What will be the starting current of a 335hp Sqcage motor on no load?
Across the line starting of a motor can be as high as 300% of the full load amps.
What is the FLA at 230 volts with nameplate amps of 20 and voltage of 230?
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.
What Generator size is needed for 10 hp 480 volt 3 phase motor?
Watts and horsepower are directly related as they are both measurements of power. 1hp = 745.6998 watts. So 3kW = 3000W / 745.6998 W/hp = 4.023hp You need a minimum of 4hp, which will give you a max of 2982W before any losses in your generator. You should probably go with a 4.5 or 5 horse motor.
A particular 3 phase induction motor has a LRA of 100 amps What is its approximate starting current?
LRA (locked rotor amperage) is not considered. Starting current for a motor is usually in the neighbourhood of 300% of the FLA (full load amps). The FLA is taken from the motor's nameplate.
What size of circuit breaker do you use for 25amperes induction motor?
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.

Reasons why a 5500 watt generator will not run a well pump?
It could be a number of things. Your pump's operating voltage could be 240 volts and your generator's output is only 120 volts. The generators output voltage can be found on the generator's nameplate. The horse power size of your pump could be too big for your generator. When dealing with motors remember that when a motor starts its inrush could be 300% of the full load amps. To see if this is happening, take the full load amps and multiply it by 3. Then multiply that number by the voltage that the pump runs on. This number will be the starting watts of the pump. If this number is higher than that of your generator and the generator almost comes to a stop when the load is applied,then the generator is too small.
What is the FLA at 230 volts with nameplate amps of 20 and voltage of 230?
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.
1000 watt generator power can it power a oil burner?
Watts = amps x volts. 1000/120 = 8.3. Assuming the oil burner motor is 120V then the generator has the ability to produce 8.3 amps. Find the amperage on the burner pump motor, if it is in this range it will work. The closer the pump amperage is to the generator output the more effect it will have on slowing the generator down on the start. Motors draw up to 300% on start up, this is what makes the generator lag when a motor is connected as a load.

Would a one third horsepower single phase motor that normally operates at 6.8 amps draw 34 amps at start up?
Not usually. The rule of thumb is 300% of the full load amps. The only way that you can check this inrush current is to have a clamp on amp-meter with the setting on Hold. What this does, is sense the highest current at start up and holds the reading on the screen until you release it. If you try and start a motor under a high inertia load the current will rise above a normal inrush level. Disconnect the load from the motor to establish that it is the load that is causing the high amperage and not the motor's internal wiring.
What size wire do you need to run a 220 pump 40 amp breaker 130 feet?
This is a tricky question to answer without all of the information necessary for calculations. A motor has to have a breaker sized at 250% of the motor's full load amps. Wire is sized by the amount of amperage that it is allowed to carry.If the breaker is sized at 250% then the motor's full load amperage must be 16 amps if this is the case then the conductor for 16 amps at 130 feet will be #12 copper or #10 aluminium. the insulation rating for the conductors must be 90 degrees C.If the motor's full load amperage is 40 amps then the conductors, both copper and aluminium must have an insulation factor of 90 degrees C ad the wire size will be #6. The breaker for this pump must then be a 100 amp breaker. The larger size breaker is used so that it does not trip due to the inrush current when the motor starts. It could be in the range of 300 to 600% of the motors full load amperage.
What size awg do you need to install a 240v rec on a 50a breaker?
#8. It is better to error on the next large size. # 8 THHN 90 degree wire is rated at 45 amps. If there is a possibility that the breaker is connected to a 50 amp load the wire will be undersized. A #6 wire is rated at 65 amps. For continuous use, a load factor of 80% has to be applied. 65 x .8 = 52 amps. The only time the conductor can be smaller than the breaker size is on a motor feeder. Then the breaker is sized at 250% of the nameplate full load amps (FLA) rating of the motor. This is to allow the motor's starting current, which is about 300% FLA, to not trip the breaker on start up.
How many amps does a 2HP motor draw on start up?
The rule of thumb for fusing the motor is 300% of the full load amps. To answer this question a voltage value for the motor is needed. That would depend on the type of electricity used and the type of motor. The answer will be different for DC, single phase AC, two phase AC, and three phase. There are many types of motors as well: split-phase, brush less, squirrel cage, synchronous, etc. Each one has different characteristics.
What speaker wire for 300 watt amp?
There is no such thing as a watt amp. To determine wire size you need to know the current. Watts = Current x Voltage, so if you know the applied voltage to the load that consumes 300 watts you can get the answer. If we assume 120 volts as standard home voltage then current is 25 amps. If you had 240 volts it would be 12.5 amps. In general 14 AWG is 15 Amps 12 AWG is 20 Amps 10 AWG is 30 Amps
