The question is impossib;e to answer without knowing the supply voltage.

<<>>

What ever the motors full load amperage is, the breaker has to be sized to 250% of that FLA.

Minimum breaker size 60 horsepower motor?

A 60 horsepower motor typically requires a minimum breaker size of 100 Amps for normal operation. It is important to consult the motor's specifications or a licensed electrician to ensure the correct breaker size for safe and efficient operation.


How do you use a one phase motor in place of a three phase motor?

To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.


Up to how much HP are single phase motors maufactured?

Horse power is horse power, regardless of what voltages and currents are used. 5 HP single phase is equal to 5 HP 3 phase.


Will it hurt 230 volt single phase motor plugged into 277 V single phase?

Yes, plugging a 230V single phase motor into a 277V single phase power supply can potentially damage the motor due to the higher voltage. It is recommended to match the voltage ratings of the motor and power supply to prevent any issues.


What is the simplest way to run a 3 phase 380 V motor of about 1 KW directly on 220 V single phase supply without resorting to rewinding or frequency converters?

You cannot run a three phase motor on single phase power. You'll burn the motor up within minutes. By the way, I've never seen or heard of a 380 volt motor. Do you mean a 480 volt motor? If so, the only way you can power it is with the correct full voltage and a 3 phase power supply.

What would be the horse power required in a 3-phase motor to replace a .5 horsepower single phase motor.?

You still need the same horsepower. The advantage of the three-phase motor is that it will draw lower current.


What single phase motor should you use to get out the same power as a 3 phase one and a half HP motor It's going on a lathe and I don't want to find that a singel phase one and a half motor labors?

One And a Half Horse Power Obviously.


Can you replace a three phase motor 3 Hp RPM 1420 with a single phase motor for a planer?

Probably not. The single phase three horse power motor will be much larger in physical size than its three phase counterpart, and will probably not fit.


How many current needed for the starting of a 5 horse power single phase motor?

120 volt


Which type of the motor is used in fan?

Low-power (a few watts) might use a synchronous motor, most fans use an induction motor. Above a couple of horse-power it might be a 3-phase induction motor.


One horse power single phase motor is more likely to get hot than a one horse power 3 phase motor. Is it true or false if true why?

True. A single-phase motor typically has a lower starting torque and may operate less efficiently than a three-phase motor, leading to higher heat generation during operation. Additionally, single-phase motors often have poorer thermal dissipation due to their design, making them more susceptible to overheating under load compared to the more efficient and balanced operation of a three-phase motor.

How is a three phase agricultural motor used when there is no power supply?

With no three phase power supply you can't use a three phase motor of any kind at all!


Can you wire a 3 phase 690 volt delta star motor to 480 volt 3 phase with out harming the motor?

Depends on the motor and the load on that motor. If the motor is loaded to its capacity, it will draw the same amount of power as it would on 690 volts - which will result in ( 690/480 = ) 144% of normal current, which will thermally damage the motor, or will trip overload protection.
