## How do I convert HP to amps?

Convert to Amps

1. Amps = 1 HP × 746 W120 V × .9.
2. Amps = 746120 V × .9.
3. Amps = 746108.

## How many amps does a 12v 1hp motor draw?

0.2 HP = 17 amperes. 0.5 HP = 42 amperes. 1.0 HP = 85 amperes.

## How do you calculate amps on a motor?

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.

## How many amps does a 1 HP pool pump draw?

1 HP is 746 watts x 1.5 HP = 1,119 watts. 1,119watts ÷ 120volts= 9.325 amps.

## How much current would a 1.5 HP 240v motor draw?

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

## How much current can a 5 hp motor take?

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

HP 115V 230V
5 56 28
7-1/2 80 40
10 100 50
The voltages listed are rated motor voltages. The listed currents are for system voltage ranges of 110 to 120 and 220 to 240.

## What size breaker do I need for a 3 HP motor?

What size breaker do I need for a 3 HP motor? A 20 amp breaker is all you’d ever need for a 220v 3HP motor. It wouldn’t hurt anything to run 30amp circuits if you so choose, but it’s overkill.

## How many amps will a motor draw?

Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts. Watts = Horsepower × 746. Watts = Watts ÷ Efficiency. Amps = Watts ÷ Volts.
