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.
What is FLA and RLA?
RLA – “Running Load Amps” – current drawn during normal operation of electric motor. FLA – “Full Load Amps” – amount of current drawn when full-load torque and horsepower is reached for the motor. FLA is usually determined in laboratory tests.
How do you calculate full load amps?
The motor FLA calculator uses the following formulas:
- Single Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × cos ϕ)
- Single Phase AC Motor FLA (Amperes) = (P [HP] × 746) / (V × cos ϕ × η)
- Three Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × 1.732 × cos ϕ)

What’s the difference between full load amps and running load amps?
Full load amps is what the motor will draw at its rated voltage, speed, frequency and horsepower. change any of these and your amperage will now be running amps.
Does an electric motor draw more current under load?
In fact, typically a motor will draw much more current when stalled than when running. As more mechanical load is applied, the motor slows, the back emf decreases, and more current is drawn.
What is maximum load current?
The maximum load current is the smallest amount of current in amps that must be drawn from a particular output for that output to function.
What does Fla stand for in HVAC?
FLA – Full Load Amps.
How many kilowatts is 200 amps?
If you have a 200 Amp service panel, use a 15-20 kW GenSet (again use the larger size if you have air conditioning or large well pump). If you have a 400 amp service panel, use a 30-50 kW GenSet (if you have lots of air conditioning or other larger loads use the large size in the range).
How do I convert amps to watts?
Converting amps to watts can be done using the power formula, which states that I = P ÷ E, where P is power measured in watts, I is current measured in amps, and E is voltage measured in volts. Thus, the power P in watts is equal to the current I in amps multiplied by the voltage V in volts.
