The only thing you need to know in order to size your wire is the "5.1 amp" amount.
Figure on the motor drawing double on startup, so say, 10 amps, or so.
18 gauge wire would pack your 5.1 amps just fine, but it is a little flimsy . . . I would use 16 gauge, instead.
Of course, the insulation on the wire you select should be rated for 600 volts or more.

When does a motor not need a neutral wire?
If the motor is operated from a three phase three wire distribution system the motor will not need a neutral wire.
How do you convert a 4 wire water well pump to a 2 wire?
It sounds like you have a three phase motor that you are trying to put in where you have a single phase 120volt motor. You can purchase a three phase inverter, but the cost will exceed the cost of the new motor sized for the right wiring and voltage.
What gauge wire should be used to run a 230v motor 90 ft away?
To answer this question the amperage or the wattage of the motor must be given.
What gauge wire would you use to wire a 120V 20A motor?
I am assuming that this is a one and a half HP motor. To wire a 120V 20A motor the electrical code states that the conductor has to be 125% of the motor's full load amps. This equals 25 amps. There is no wire rated at 25 amps so the next size up is 30 amps. A #10 copper wire with an insulation factor of 60, 75 and 90 degrees C is rated at 30 amps. To carry this to a conclusion This #10 wire should be protected by either 60 amp non time delay fuses or 35 amp time delay fuses or a two pole 50 amp breaker.
Is a three phase three wire system safe?
Three-wire transmission is used on balanced three-phase systems when the current is known to be equal in all three phases, for example when supplying a three-phase motor. A fourth neutral wire is used when the system is liable to have unequal currents or when multiple single-phase supplies are connected to it.
Can a bad circuit breaker on a 3 phase motor cause the motor to run backwards?
No. If the motor runs backwards, swap any two phases to reverse the rotation, like this: Old wiring: phase A - brown wire - motor lead T1 phase B - yellow wire - motor lead T2 phase C - orange wire - motor lead T3 New wiring: phase A - brown wire - motor lead T2 phase B - yellow wire - motor lead T1 phase C - orange wire - motor lead T3
How do you reverse a direction of a slip ring motor?
It is very simple. Just interchange any two phase wires. i.e. Y and B ( or ) R and B ( or ) R and Y for example Stop the supply. keep R phase wire as it is and disconnect B phase wire and Y phase wire. Connect B phase wire to the Y phase motor stud and Y phase wire to the B phase motor stud. Now give the supply, now motor revolves in opposite direction to the earlier.
When does a motor not need a neutral wire?
If the motor is operated from a three phase three wire distribution system the motor will not need a neutral wire.
On a 220 volt electric motor which is the neutral wire L1 L2 or L3?
If the motor wire numbers are L1, L2 and L3, it is not a single phase motor. It is a three phase motor. Also for future reference, a 220 volt single phase motor does not use a neutral.
How may wire on a 3 phase motor?

How do you make a 9 wire three phase motor into a three speed motor?
You don't.
How can you determine if a electric motor is 1 phase or 3 phase if there is no name plate?
Check the motor's terminal box. If there are three service input cables - such as red, yellow and blue - plus an earth wire, then it is a three phase motor. If there are only two wires plus an earth wire, then it is single phase.
What size wire do you use on a fridge freezer?
12 gauge wire is used for household plugins, and 14 gauge wire is used for lights. So, 12 gauge is the size to use. But since a freezer has an electric motor, it is best to not plug anything else with a motor into the same circuit.
How do you convert a 4 wire water well pump to a 2 wire?
It sounds like you have a three phase motor that you are trying to put in where you have a single phase 120volt motor. You can purchase a three phase inverter, but the cost will exceed the cost of the new motor sized for the right wiring and voltage.
How many earth wires are required for single phase motor?
There is only one ground wire needed on any motor, single or three phase.
What is the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?
If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.
How do you wire a three phase motor with capacitor start?
I have never come across a three phase capacitor start motor. Any three phase motors I have worked on are induction start.
