## How much power does a 2 hp motor use?

So, 1 HP for 24 hour = 746×24= 17904 Watt-hour which is equal to 17904/1000= 17.904 units. How many kWh does a 10 hp motor use?

…

How many watts does a 1 hp electric motor use?

Horsepower | Watts | Rounded Watts |
---|---|---|

1 hp | 745.699872 W | 746 Watts |

2 hp | 1491.399744 W |
1491 Watts |

3 hp | 2237.099616 W | 2237 Watts |

## How much power does a 1hp motor consume?

So, 1 HP for 24 hour = 746×24= 17904 Watt-hour which is equal to 17904/1000= **17.904 units**. Hence, 17.904 units of Power will be consumed by the 1 HP motor when run continuously for 24 hours.

## How much electricity does a 30 hp motor use?

Designed power capacity of a motor 30 HP,at 415 V, 3 phase power factor 0.8 (assumed). Full load current is , one HP is 745 w, 30 HP is 30 x 745 =23.35 kW, W = V x I x pf, 23.35 = 415 x I x 0.8, I = 23.35 divided by 415 x 0.8 = **67 amps**.

## How many watts does a 2.5 hp motor use?

One horsepower is equal to 745.7 watts. When you multiply 745.7 watts by 2.5 hp, you get **1,864.25 watts**. Energy costs are calculated in kilowatt-hours, and to get kilowatt-hours, you multiply watts by hours and divide by 1,000.

## How do I convert HP to amps?

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.

## What size breaker do I need for a 7.5 hp motor?

Per table 310.16 – #6 wire is required. A minimum (nominal) breaker is also 50 amps but can be increased to a maximum size of 100 amps. For the purposes of the compressor a **60 amp** breaker should be used.

## How many amps does a 5 HP 3 phase motor draw?

These are only intended to be guidelines and in all cases the full load amps of the motor nameplate should be used for final calculations.
