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.
How do you calculate amp draw on a motor?

The 1.5 HP Baldor motor that turns at 1725 will draw 18 amps according to its name plate.
What causes a motor to draw too many amps?
Electrical overload or over-current is caused by an excessive current flow within the motor windings, exceeding the design current which the motor is able to carry efficiently and safely. This can be caused by a low supply voltage, resulting in the motor drawing in more current in an attempt to maintain its torque.
How many amps does a 1.5 hp air conditioner use?
Answer: 20 Amp circuit breaker is enough for a 1 HP motor air conditioner.Circuit Breaker for Air Conditioner Table. Circuit breaker for 0.5 HP Air Conditioner 15 Amp or higher Circuit breaker for 1.5 HP Air Conditioner 30 Amp or higher.
What is the formula to calculate amps?
Calculating Amperage A simple formula for calculating amps is to take the watts and divide that by the volts. So, for instance, if the wattage of the lighting fixture you’re working with is 60 and the volts are 12, divide 60 by 12 and you will get five, which are the amps.
