If you had to ask this question here you need to learn more about your local wiring code re all the items you must use for this new motor circuit.
So that the new installation is safe and legal - and complies with the terms of your home or business insurance policy - you must use the correct type and size of cable, the correct type of circuit breaker and the correct type of wall outlet.
Serious home fires can result from incorrectly-installed new circuits.
Another answer
NEC table 430.248 lists this motor as drawing 17 amps, !7 x 1.25 =21.5 amps. Number 10 copper wire.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What are the procedures for the connection of single and 3 phase circuits?
Single phase connection has 1 phase wire and a neutral wire. Another wire for protective earth. In three phase system, motor can be connected in star or delta. Most AC induction motors are in Delta. Power distribution system is generally 3 phase 4 wire. Transmission system is 3 phase high voltage. Industry uses 3 phase system, where as 1 phase is for domestic, commercial applications. Both 1 and 3 phase system has a frequency. It is either 50 Hz or 60 Hz, depending upon the country or region.
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.
What is RPM of a 2 pole single phase motor?
3600 rpm 120x60/2=3600 where 120 is given 60 cycle 2 pole
How star delta helping motor from overheat?
star delta motors start as a Y for 3 phase so the windings that normally see 480 volts see 277V a relay switches to delta then it runs as a normal delta motor the reduces the starting current by about 60% for 3 phase
Can you run a 460 volt 3 phase 60 hertz refrigeration compressor on 460 volt 3 phase 50 hertz?
Possibly. You need to check the rating on the device. Many compressors can operate on either 50 or 60 Hz.
Minimum breaker size 60 horsepower motor?
Need motor voltage, amperage and phase to give you an anwer.

The synchronous speed of a four pole 60 hz single phase motor is?
3600 rpm
What size of wire and breaker do you need for a 10 KW electric furnace?
To answer this question, wire size is rated in the amount of amperage that it can legally carry. The formula to find amperage when the HP is known is I = HP x 746/1.73 x E x %eff x pf. A standard motor's efficiency between 5 to 100 HP is .84 to .91. A standard motor's power factor between 10 to 100 HP is .86 to .92. Amps = 10 x 746 = 7460 = 7460/1.73 x 220 x .84 x .86 = 7460/275 = 27.1 amps. The electrical code states that a motor conductor has to be rated at 125% of the motors full load amperage. 27.1 x 125% = 33.8 A #8 copper conductor with an insulation factor of 60, 75 or 90 degrees C is rated at 40, 50 and 55 amps respectively.
What Size breaker for 6 gauge wire?
You need a 60 amp breaker.
What size wire for a 45 AMP fuse?
what size wire would be required for an ak012 with a power supply of 208/240-3-60 hz
Can you use ten gauge wire on a compressor rated at thirty three amps?
Assuming that the motor is single phase 3 HP operating on 120 volts. A couple of things come into play on this installation. One it is a motor load. Code states that motor loads have to have feeders rated at 125% of the motors full load amps (FLA). The other condition is breaker sizing. With a motor amperage of 33 amps and using a feeder of 125% means 33 x 125% or 1.25 = 41.25 amps for wire sizing. A #10 copper wire with an insulation rating of 60, 75, or 90 degrees C is rated at 30 amps, this does not fall within the required wire size. A #8 copper wire with an insulation factor of 75 or 90 degrees C is rated at 45 amps, this falls within the required wire size. Breaker sizing is taken from the motors FLA. For a motor with 34 amps full load, a 110 amp non time delay fuse, 60 amp time delay "D" fuse or a 70 amp breaker is required to meet code regulations. The reason for over sizing the breaker or fuses is to overcome the motor high current, which can rise to 300% of the motor's FLA, on start up.

Can a 415V 3-phase 50 Hz motor run on 380V 3 phase 60 Hz?
Yes, it will run drawing little more extra current in similar conditions. The motor is expected to be running in lesser rpm as well.
Why ground the neutral of a 3 phase ac motor?
In a three phase motor each leg (3 phases) in the down cycle alternating at 1/60 per second servers as a neutral, you are only required to ground (green) the frame of the motor for safety. This is similar In a single phase motor wired for 240v (2 phases) the same thing happens and you are only required to ground (green) the frame of the motor for safety. From: Ken F
