what is the full load amps for 2.4 hp motor at 460 volts ?
The current draw is about 27 amps. A motor feeder has to be 125% of the motors full load amperage. 27 x 125% = 33 amps. A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps.

T430.247 of the NEC shows that a 1 hp motor operating at full load on 115v will draw 16 amps, called Full Load Current (FLC). Conductors supplying this motor are required to be 125% of FLC which is 20 amps. Motor circuits are complicated things and do not follow the rules of other circuits. This motor, while drawing a maximum of 16 amps at full load and supplied with #12 AWG copper conductors can be protected by a breaker of 40 amps.
There are zero amps in 3000 volts. A load needs to be connected to the voltage.
If your generator is rated at 1000 watts continuous......and you are using 120V.....available amps are 1000/120 =8.3 .
FLA is the nameplate amperage rating of the motor when it is running at its designed horsepower and on the motors designed voltage. 746 watts = 1 HP. The FLA of a 1 HP motor at 240 volts would be W = amps x volts, Amps = Watts/Voltage. 746/240 = 3.1 amps full load. Overload the motor and the amps go higher, motor running at no load amps are lower than FLA
20.833 amps at 240volts equals 5000 watts. Wattage is volts times amps.
Full load amps is the maximum rated amps that the motor should draw according to its nameplate rating. Running load amps is the actual amperage the motor is drawing at that point in time when the test is taken. Some motor loads vary depending on if the load is cyclic. The reading on this type of motor would be from no load amps to full load amps.
Read the specification plate on the motor to determine the amount of current that the motor uses, as well as the voltage and phase. Most likely, it will be a 3 phase motor, so you can't simply connect it to your house wiring, but without sufficient information, it is impossible to tell you all of the specifics. <<>> The code book rates the amperage of a three phase 40 HP motor by different voltages. at 200 volts - 120 amps, 230 volts - 104 amps, 460 volts - 52 amps and 575 volts - 52 amps. A breaker for a motor has to be sized to 250% of the motors full load amps. Also the wire size for a motor has to be 125% of the motor full load amps.
If the nameplate states 20 amps then that is the full load amperage when the motor is running. The start up current on the motor could reach 300% of the FLA depending on the type of motor and the load that is connected to the motor.
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
FLA = full load amps <<>> It is a term that is associated with motors. It is the amperage of the motor when it operates at its full rated horsepower under load.
Full-Load Amps
Across the line starting of a motor can be as high as 300% of the full load amps.
The current draw is about 27 amps. A motor feeder has to be 125% of the motors full load amperage. 27 x 125% = 33 amps. A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps.
If the total bank is 750kVA, full load amps is 902A.
Full load amps is the amperage at which the motor was designed to work at to achieve its rated horsepower. Service factor amps is the amount of a periodic overload at which a motor can operate without overload or damage. Continuous operation within the service factor amps will shorten the insulation and motor bearing life of the motor as the motor will be operating at a higher temperature than it was designed to.
