What is the full load current of a 1 hp motor?
For single phase motors, NEC table 430-148 gives 230 Vac full load current of 8 amps for a 1 HP motor.
How do you calculate amps from motor HP?
How to Convert Horsepower to Amps
- Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
- Watts = Horsepower × 746.
- Watts = Wattsη
- Amps = Watts ÷ Volts.
- Amps = HP × 746V × η × PF.
How many amps does a 1 HP 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|
How much current would a 1.5 HP 240v motor draw?
1 Horsepower is 745.7 watts, so a 1.5 HP motor would require a maximum of 1118.55 watts. 1118.55 W / 220V equals 5.084 amps, so in theory your motor will need just over 5 amps of current.

How do you convert HP volts 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.
