How do I know what AMP my HP is?

Converting horsepower to amps can be done in a few simple steps, or using this simple formula.

  1. Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
  2. Watts = Horsepower × 746.
  3. Watts = Wattsη
  4. Amps = Watts ÷ Volts.
  5. 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 is full load amps on a motor?

Full Load Amps, or F.L.A., represents the amount of current the motor is designed to draw at the rated horsepower. In the example nameplate, this means that when the motor is running under a full load at 230 volts, we can expect it to draw 5.4 amps.
