Common Horsepower to Amps Conversions

Horsepower | Amps | Voltage |
---|---|---|

1.5 HP | 10.4 A | 120 V |

1.75 HP | 12.1 A | 120 V |

2 HP | 13.8 A | 120 V |

2.5 HP | 17.3 A | 120 V |

## What size breaker do I need for a 2 hp motor?

How to Calculate How What Size Circuit Breaker a Machine will Need:

HorsePower of Main Motor | 220 Volts, 1 phase | 220 Volts, 3 phase |
---|---|---|

1 Hp | 5.6 Amps | 2.8 |

2 | 11.2 | 5.6 |

3 | 16.8 | 8.4 |

4 | 22.4 | 11.2 |

## How many amps does a 2 HP 240 volt motor draw?

AC Motor Full Load Amperes

HP | 200 Volts | 220-240 Volts |
---|---|---|

1 | 4.8 | 4.2 |

1.5 | 6.9 | 6 |

2 | 7.8 | 6.8 |

3 | 11 | 9.6 |

## How do you calculate amps from motor HP?

The conversion from amps, a measure of electric current, to horsepower, a measure of power output by a motor, can be done using a fairly simple formula. Thus, horsepower is equal to the current in amps times the voltage in volts times the efficiency times the power factor, divided by 746.

## How many amps does a 2.2 kW motor draw?

Three Phase Motors

MOTOR RATING | HP | |
---|---|---|

0.75 kW | 1 | 3.2 |

1.1 kW | 1.5 | 4.5 |

1.5 kW | 2 | 5.8 |

2.2 kW | 3 | 8.7 |

## How many amps does a 1.5 HP 220v motor draw?

The 1.5 HP Baldor motor that turns at 1725 will draw 18 amps according to its name plate.

## What size breaker do I need for a 1.5 hp motor?

Assuming that it is single phase, a 15 ampere circuit breaker should be adequate and will allow extra current for starting and surges.

## How many amps can you put on a 20-amp breaker?

The standard for most household circuits are rated either 15 amps or 20 amps. An important note to remember is that circuit breakers can only handle about 80% of their overall amperage. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.

## What size breaker do I need for a 2 HP well pump?

Pumps Under Full Load

Well Pump (HP) | Volts (V) | Circuit Breaker (Amps) |
---|---|---|

1 HP | 230V | 25A |

1.5 HP | 230V | 30A |

2 HP | 230V | 30A |

3 HP | 230V | 40A |

## What is the input current of 2hp single phase motor?

Full-Load Current in Amperes Single-Phase Alternating Current Motors

HP | 115V | 230V |
---|---|---|

^{3}/4 |
13.8 | 6.9 |

1 | 16 | 8 |

1 – ^{1}/2 |
20 | 10 |

2 | 24 | 12 |

## How many amps does a 1/2 HP well pump draw?

When delivering 1/2hp to the pump, it draws 5.0 Amps. If that motor operates at its service factor of 0.8, it will draw 6.0 Amps. Most installations have motors near the maximum load.

## How much current does a motor draw?

Calculate the amps used by dividing the wattage by the voltage. For example a 500-watt motor — running on 50 volts — will draw 10 amps. A motor with the same wattage — running on 20 volts — will use 25 amps. This is the theoretical number of amps used by the motor.

## How many amps does a 1.5 hp submersible pump draw?

1.5 hp is 1152 watts. If you use 120 volts, the current is: 9.6 amps.

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

Here are the Full Load Amp (FLA) values for typical 230VAC and 480VAC 3 phase motors.

Motor horsepower | Full load amps 230VAC | Full load amps 460VAC |
---|---|---|

1.5 | 4.7 | 2.4 |

2 | 6 | 3.0 |

3 | 9 | 4.5 |

5 | 15 | 7.5 |
