How do I convert HP to amps?
Converting horsepower to amps can be done in a few simple steps, or using this simple formula.
- Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
- Watts = Horsepower × 746.
- Watts = Wattsη
- Amps = Watts ÷ Volts.
- Amps = HP × 746V × η × PF.

What size breaker does a motor need?
You must size the conductors at 125% of the motor FLC [430.22(A)]. You must size the overloads no more than 115% to 125% of the motor nameplate current rating, depending on the conditions [430.32(A)(1)].
What size breaker do I need for a 7.5 hp motor?
You need 50 amp rated wire with a 50-100 amp breaker.
How many amps is a 3 phase 5hp motor?

How do I know how many amps my 3 phase motor is?
Find the power factor (p.f.) on the identification nameplate. For a purely resistive circuit, the power factor equals 1.0 (perfect). Substitute the value of the power you need to convert (in watts), the value of the voltage (in volts), and the power factor to find the current (in amps). The current is 187 amps.
How many amps does a 5 hp motor use?
A 5 HP motor at 230V, 3PH is12.
Using the formula above, multiply 12.4 amps by 10% for a result of 1.24. Add this total to 12.4 for a total of 13.64 amps.
What is the full load current of a 1 hp motor?
For a 1 HP 3phase induction motor draws a current =W /V, so 1 HP is equal to 746 watts, or rounded off to 750 watts, so it will be 750 /415 volts =1.7 amperes, approximately and at a powerfactor at unity means 1.
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 many watts is a 1 hp motor?
One electric horsepower is equal to exactly 746 watts.
