of HP * 746 to Voltage times efficiency. Example: Find the current passing through 24 volt, 1/2 HP motor having an efficiency of 95%.
